The van idled behind the community center, headlights off, engine sputtering like a nervous hamster. Molly unfolded a blueprint across the dashboard and tapped a sketch of a bouncy castle. "Kitchen window," she said. Bill squinted at the paper, then at a crayon drawing taped beside it. "Is that a clown?" he asked, pointing. "Ignore it," Molly said. She pulled a black ski mask over her curls and tossed him a matching one, pink with a unicorn horn. "Absolutely not." Bill held it up like a dead fish. "I'm not robbing a birthday party dressed as a unicorn." "Nobody looks at the masked guy." Through the brick wall came a ragged chorus of "Happy Birthday," wobbling badly off key. Bill sighed, pulled on the unicorn hat, and checked his watch. The presents were stacked in the living room, wrapped in glittery paper, each one tagged with a child's name in careful, lopsided letters. "Ten minutes," he whispered. Somewhere inside, a seven-year-old shrieked with joy, and both thieves froze, guilt flickering across their faces like a candle in a draft. Molly swallowed hard and reached for the door handle. "Right. Go."
