Molly unfurled the blueprints across the hood of the minivan, pinning down the corners with juice boxes. The floor plan of the Peterson residence sprawled before them in meticulous detail, every bounce house and piƱata accounted for. Bill squinted through his binoculars at the backyard, where a clown was currently twisting balloons into what appeared to be either a giraffe or a tragic cautionary tale. "Magicians are the worst witnesses," Bill muttered. The operation required precision. Seven-year-old Timmy Peterson was turning the big eight, and according to their intel, his relatives had wildly overestimated his emotional maturity. Gifts were piled three feet high on the patio table, glittering in wrapping paper like stolen treasure from a particularly glitter-obsessed pharaoh. Molly traced their entry point with a french fry. They'd pose as the entertainment, a husband-and-wife magic duo called The Astonishing Astonishments, and during the disappearing rabbit trick, the presents themselves would disappear. Bill would distract the parents with overly complicated card tricks while Molly loaded the getaway van, disguised cleverly as an ice cream truck. "One problem," Molly said. Neither of them knew any magic tricks. They had six hours and a library card.
