The van idled behind the bouncy castle warehouse, headlights off, windows fogged with nervous breath. Molly tapped a laminated map of the Henderson twins' birthday party against the steering wheel. Bill sat beside her in a clown wig he had bought for the occasion and was clearly enjoying it far too much. "In through the kitchen," Molly whispered. "Out through the balloon arch." Bill nodded solemnly, adjusting his fake mustache. "And if the magician spots us?" "Pretend to be the magician." Outside, shrieks of delighted children rattled the windows. A gorilla-suited uncle stumbled past carrying a tray of cupcakes, and both thieves ducked below the dashboard. Bill's wig slid over one eye, and he blew it back into place with a huff. Through the fogged glass, they could see the mountain of glitter-wrapped presents stacked beside the birthday cake, each box tied with ribbons large enough to hide a getaway car. Bill glanced down at the bag he had packed, which contained nothing but plastic handcuffs and kazoos. He sighed, wiped his nose on his sleeve, and pulled on a ski mask shaped like a pony. Molly checked her watch, cracked her knuckles, and reached for the door handle. "Let's go steal some birthday loot," she said with a grin.
