Molly crouched behind a hedge, inspecting the mansion through binoculars. Bill balanced beside her in a tuxedo, carrying a sack decorated with dinosaurs. Rain ticked against tablecloths. Inside, children shrieked around a volcano cake while adults clustered near the punch bowl, unaware of the burglary. “Molly, remind me why we aren't stealing from a bank like respectable criminals?” “Because banks rarely contain remote-control dragons.” “What's the plan?” “We enter disguised as entertainers, collect every present, and leave before the birthday song.” “You packed disguises?” “Absolutely. You're the magician; I'm the exhausted clown.” “Why am I the magician?” “Because you already look like someone who has misplaced a rabbit.” Bill frowned, produced a wand from his sleeve, and snapped it immediately. A gust lifted the sack into the hedge. Molly grabbed it, but a squeaker inside honked. The backyard fell silent. A child pressed his nose to the window. Bill waved. “That's encouraging.” “Relax. I brought the getaway vehicle.” “Your bicycle?” “Technically, two bicycles tied together.” “Smile.” “I'm smiling.” “That is your hostage face.” The door opened. A woman shouted. “Who ordered the clown magician?” Molly straightened, seized Bill's hand, and marched toward destiny. “We did.”
