Molly crouched by the hedge outside Maple Street Community Hall, listening to tinny kiddie music float through the vents. Bill held a roll of bubble wrap like it was sacred evidence. The plan was simple: infiltrate the clown-free birthday party, disable the gift table’s alarm—whatever that was—and walk out before anyone noticed the missing loot. They’d practiced on a mall Santa display, but this time the doors were timed to a moral soundtrack and the security guard was a teenager with a Nintendo. “Molly, gloves first,” Bill whispered. Molly pulled on glittery rubber gloves she’d stolen from a craft store. “Relax, we'll take the presents and leave the cake,” Molly said. She nudged the bubble wrap toward Bill. “Deal—tonight,” Bill grinned. Inside, balloons bobbed like jellyfish. Someone screamed with joy, which meant guards were distracted by squealing. Molly slipped behind the candy buffet, using her backpack as a rolling decoy while Bill worked the gift pile with surgical calm. Crinkling paper echoed; no one cared. The guest of honor was busy hugging a stuffed dinosaur that looked suspiciously like evidence. Molly wiggled her eyebrows at Bill as the bag filled, and the dinosaur’s birthday hat fell off—conveniently unnoticed by everyone.
