The van idled three houses down from the birthday party, its headlights off. Through the windshield, the backyard glowed with fairy lights. Somewhere inside, a hundred pounds of sugar was being shoved into toddlers, and a dozen wrapped presents sat in a glittering pile by the gate. Molly tapped the blueprint spread across the dashboard. "Right, Bill. Entry through the bouncy castle. Nobody checks a bouncy castle." "Got it. And the guard?" "Guard's a clown named Doodles. He's been juggling since noon. We wait until he hits the cake table." Bill squinted at the sketch, then at the small X drawn beside the piƱata. "What's this?" "Security camera. Blind spot, supposedly." "Supposedly?" "The kid sitting under it was in the magic show. His eyes were on the rabbit, not the camera." Bill adjusted his fake beard. It itched terribly, and the glue smelled like burnt toffee. He nodded slowly. "And the getaway?" "Ice cream truck. Playing that song, so nobody looks twice." "Molly, I'm nervous. There are forty children in there." Molly grinned, sharp as a paper cut. "Forty witnesses who can't pick a suspect out of a lineup. Trust me. Now put on the mustache."
