Molly crouched behind the bouncy castle, peering at the living room window. "Okay, Bill, here's the plan. You're on balloon duty. Pop anything that looks suspicious." Bill adjusted his fake mustache. "Pop balloons? That's loud, Molly." "Then pop them quietly. Think of it as ninja work." She pulled out a tiny clown nose and clipped it onto her collar. "Now, the presents. They're stacked by the piano. Forty-two of them, all wrapped in glittery paper." "Glittery paper is a dead giveaway." "Nobody suspects glitter, Bill. Trust me." She gestured toward the kitchen. "Once the cake is cut, every kid will be sugared up and screaming. That's our window." Bill grinned. "And if someone catches us?" "We say we're the magician. Nobody questions a magician." "Molly, you hired a clown to be the magician." "Details, Bill. Details."
