Molly crouched behind the hedge, peering at the bouncy castle where shrieking kids swarmed like sugar-crazed locusts. Bill squeezed in beside her, clutching a comically small backpack shaped like a dinosaur. "This is the worst idea you've ever had," she whispered, "and you've had some stinkers." Bill grinned, adjusting his rainbow party hat. "Come on, Mol. Those presents are practically begging to be liberated. Think of it as redistribution of wealth. To us." "They're six-year-olds, Bill. Their idea of security is a balloon tied to the gift table." "Exactly. Childproof, not thief-proof." He pulled out two clown masks and offered her one. "We go in during musical chairs. Chaos is our friend." Molly stared at the mask. "If we get caught, I'm telling them you're my idiot cousin from out of town." "Fair enough." Bill checked his watch. "PiƱata breaks in seven minutes. That's our window. You grab the big shiny ones, I'll create a diversion with the bubble machine." She sighed, slipping on the mask. "I can't believe I'm about to ruin a birthday for a stack of gift cards and whatever the hell is in those My Little Pony boxes." "Think of the loot," Bill said, eyes gleaming. "And the story. Nobody's ever heisted a children's party before. We'll be legends." "Legends in therapy," Molly muttered, but she followed him toward the laughter anyway.
