Molly spread the blueprint across the table, jabbing her finger at a crayon drawing of a castle. "This is our target. Timmy Peterson's seventh birthday party. Bouncy castle, clown, the works." Bill squinted. "You want us to rob a seven-year-old?" "Not him, genius. The presents. Twenty kids, twenty presents, probably full of cash-value electronics these days." "Molly, there's gonna be parents everywhere. And a clown." "The clown's the distraction. Clowns are terrifying. Nobody watches presents when there's a clown doing balloon animals." Bill crossed his arms. "I don't like clowns." "Nobody likes clowns, Bill, that's the point. We go in dressed as entertainers—magician and assistant. Slip out back with the gift table while Frosty the Clown does his creepy little dance." "What if a kid notices?" "Kids are morons. Give one a lollipop, he forgets his own name." "This feels wrong." "It's a birthday party, Bill. Presents are basically unclaimed property at that point." Bill sighed, pulling on a sequined vest. "If we get caught, I'm blaming the clown." "Deal." Molly grinned, tucking a fake mustache into her pocket. "Now let's go steal some Legos."
