Molly crouched behind the hedge, peering through the garden gate at the birthday party beyond. Balloons bobbed above the fence like brightly colored surveillance drones. In the middle of the lawn stood a folding table groaning beneath wrapped presents, each one decorated with enough ribbon to strangle a small magician. Bill adjusted his black knit cap, which had two pink rabbit ears sewn to it. “Are you sure this is a disguise?” Molly whispered. “It’s camouflage,” Bill said. “Children trust rabbits.” “Children trust rabbits who don’t have your face sticking out underneath them.” Bill pulled the cap lower. “Then they’ll assume I’m a very large rabbit.” Inside the garden, a clown attempted to inflate a balloon animal and produced something that looked like a collapsed intestine. Children shrieked with delight. A hired magician waved a wand at a hat while three parents watched with the weary suspicion of people who had paid for entertainment and expected results. Molly unfolded a hand-drawn map. “We enter through the side gate, cross behind the inflatable castle, distract the dog, and reach the presents.” “The dog is a pug,” Bill said. “It can barely reach the ground.” “That makes it unpredictable.” Their target was the largest gift on the table, a box wrapped in silver paper with a tag reading TO JEREMY, FROM EVERYBODY. Around it clustered smaller boxes, gift bags, and one suspiciously lumpy package that Molly had already marked as “potentially valuable.” Bill produced two plastic party hats, a coil of string, and a rubber chicken. “Why the chicken?” Molly asked. “Emergency poultry.” “You brought a rubber chicken to a burglary?” “I brought professionalism.” A gust of wind sent a napkin skittering across the lawn. The pug barked and waddled after it. Molly nodded. “Now.” They slipped through the gate. Molly moved with the silent grace of a burglar who had practiced in narrow hallways. Bill moved with the silent grace of a wardrobe being pushed downstairs. He caught his foot on the string of a balloon and lurched into the inflatable castle. The entire structure shuddered. Several children bounced higher, cheering. “Excellent,” Bill muttered. “We’ve established ourselves as entertainment.” Molly reached the present table and began stuffing packages into a large canvas sack. Bill grabbed the silver box, but the gift tag snagged on a ribbon. He pulled. The ribbon pulled back. The box launched upward, struck the clown’s balloon, and ricocheted into the magician’s hat. The magician stared at it. Bill stared at the magician. Molly stared at Bill. “Take the hat.” Bill snatched the hat and ran. Molly followed, dragging the sack as presents tumbled behind them like festive breadcrumbs. They reached the gate just as the pug arrived, triumphantly carrying the napkin. It dropped the napkin on Bill’s foot and began barking. A dozen children turned. “Rabbit!” one shouted. “Thief!” shouted another. Bill looked at Molly. “Plan B?” Molly vaulted the fence. “Run!” Bill scrambled after her, still wearing the rabbit ears and clutching the magician’s hat. Behind them, the party erupted into applause, convinced the chase was part of the show.
