Text to rewrite: <text words="606"> 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>

The gallery remained closed to the public starting Tuesday. Detective Nadia Voss ducked under the police tape and entered inside. The floors, polished just days prior by the cleaning crew, allowed her footsteps to echo off the marble surface. Someone had forced open the front door with a crowbar, leaving deep, jagged gouges in the frame. Nadia crouched down to examine the splintered wood. The intruder had pried away the lock and discarded it carelessly. "Someone with real experience did this," Nadia commented to Sergeant Tomás Delgado, who stood near the open security panel. "Not some random vandal with a brick." "Definitely not," Tomás agreed. He pointed at the wires within the unit. "Check out those cuts — clean and precise, no tearing. And they even removed the backup battery to avoid any surprises." Nadia stood back up and headed into the large hall. The missing painting, the Whitmore, had once hung on the north wall. All that remained now were metal brackets and the foundational frame, which was leaned against the baseboard. The diamond-studded canvas was sliced cleanly from its timber enclosure. "The Whitmore," she whispered. "Who would've guessed Crane ended up with it after all?" "Value wise, that old painting was worth more than this whole building," Tomás noted. "Maybe he finally let it get to his ego. Walking around bragging at every reception like that..." A guest list, passed on from the gallery owner, Mr. Crane, listed twenty-three individuals who attended Monday's private viewing. Nadia had marked out the list itself from her pocket, scanning the names. Crane had then circled two entries in red ink for further attention. "Who departed early that evening, and can anyone account for them?" Nadia inquired. "Two guests - solid alibis, though," Tomás replied, rifling through his notes. "But no one can confirm who drove the catering van out at midnight." Nadia furrowed her brow in concern. She made her way to the rear corridor, where the night guard had discovered the theft. The emergency door swung freely, propped open by a solid brick. Muddy boot prints lined the entrance. "The intruder came through the back, that much is clear," she noted. "But how did they pinpoint the camera to target?" "It got spray-painted at 11:15," Tomás chimed in, joining her. "The others just kept recording, but that lone camera, lost forever. Not a whole lot there to go on..." All other surveillance feeds remained untouched, yet only the one covering the rear entrance had been thoughtfully disabled. Nadia inspected the boot prints more closely, crouching down. They were sizable, nearly a size twelve, with even imprint spacing. "An official assessment happened just last month from the insurance company," she shared upon overhearing the painting's three million dollar value. "This case won't resolve quickly - of that much, I'm sure. Nevertheless, such clumsy scattering of evidence, as if they neared the finish line..." </text><>
