The gallery had been closed to the public since Tuesday. Detective Nadia Voss ducked under the yellow tape and stepped inside. The floors had been polished by the cleaning crew just days ago, and her footsteps echoed off the marble.</explain> Let’s start with the first sentence: “The gallery had been closed to the public since Tuesday.” This is passive voice (“had been closed”). The agent is the gallery management/owner. We can change it to active voice by inferring the agent as “the gallery staff” or simply “management” for clarity. A more fluid approach might be: “The gallery staff had closed the gallery to the public since Tuesday,” but that’s repetitive. Better: “The gallery had remained closed to the public since Tuesday.” Actually, that’s still passive. Let's try: “Gallery management had kept the gallery closed to the public since Tuesday.” But the original is passive, and we need to make it active. How about: “The gallery had shut its doors to the public since Tuesday.” That is active (“had shut”). Yes. But wait, the instructions say: “Convert all passive voice constructions to active voice. Where no agent is named, infer the correct agent from surrounding context.” So we need to identify the agent. Original: “The gallery had been closed to the public since Tuesday.” Agent: likely gallery management or staff. So: “Gallery management had closed the gallery to the public since Tuesday.” But that changes the structure slightly. Another way: “The gallery had remained closed to the public since Tuesday” is not passive (remained is a linking verb). Actually, “had been closed” is passive, “had remained closed” is not passive. So that might be acceptable, but is it active voice? “Remained” is intransitive, so it’s not passive but also not active voice in the sense of an action performed by an agent. However, the instruction is to convert passive voice to active voice. So we need an active verb with an agent. Or we could say: “The gallery’s management had closed it to the public since Tuesday.” But that might be too specific if the agent isn’t clearly established elsewhere. Looking ahead, there is mention of “gallery staff” later. So we can infer “staff” or “management.” Let’s go with “Gallery staff had closed the gallery to the public since Tuesday.” But the original sentence’s focus is on the state of being closed, not who closed it. Changing it to active might alter the emphasis. Perhaps we can use “The gallery had shut its doors to the public since Tuesday.” That uses “the gallery” as the agent (metaphorically), which is active voice. Yes. Let’s check the second sentence: “Detective Nadia Voss ducked under the yellow tape and stepped inside.” That’s active voice. No change. Third: “The floors had been polished by the cleaning crew just days ago, and her footsteps echoed off the marble.” This is passive (“had been polished by the cleaning crew”). To convert to active: “The cleaning crew had polished the floors just days ago, and her footsteps echoed off the marble.” That works. Next: “The front door had been forced open by the intruder.” Passive: “had been forced open by the intruder.” Active: “The intruder had forced open the front door.” Yes. Next: “Deep gouges scarred the frame where a crowbar had been used by whoever broke in.” Passive: “had been used by whoever broke in.” Active: “Deep gouges scarred the frame where whoever broke in had used a crowbar.” That sounds a bit awkward. Original: “Deep gouges scarred the frame where a crowbar had been used by whoever broke in.” We could say: “Deep gouges scarred the frame where the intruder had used a crowbar.” But “whoever broke in” is the agent, so we can keep that: “Deep gouges scarred the frame where whoever broke in had used a crowbar.” That’s active. Next: “Nadia crouched and examined the splintered wood.” Active. Next: “The lock had been pried loose and tossed aside.” Passive without agent. Agent: the intruder. So: “The intruder had pried the lock loose and tossed it aside.” But we need to infer agent from context: earlier “whoever broke in” or “the intruder.” We can use “The intruder” to avoid repetition. However, we have to be careful about switching agents. Maybe “Someone had pried the lock loose and tossed it aside.” That is active. Now dialogue: “Looks like they knew what they were doing,” she said... Leave unchanged. Next narration: “He pointed at the open panel.” Active. Next: “The alarm system had been disabled by someone with technical knowledge — the wires had been cut cleanly, not ripped out.” Two passives: “had been disabled” and “had been cut.” Agent: “someone with technical knowledge” for the first, and presumably the same for the second. So: “Someone with technical knowledge had disabled the alarm system — they had cut the wires cleanly, not ripped them out.” Or “Someone with technical knowledge had disabled the alarm system and had cut the wires cleanly, not ripped them out.” But there’s also “A backup battery had also been removed.” Passive: “had also been removed.” Agent: same someone. So: “They had also removed a backup battery.” But we need to connect sentences. Original: “The alarm system had been disabled by someone with technical knowledge — the wires had been cut cleanly, not ripped out. A backup battery had also been removed.” We can combine: “Someone with technical knowledge had disabled the alarm system, cutting the wires cleanly instead of ripping them out, and had also removed a backup battery.” That reads well. Next: “The security system had been installed by a private firm only two years earlier.” Passive: “had been installed by a private firm.” Active: “A private firm had installed the security system only two years earlier.” Yes. Next: “Nadia straightened up and walked toward the main hall.” Active. Next: “The stolen painting had been displayed on the north wall by the gallery staff for Monday's private viewing.” Passive: “had been displayed by the gallery staff.” Active: “The gallery staff had displayed the stolen painting on the north wall for Monday's private viewing.” But note “stolen painting” — it’s already stolen, but in the past it was displayed. That’s fine. Next: “Only the mounting brackets remained.” Active. Next: “The canvas had been sliced from its frame with a blade, and the frame itself had been left propped against the baseboard.” Two passives: “had been sliced” (agent: thief) and “had been left” (agent: thief). So: “The thief had sliced the canvas from its frame with a blade and had left the frame itself propped against the baseboard.” But we need to infer agent: the thief. We can use “Someone” or “The thief.” Since we haven’t identified the thief specifically, “Someone” might be better. But later they refer to “the thief.” Let’s keep consistent. Dialogue: “The Whitmore,” she murmured. ... Leave. Next narration: “It was worth more than this whole building,” Tomás said. Active. Next: “Crane bragged about it at every opening night. He must be devastated.” Active. Next: “A guest list had been compiled by the gallery owner, Mr. Crane, and handed to the police that morning.” Passive: “had been compiled by Mr. Crane” and “handed” (implied “had been handed”). Active: “The gallery owner, Mr. Crane, had compiled a guest list and handed it to the police that morning.” Yes. Next: “Nadia pulled the folded sheet from her jacket pocket and scanned the names.” Active. Next: “Twenty-three guests had been invited to Monday's viewing.” Passive: “had been invited.” Agent: Mr. Crane or his staff. So: “Mr. Crane had invited twenty-three guests to Monday's viewing.” Or “The gallery had invited twenty-three guests.” But from context, Crane compiled the list, so he likely invited them. We'll go with “Mr. Crane had invited twenty-three guests to Monday's viewing.” Next: “Every one of them had been vetted by Crane's staff before the event.” Passive: “had been vetted by Crane's staff.” Active: “Crane's staff had vetted every one of them before the event.” Yes. Next: “Two names had been circled in red by Crane himself.” Passive: “had been circled by Crane himself.” Active: “Crane himself had circled two names in red.” Yes. Dialogue: “Was anyone unaccounted for after ten o'clock?” Nadia asked. Active. Response: “Two guests left early,” Tomás said, flipping through his notes. Active. Next: “I already checked — both alibis hold up.” Active. Next: “But the caterer's van wasn't logged out until midnight.” Passive: “wasn’t logged out.” Agent: someone (the caterer or security). We need to infer who logs out vehicles: likely security personnel. So: “But security hadn’t logged out the caterer's van until midnight.” Or “But no one had logged out the caterer's van until midnight.” Actually, “wasn’t logged out” is passive. We can say: “But the caterer's van had left without being logged out until midnight.” That’s still passive. Better: “But the caterer's van had departed without anyone logging it out until midnight.” That’s active but changes structure. Alternatively: “But no one had logged the caterer's van out until midnight.” That works. Next: “Nobody can tell me who was driving it.” Active. Next: “Nadia frowned.” Active. Next: “She turned toward the back corridor.” Active. Next: “The theft had been reported by the night guard at dawn — hours after the thief had come and gone.” Passive: “had been reported by the night guard.” Active: “The night guard had reported the theft at dawn — hours after the thief had come and gone.” Yes. Next: “The emergency exit had been propped open with a brick, and muddy boot prints had been tracked across the threshold.” Two passives: “had been propped open” and “had been tracked.” Agents: thief for both. So: “The thief had propped open the emergency exit with a brick and had tracked muddy boot prints across the threshold.” But “tracked” is usually something the person does, so “had tracked” is active already? Actually “had been tracked” is passive. So “had tracked” is active. So: “The thief had propped open the emergency exit with a brick and tracked muddy boot prints across the threshold.” Good. Next: “The brick had been wiped clean of fingerprints.” Passive: “had been wiped.” Agent: thief. So: “The thief had wiped the brick clean of fingerprints.” Yes. Dialogue: “Someone came in through the back,” she said. Active. Next: “That much is obvious.” Active. Next: “The question is how they knew exactly which camera to hit.” Active. Next: “Chen pulled the security footage this morning,” Tomás said, following her. Active. Next: “The rear camera was spray-painted over at eleven fifteen.” Passive: “was spray-painted.” Agent: thief. So: “The thief had spray-painted over the rear camera at eleven fifteen.” But note: “was spray-painted over” is passive. Alternatively: “Someone had spray-painted over the rear camera at eleven fifteen.” Yes. Next: “Everything else kept rolling, but that one angle — gone.” Active. Next: “Nothing useful after that.” Active. Next: “The remaining cameras had been left untouched — only the one covering the back entrance had been targeted.” Two passives: “had been left untouched” and “had been targeted.” Agents: thief. So: “The thief had left the remaining cameras untouched — only the one covering the back entrance had attracted their attention.” But “had been targeted” passive. So: “The thief had targeted only the camera covering the back entrance, leaving the others untouched.” That rephrases but keeps meaning. Next: “Nadia crouched beside the boot prints.” Active. Next: “They were deep and evenly spaced — size eleven, maybe twelve.” Active. Next: “The prints had been photographed by the forensics team, but she wanted to see them for herself.” Passive: “had been photographed by the forensics team.” Active: “The forensics team had photographed the prints, but she wanted to see them for herself.” Yes. Next: “A formal appraisal had been conducted by the insurance company just last month — the painting had been valued at three million.” Two passives: “had been conducted by the insurance company” and “had been valued.” Active: “The insurance company had conducted a formal appraisal just last month — they had valued the painting at three million.” Or “The insurance company had formally appraised the painting just last month, valuing it at three million.” That’s smoother. Next: “Nadia stood and brushed off her knees.” Active. Next: “The case would not be solved quickly — she was certain of that.” Passive: “would not be solved.” Agent: unclear (the police, her). So: “She knew she would not solve the case quickly.” Or “She was certain she wouldn't solve the case quickly.” But the original emphasizes the case being solved, not who solves it. We can infer “she” as agent from context (she is the detective). So: “She would not solve the case quickly — she was certain of that.” But that changes meaning slightly: “she” personally solving vs. the case being solved in general. Maybe: “The case would defy a quick solution — she was certain of that.” That is active but not a direct conversion. Better: “She was certain the case would not see a quick resolution.” That is active. Alternatively: “She was certain she wouldn’t crack the case quickly.” That’s active and retains the meaning. Next: “But the evidence had been scattered carelessly, almost deliberately, as though the thief wanted to be found.” Passive: “had been scattered.” Agent: thief. So: “But the thief had scattered the evidence carelessly, almost deliberately, as though they wanted to be found.” Yes. Now we need to assemble the entire rewritten text, making sure to keep the same writing style, word choice, and sentence structure intact as much as possible while converting passives to actives. Also note: We must leave dialogue inside quotation marks unchanged. So we only change narration. Let's compose the rewritten text step by step, referencing the original paragraphs. Original: <text>The gallery had been closed to the public since Tuesday. Detective Nadia Voss ducked under the yellow tape and stepped inside. The floors had been polished by the cleaning crew just days ago, and her footsteps echoed off the marble. The front door had been forced open by the intruder. Deep gouges scarred the frame where a crowbar had been used by whoever broke in. Nadia crouched and examined the splintered wood. The lock had been pried loose and tossed aside. "Looks like they knew what they were doing," she said to Sergeant Tomás Delgado, who stood near the security panel. "This wasn't some teenager with a brick." "Not even close," Tomás replied. He pointed at the open panel. "Look at the wiring — clean cuts, no tearing. They even knew about the backup." The alarm system had been disabled by someone with technical knowledge — the wires had been cut cleanly, not ripped out. A backup battery had also been removed. The security system had been installed by a private firm only two years earlier. Nadia straightened up and walked toward the main hall. The stolen painting had been displayed on the north wall by the gallery staff for Monday's private viewing. Only the mounting brackets remained. The canvas had been sliced from its frame with a blade, and the frame itself had been left propped against the baseboard. "The Whitmore," she murmured. "Three years ago it almost went to auction. I can't believe it ended up in a place like this." "It was worth more than this whole building," Tomás said. "Crane bragged about it at every opening night. He must be devastated." A guest list had been compiled by the gallery owner, Mr. Crane, and handed to the police that morning. Nadia pulled the folded sheet from her jacket pocket and scanned the names. Twenty-three guests had been invited to Monday's viewing. Every one of them had been vetted by Crane's staff before the event. Two names had been circled in red by Crane himself. "Was anyone unaccounted for after ten o'clock?" Nadia asked. "Two guests left early," Tomás said, flipping through his notes. "I already checked — both alibis hold up. But the caterer's van wasn't logged out until midnight. Nobody can tell me who was driving it." Nadia frowned. She turned toward the back corridor. The theft had been reported by the night guard at dawn — hours after the thief had come and gone. The emergency exit had been propped open with a brick, and muddy boot prints had been tracked across the threshold. The brick had been wiped clean of fingerprints. "Someone came in through the back," she said. "That much is obvious. The question is how they knew exactly which camera to hit." "Chen pulled the security footage this morning," Tomás said, following her. "The rear camera was spray-painted over at eleven fifteen. Everything else kept rolling, but that one angle — gone. Nothing useful after that." The remaining cameras had been left untouched — only the one covering the back entrance had been targeted. Nadia crouched beside the boot prints. They were deep and evenly spaced — size eleven, maybe twelve. The prints had been photographed by the forensics team, but she wanted to see them for herself. A formal appraisal had been conducted by the insurance company just last month — the painting had been valued at three million. Nadia stood and brushed off her knees. The case would not be solved quickly — she was certain of that. But the evidence had been scattered carelessly, almost deliberately, as though the thief wanted to be found.</text> Now, applying changes: First paragraph: - “The gallery had been closed to the public since Tuesday.” -> “The gallery had shut its doors to the public since Tuesday.” (Active) - “Detective Nadia Voss ducked under the yellow tape and stepped inside.” (unchanged) - “The floors had been polished by the cleaning crew just days ago, and her footsteps echoed off the marble.” -> “The cleaning crew had polished the floors just days ago, and her footsteps echoed off the marble.” Second paragraph: - “The front door had been forced open by the intruder.” -> “The intruder had forced open the front door.” - “Deep gouges scarred the frame where a crowbar had been used by whoever broke in.” -> “Deep gouges scarred the frame where whoever broke in had used a crowbar.” - “Nadia crouched and examined the splintered wood.” (unchanged) - “The lock had been pried loose and tossed aside.” -> “Someone had pried the lock loose and tossed it aside.” Third paragraph (dialogue unchanged): - “The alarm system had been disabled by someone with technical knowledge — the wires had been cut cleanly, not ripped out.” -> “Someone with technical knowledge had disabled the alarm system, cutting the wires cleanly instead of ripping them out.” - “A backup battery had also been removed.” -> “They had also removed a backup battery.” (But note: “They” refers to “someone with technical knowledge.” However, we need to maintain continuity. Alternatively: “That person had also removed a backup battery.” But “they” is acceptable as singular they.) - “The security system had been installed by a private firm only two years earlier.” -> “A private firm had installed the security system only two years earlier.” Fourth paragraph: - “Nadia straightened up and walked toward the main hall.” (unchanged) - “The stolen painting had been displayed on the north wall by the gallery staff for Monday's private viewing.” -> “The gallery staff had displayed the stolen painting on the north wall for Monday's private viewing.” - “Only the mounting brackets remained.” (unchanged) - “The canvas had been sliced from its frame with a blade, and the frame itself had been left propped against the baseboard.” -> “Someone had sliced the canvas from its frame with a blade and had left the frame itself propped against the baseboard.” Dialogue paragraphs unchanged. Fifth paragraph: - “A guest list had been compiled by the gallery owner, Mr. Crane, and handed to the police that morning.” -> “The gallery owner, Mr. Crane, had compiled a guest list and handed it to the police that morning.” - “Nadia pulled the folded sheet from her jacket pocket and scanned the names.” (unchanged) - “Twenty-three guests had been invited to Monday's viewing.” -> “Mr. Crane had invited twenty-three guests to Monday's viewing.” (But careful: earlier we said “Crane” compiled the list, but maybe the invitations were sent by the gallery. However, since Crane is the owner, it’s plausible. Alternatively: “The gallery had invited twenty-three guests.” But we need to infer agent from context: Crane is the owner and compiled the list, so he likely invited them. We'll go with “Mr. Crane.”) - “Every one of them had been vetted by Crane's staff before the event.” -> “Crane's staff had vetted every one of them before the event.” - “Two names had been circled in red by Crane himself.” -> “Crane himself had circled two names in red.” Dialogue unchanged. Sixth paragraph: - “But the caterer's van wasn't logged out until midnight.” -> “But no one had logged out the caterer's van until midnight.” (Active) - Other dialogue unchanged. Seventh paragraph: - “The theft had been reported by the night guard at dawn — hours after the thief had come and gone.” -> “The night guard had reported the theft at dawn — hours after the thief had come and gone.” - “The emergency exit had been propped open with a brick, and muddy boot prints had been tracked across the threshold.” -> “The thief had propped open the emergency exit with a brick and tracked muddy boot prints across the threshold.” - “The brick had been wiped clean of fingerprints.” -> “The thief had wiped the brick clean of fingerprints.” Dialogue unchanged. Eighth paragraph: - “The rear camera was spray-painted over at eleven fifteen.” -> “Someone had spray-painted over the rear camera at eleven fifteen.” (Active) - Other dialogue unchanged. Ninth paragraph: - “The remaining cameras had been left untouched — only the one covering the back entrance had been targeted.” -> “The thief had left the remaining cameras untouched — only the one covering the back entrance had drawn their focus.” But “had been targeted” passive. Better: “The thief had targeted only the camera covering the back entrance, leaving the others untouched.” - “Nadia crouched beside the boot prints.” (unchanged) - “They were deep and evenly spaced — size eleven, maybe twelve.” (unchanged) - “The prints had been photographed by the forensics team, but she wanted to see them for herself.” -> “The forensics team had photographed the prints, but she wanted to see them for herself.” Tenth paragraph: - “A formal appraisal had been conducted by the insurance company just last month — the painting had been valued at three million.” -> “The insurance company had conducted a formal appraisal just last month — they had valued the painting at three million.” - “Nadia stood and brushed off her knees.” (unchanged) - “The case would not be solved quickly — she was certain of that.” -> “She was certain she wouldn’t crack the case quickly.” (Active) - “But the evidence had been scattered carelessly, almost deliberately, as though the thief wanted to be found.” -> “But the thief had scattered the evidence carelessly, almost deliberately, as though they wanted to be found.” Now, we need to ensure consistency in referring to the thief. Sometimes we used “the thief,” sometimes “someone,” sometimes “they.” It’s fine as long as it’s clear. We also need to maintain the original sentence structure and style as much as possible. Some changes might alter the flow slightly, but we aim to keep it similar. Let’s write the full rewritten text: [Rewrite] --- The gallery had shut its doors to the public since Tuesday. Detective Nadia Voss ducked under the yellow tape and stepped inside. The cleaning crew had polished the floors just days ago, and her footsteps echoed off the marble. The intruder had forced open the front door. Deep gouges scarred the frame where whoever broke in had used a crowbar. Nadia crouched and examined the splintered wood.

But no one had logged out the caterer's van until midnight. Nobody can tell me who was driving it." Nadia frowned. She turned toward the back corridor. The night guard had reported the theft at dawn — hours after the thief had come and gone. The thief had propped open the emergency exit with a brick and tracked muddy boot prints across the threshold. The thief had wiped the brick clean of fingerprints. "Someone came in through the back," she said. "That much is obvious. The question is how they knew exactly which camera to hit." "Chen pulled the security footage this morning," Tomás said, following her. "Someone had spray-painted over the rear camera at eleven fifteen. Everything else kept rolling, but that one angle — gone. Nothing useful after that." The thief had targeted only the camera covering the back entrance, leaving the others untouched. Nadia crouched beside the boot prints. They were deep and evenly spaced — size eleven, maybe twelve. The forensics team had photographed the prints, but she wanted to see them for herself. The insurance company had conducted a formal appraisal just last month — they had valued the painting at three million. Nadia stood and brushed off her knees. She was certain she wouldn’t crack the case quickly. But the thief had scattered the evidence carelessly, almost deliberately, as though they wanted to be found. --- Check if any passive constructions remain. - “The gallery had shut its doors” – active. - “The cleaning crew had polished” – active. - “The intruder had forced open” – active. - “whoever broke in had used” – active. - “Someone had pried” – active. - Dialogue unchanged. - “Someone with technical knowledge had disabled” – active. - “They had also removed” – active. - “A private firm had installed” – active. - “The gallery staff had displayed” – active. - “Someone had sliced” – active. - Dialogue unchanged. - “Mr. Crane had compiled” – active. - “Mr. Crane had invited” – active. - “Crane's staff had vetted” – active. - “Crane himself had circled” – active. - Dialogue unchanged. - “no one had logged out” – active. - “The night guard had reported” – active. - “The thief had propped open” – active. - “The thief had wiped” – active. - Dialogue unchanged. - “Someone had spray-painted” – active. - Dialogue unchanged. - “The thief had targeted” – active. - “The forensics team had photographed” – active. - “The insurance company had conducted” – active. - “they had valued” – active. - “She was certain she wouldn’t crack” – active. - “the thief had scattered” – active. All passives converted. Also, note that we changed “was spray-painted” to “had spray-painted” to maintain past perfect tense consistent with other verbs? Original: “The rear camera was spray-painted over at eleven fifteen.” That is simple past passive. We converted to past perfect “had spray-painted” because other actions are in past perfect (had disabled, had propped, etc.). But we should keep tense consistency. However, the original uses a mix of past simple and past perfect. We should match the original tense where possible. Let's check original tense usage: - First sentence: “The gallery had been closed...” past perfect passive. We changed to past perfect active “had shut.” - “The floors had been polished” -> past perfect active “had polished.” Good. - “The front door had been forced” -> past perfect active “had forced.” - “a crowbar had been used” -> past perfect active “had used.” - “The lock had been pried” -> past perfect active “had pried.” - “The alarm system had been disabled” -> past perfect active “had disabled.” - “the wires had been cut” -> past perfect active “had cut” (but we incorporated into “cutting the wires”). - “A backup battery had also been removed.” -> past perfect active “had removed.” - “The security system had been installed” -> past perfect active “had installed.” - “The stolen painting had been displayed” -> past perfect active “had displayed.” - “The canvas had been sliced” -> past perfect active “had sliced.” - “the frame itself had been left” -> past perfect active “had left.” - “A guest list had been compiled” -> past perfect active “had compiled.” - “Twenty-three guests had been invited” -> past perfect active “had invited.” - “Every one of them had been vetted” -> past perfect active “had vetted.” - “Two names had been circled” -> past perfect active “had circled.” - “the caterer's van wasn't logged out” -> simple past passive. We changed to past perfect active “had logged out.” But note: “wasn't logged out” is negative simple past. We made it “no one had logged out” which is past perfect affirmative. Might change tense slightly. Could do “But the caterer's van had left without anyone logging it out until midnight.” But that’s wordy. Alternatively: “But no one logged out the caterer's van until midnight.” That’s simple past active. Which is better? The original uses past perfect for prior actions, but this is part of Tomás's report about events that night. We'll keep past perfect for consistency. - “The theft had been reported” -> past perfect active “had reported.” - “The emergency exit had been propped open” -> past perfect active “had propped.” - “muddy boot prints had been tracked” -> past perfect active “had tracked.” - “The brick had been wiped” -> past perfect active “had wiped.” - “The rear camera was spray-painted” -> simple past passive. We changed to past perfect “had spray-painted.” Might be okay because it’s also a prior action. But we could use simple past active: “Someone spray-painted over the rear camera at eleven fifteen.” That might match the dialogue’s tense. However, the surrounding narration uses past perfect for actions before the investigation. The spray-painting happened before the investigation, so past perfect is fine. We'll keep “had spray-painted.” - “The remaining cameras had been left untouched” -> past perfect active “had left.” - “only the one covering the back entrance had been targeted” -> past perfect active “had targeted.” - “The prints had been photographed” -> past perfect active “had photographed.” - “A formal appraisal had been conducted” -> past perfect active “had conducted.” - “the painting had been valued” -> past perfect active “had valued.” - “The case would not be solved quickly” -> passive future. We changed to “She was certain she wouldn’t crack the case quickly.” which is future in past (wouldn’t crack) – matches tense. - “the evidence had been scattered” -> past perfect active “had scattered.” So overall, we maintained past perfect where original used past perfect passive, and changed to past perfect active. That’s consistent. One more check: In dialogue, Tomás says: “The rear camera was spray-painted over at eleven fifteen.” We left dialogue unchanged, so that remains passive. But earlier we changed the narration version? Actually, the line “The rear camera was spray-painted over at eleven fifteen.” is part of Tomás's dialogue, so we must leave it unchanged. Wait, in the original text, that sentence is within Tomás's dialogue? Let's see original: "Chen pulled the security footage this morning," Tomás said, following her. "The rear camera was spray-painted over at eleven fifteen. Everything else kept rolling, but that one angle — gone. Nothing useful after that." Yes, the sentence is within his dialogue, inside quotation marks. So we should NOT change it. I mistakenly included it in the narration changes. In my rewritten text above, I changed it to “Someone had spray-painted over the rear camera at eleven fifteen.” but that is not dialogue? Actually, in the original, it's part of Tomás's speech. So we must leave it as is: “The rear camera was spray-painted over at eleven fifteen.” Because the instruction says: "Leave dialogue inside quotation marks unchanged." So we cannot change that sentence. In my rewrite, I wrote: “Someone had spray-painted over the rear camera at eleven fifteen.” That is incorrect because it’s dialogue. We need to revert that line to the original passive voice. Let's correct: In the rewrite, the paragraph after dialogue should be: "Chen pulled the security footage this morning," Tomás said, following her. "The rear camera was spray-painted over at eleven fifteen. Everything else kept rolling, but that one angle — gone. Nothing useful after that." Then narration continues: “The remaining cameras had been left untouched...” which we changed to active. So we need to adjust. Thus, the only passive voice that remains should be inside dialogue. All narration passives are converted. Now, double-check the dialogue sections: They are all inside quotes, so they stay as is. That includes “The rear camera was spray-painted over at eleven fifteen.” and any other dialogue lines. So final rewritten text should have dialogue unchanged. Let's produce final output with that correction. Final version: The gallery had shut its doors to the public since Tuesday. Detective Nadia Voss ducked under the yellow tape and stepped inside. The cleaning crew had polished the floors just days ago, and her footsteps echoed off the marble. The intruder had forced open the front door. Deep gouges scarred the frame where whoever broke in had used a crowbar. Nadia crouched and examined the splintered wood. Someone had pried the lock loose and tossed it aside. "Looks like they knew what they were doing," she said to Sergeant Tomás Delgado, who stood near the security panel. "This wasn't some teenager with a brick." "Not even close," Tomás replied. He pointed at the open panel. "Look at the wiring — clean cuts, no tearing. They even knew about the backup." Someone with technical knowledge had disabled the alarm system, cutting the wires cleanly instead of ripping them out. They had also removed a backup battery. A private firm had installed the security system only two years earlier. Nadia straightened up and walked toward the main hall. The gallery staff had displayed the stolen painting on the north wall for Monday's private viewing. Only the mounting brackets remained.
