Molly spread the blueprint across the table, jabbing a finger at a crude drawing of a bounce house. "So we go in through the bounce house," she said. "Through the bounce house," Bill repeated, deadpan. "The inflatable one. Full of six-year-olds." "It's a diversion, Bill. Nobody suspects two adults crawling through a bounce house." "Everybody suspects that. That is the single most suspicious thing a person can do." Molly ignored him, tracing a line toward a table marked PRESENTS in red marker. "Once we're in, you distract the clown—" "I am not fighting a clown." "Distracting, not fighting." "Same thing. Clowns fight dirty. Everyone knows this." "Fine, I'll take the clown. You grab the presents and stuff them in the piñata." Bill blinked. "We're stealing presents by hiding them inside a piñata that children are about to beat with a stick?" "It's foolproof." "It is the opposite of foolproof. It is fool-full." Molly rolled up the blueprint with a satisfied snap. "Ten minutes, Bill. In, loot, out. We'll be rich." "We'll be arrested by a birthday clown." "Nobody's ever been arrested by a clown." "There's a first time for everything." She was already halfway out the door. "That's the spirit."
