Molly crouched behind a hedge, studying the house through binoculars that magnified everything except important parts: doors, windows, and cake apparently according to Bill today. “Target confirmed,” Bill whispered. “Several gift boxes, one inflatable dinosaur, and a suspiciously enormous piñata. We enter quietly, collect everything, and vanish before anyone notices.” Bill wore a black turtleneck, black gloves, and socks, though his bright yellow rain boots made him resemble a burglar hired by a cheerful duck. “Molly, stealth is a state of mind.” Bill adjusted his boots. “Also, these have excellent traction. If I slip, I’ll slide directly beneath the buffet.” Molly lowered binoculars. Inside, children ricocheted between tables while an exhausted clown attempted balloon animals with the grim concentration of a surgeon operating during turbulence. “Plan B,” Molly said. “We disguise ourselves as entertainers, distract the adults, and load presents into the getaway van while pretending this is perfectly normal.” Bill opened their equipment case, revealing two capes, a kazoo, three rubber chickens, and a document labeled Emergency Excuses, Volume Seven, with several pages missing. “Why Volume Seven?” Molly asked. “What happened to the first six?” “Mostly arrests,” Bill said. “And one incident involving a mayor, a unicycle, and custard.” They approached the side gate, where a hand-painted sign announced, NO RUNNING, NO SCREAMING, AND ABSOLUTELY NO PROFESSIONAL THIEVES allowed under any circumstances today, apparently. “Good news,” Bill whispered. “They anticipated amateurs, not professionals.” “Molly, we are not professionals.” “Exactly. We’re amateurs with superior planning and extremely limited options tonight somehow.” Molly produced a hairpin, a spoon, and a tiny framed photograph of Bill wearing a medal marked World’s Okayest Pickpocket from his proudest afternoon ever. “Why the spoon?” Bill asked. “For the lock.” “That’s not how locks work.” “It is if the lock is soup.” “And I remain optimistic tonight about everything.” At the kitchen window, Bill lifted a cape over his head. The fabric snagged on a rosebush, yanking him backward into a decorative wheelbarrow outside. “Remain calm,” Molly said. “I’m calm.” “You’re wearing the wheelbarrow.” “It’s part of the disguise.” “Then disguise yourself as someone who can walk without accessories.” They slipped inside during children’s laughter. Molly scooped wrapped gifts into a sack while Bill approached the clown who handed him balloon poodle without explanation. “Behold,” Bill announced, presenting the balloon. “A hound.” “That is a sausage with ears.” “Art is subjective.” “Then subject it to the sack and move.” The clown squinted, suspicious. Bill panicked and released rubber chickens. They clucked across the floor causing three toddlers, two parents, and a poodle to chase them. “Molly,” Bill hissed, “the distraction is working.” “Excellent. Load faster.” “Where’s the van?” “Behind the house.” “Where’s the house you just entered through that window?” Molly pointed toward the exit, but a little girl blocked it, clutching a glittery present. She examined the thieves’ sack, then their matching yellow boots. “Are you magicians?” the girl asked. “Absolutely,” Molly said. “We make presents disappear.” “Can you make my brother disappear?” Bill nodded. “For a modest fee.”
