Bill pressed his face to the cracked frosting of a decorative window, squinting like a detective in a cartoon. “Okay, Molly, don’t panic. We’re basically ninjas.” Molly adjusted her ridiculous striped beanie, the kind that looked like it came from a bakery that sold hats to pigeons. “I’m not panicking. I’m pre-celebrating your inevitable brilliance.” Bill straightened and aimed a tiny flashlight through the fogged glass. Through it, they could see balloons bobbing like cheerful ghosts, tables sagging under cupcakes, and a clown-shaped piñata wearing a permanent look of betrayal. “Look at that,” Bill whispered. “So… many… presents.” Molly’s eyes shone with the greedy tenderness of a raccoon being offered a single grape. “Gifts are just treasure with wrapping paper. And children have the emotional stamina of wet paper towels, so they’ll never notice.” Bill turned toward her, lowering his voice as if the party could hear. “They will notice when the floor starts to feel lighter.” “The floor will feel lighter because you’ll be carrying out a whole sled of joy,” Molly said. “They’ll just assume the magic spirits took the presents to recharge.” Bill sighed. “You’ve been watching too much bedtime television.” Molly leaned closer to the door, where a plastic “No Running” sign was taped slightly crooked, like it had been defeated by an optimistic child. “Bedtime television? Bill, I have a degree in Crime Studies.” “You do not.” “I do. It’s from a community college,” she said, then glanced at her backpack. “I’m also credentialed in snacks.” Bill opened his own bag with a faint click, producing a roll of tape, a handful of glow sticks, and a collapsible ladder that looked like it had been assembled from pool noodle segments. “I thought we were stealing presents, not auditioning for a camp counselor.” “Everything’s an audition,” Molly said. “Now hush. We have a schedule.” Bill nodded gravely. “Right. Phase one: establish entry. Phase two: locate loot. Phase three: escape before someone asks if we’re the new magic show.” Molly pointed to the side of the house, where a gate latch sat in plain view. “Phase one is already happening. That latch is basically begging for a gentle persuasion.” Bill reached into his pocket and pulled out a small tool that looked like a paperclip’s anxious cousin. “Gentle persuasion, huh? I’m more of a forceful persuasion guy.” Molly smirked. “You’ll have your moment. Just don’t set off the doorbell.” Bill froze. “There’s a doorbell?” Molly stared at him, then at the porch. “Bill. There’s always a doorbell.” “That is a deeply unhelpful philosophy.” “Shh,” Molly whispered. She pressed her ear to the gate. Inside, the music from a kids’ playlist thumped cheerfully, punctuated by squeals and the sound of someone dropping something soft. Bill tried to look confident. “Okay. Quietly now. Like—like we belong here.” Molly lifted her hands. “We do belong here. We’re just early.” Bill bent down and worked the latch. Click. The gate swung open with a sound that, in any other scenario, would have been normal. Unfortunately, this scenario involved a house whose walls seemed to amplify every tiny mistake like a microphone strapped to guilt. From inside, a voice called, “Mom? Where are the presents?” Bill’s eyes went wide. “Oh no.” Molly, without missing a beat, stepped forward as if she owned the lawn. “We’re not here to steal gifts, sweetheart. We’re here to protect them from—” Bill hissed, “We can’t protect what we haven’t—” A woman appeared in the doorway, still smiling, phone in hand, eyes scanning for party chaos. “Do you two need something?” Molly’s mouth opened and closed twice, as if it was buffering. “Um. Hello. Yes. We are… the present guardians.” Bill saluted with two fingers, which immediately looked suspicious because he had grease on his knuckles. “We saw a suspicious—uh—safety issue.” The woman blinked. “Are you with the clown company?” Molly glanced at Bill’s beanie, then at her own striped hat. “We’re more like… surprise safety clowns.” Bill nodded too enthusiastically. “Exactly. Safety. Also, we brought… glow sticks.” The woman’s smile widened, probably because she had never met someone who admitted to crime so confidently. “That’s wonderful! The kids are going to love those. Just—come in, please.” Molly and Bill exchanged a look: their expressions screaming the same word in different accents. Permission. Bill whispered, “We got in.” Molly whispered back, “Don’t celebrate yet.” They stepped through the doorway like two misfiled invoices, and Molly immediately spotted the main pile of wrapped boxes under a banner that read HAPPY BIRTHDAY, as if the letters themselves were dared to be stolen.
