The rain drummed on the van roof while Molly squinted through binoculars at the backyard across the street, where a bouncy castle sagged under a mountain of wrapped presents. Bill sat beside her, crunching a sandwich he had clearly lifted from a child's lunchbox at the school gate. "Remind me why we're robbing a birthday party?" he asked. Molly lowered the binoculars and sighed. "Because nobody guards presents, Bill. Trust me, I've checked." Bill frowned at the cheerful banner stretched across the fence, which read Happy Sixth Birthday, Tyler! in glitter letters that somehow looked menacing under the streetlight. He wiped crumbs from his coat and tried to look like a man with a plan. A plan, he reasoned, was just a list of things that would probably go wrong, and they already had three of those. Molly grinned, pulled a black ski mask over her curls, and slid open the van door. Somewhere inside the house, children shrieked over a piƱata, blissfully unaware that their gift pile was about to become the most efficiently looted in town history. Bill climbed out after her, nearly tripping over a rogue balloon that bounced cheerfully against his shoe.
