Molly spread the blueprints across the folding card table, pinning the corners down with half-empty juice boxes she'd stolen for reconnaissance purposes. The layout of the Peterson residence glowed under her desk lamp like a treasure map drawn by a kindergartner, which, technically, it had been. Bill hunched beside her, chewing the end of a bendy straw with the intensity of a man defusing a bomb. The party was scheduled for Saturday at two o'clock, which gave them exactly seventy-two hours to perfect what Molly had dubbed Operation Cake Walk. Ten children. Approximately forty-seven gift bags. One bouncy castle that would serve as both distraction and, potentially, getaway vehicle if things went sideways. Bill tapped the backyard perimeter, where a clown named Mister Giggles was contracted to perform magic tricks between two and three. "Clown's ours by two-fifteen," Bill muttered. Molly nodded, circling the piñata location in red marker. The piñata itself was irrelevant, but the swinging stick posed a genuine threat to their escape route along the hedgerow. She sketched in little stick figures representing parents, assigning each one a threat level based on caffeine intake and apparent fitness, and underlined the grandmother twice.
