Molly crouched behind a hedge shaped like a walrus and inspected the rented mansion. Paper planets hung from the porch. A banner announced, WELCOME, CAPTAIN PIP! in letters large enough to be read from orbit. Through the windows came the shrieks of children, the clatter of paper plates, and a song about dinosaurs that had apparently lost all musical structure. Bill adjusted his bow tie, which was decorated with tiny flashing cupcakes. “Tell me again why I’m dressed like a birthday magician.” “Because the real magician is trapped in traffic, and because nobody suspects a man carrying a rabbit.” “Your rabbit is a handbag.” “It has ears.” “It has a zipper.” “Details. The presents are stacked beside the fireplace. We stroll in, perform a little distraction, and stroll out with the loot.” Bill peered at the window. “By loot, you mean gifts from children.” “Temporarily misplaced gifts from children.” “Molly, that is the same sentence with a hat on.” She straightened, smoothing her silver jacket. “We need a clean operation. No alarms, no screaming, no accidentally joining the conga line.” “You joined the conga line last time.” “It was moving toward the exit.” “It moved toward the chocolate fountain.” “And I escaped through the chocolate fountain.” “You were wearing white trousers.” “Which made the escape memorable.” A miniature astronaut burst through the front door, collided with a shrub, and vanished into the foliage. A woman shouted, “Captain Pip, get back here!” Somewhere inside, a kazoo began playing a tune that sounded like a police siren having a nervous breakdown. Bill swallowed. “Perhaps we should steal something less guarded. Silverware. A vase. The family dog.” “The dog is wearing a party hat and knows karate.” “How do you know?” “He kicked me when I tried to borrow his collar.” Molly lifted the rabbit handbag. “We enter as entertainment. I make the adults laugh. You collect the presents.” “Collect them where?” “In the rabbit.” Bill stared at the handbag. “That rabbit is smaller than a sandwich.” “It’s a professional rabbit.” “It’s vinyl.” “Vinyl is very discreet.” They slipped through the side gate and approached the service door, where a handwritten sign read NO UNINVITED MAGICIANS, CLOWNS, PIRATES, OR ACCOUNTANTS. Molly knocked anyway. A boy opened the door. He wore a cardboard crown and held a plastic sword. “Are you the entertainment?” he asked. “Absolutely,” said Molly. “Can you make my sister disappear?” “Only temporarily.” “Can you make homework disappear?” “Now you’re asking for advanced magic.” Bill leaned forward. “Where are the presents?” The boy pointed. “Under the table. But you have to beat Dad at musical chairs.” Molly smiled. “Of course.” Bill whispered, “We’re doomed.” Inside, the adults cheered as Molly took the last chair, Bill tripped over a balloon, and the cardboard crown became lodged on his head. By the third round, he was carrying six wrapped presents, a piñata, and the family’s enormous birthday cake. “Plan change,” Molly announced. “What’s the new plan?” Bill panted. “We steal the cake.” “Finally, a sensible crime.” Then Captain Pip emerged from the hedge, pointed at them, and shouted, “They’re the burglars!” Molly handed Bill the cake. “Run.” “Where?” “Toward the chocolate fountain!” This time, they both wore white trousers.
