Molly spread the blueprints across the sticky diner table, pinning down the corners with ketchup bottles and a half-eaten plate of hash browns. The layout of the Peterson residence looked deceptively simple: kitchen, living room, backyard, and the sacred epicenter of their operation—the gift table, currently estimated to hold seventeen wrapped packages of unknown but potentially lucrative contents. Bill squinted at the diagram, tracing a greasy finger along the proposed entry route through the side gate. His clown costume hung on the back of the booth, the red nose dangling from one oversized pocket like an incriminating cherry. He'd spent three days practicing balloon animals and still couldn't manage anything more sophisticated than a lopsided snake, which he'd been told was just a regular balloon. "The magician bails at three," Molly said. That was their window. Thirty minutes of chaos during the pin-the-tail transition, when parents would be distracted by lukewarm coffee and the birthday boy would be hopped up on frosting. Bill would create a diversion involving a malfunctioning juggling routine while Molly, disguised as Aunt Linda, swept the presents into an oversized diaper bag. Bill frowned. "I hate kids."
