Molly had stolen diamonds, payrolls, and once, by administrative error, a municipal snowplow, but nothing unsettled her like the invitation on Bill's kitchen table. It showed a grinning dinosaur wearing a party hat and promised games, balloons, and presents. Around it, Bill had arranged crayons as if they were blueprints. "We enter as clowns, grab gifts, leave laughing." Molly peered through binoculars at the house across the street. Children ricocheted in the yard, powered by frosting and war cries. A pony stood near the hydrangeas, judging everyone. The front porch sagged beneath parcels wrapped in pirates, princesses, rockets, and suspicious glitter. "And if they hate clowns?" Bill tapped the crayon map. His mustache twitched with professional optimism. He had labeled the bouncy castle "escape tunnel" and the cake table "distraction volcano." Molly, meanwhile, had circled Mrs. Peabody, the grandmother, three times. The old woman carried a handbag large enough for a safe and moved with the calm menace of a museum laser grid. "Then we become magicians, obviously." A shriek rose as someone lost a balloon to the sky. Bill swallowed. "With cake?" Molly adjusted her fake red nose, sighed, and checked the getaway wagon for wobbling wheels and honor.
