Molly crouched behind a hedge and inspected the suburban house through binoculars. “Four windows on the ground floor,” she whispered. “One side gate, two security cameras, and a balloon arch guarding the front door.” Bill adjusted his black turtleneck, which was three sizes too small and covered in cartoon dinosaurs. “I told you, this is my stealth shirt.” “It says ‘Rawr means I love you.’” “Exactly. No burglar expects emotional vulnerability.” Beyond the hedge, children shrieked around a rented bouncy castle. A banner proclaimed HAPPY BIRTHDAY, MILO! beneath a lopsided drawing of a dragon. Every few seconds, an adult carried another brightly wrapped present into the living room. Molly lowered the binoculars. “The gifts are stacked beside the fireplace. We get in, fill the sack, and leave before the cake.” “How do we get past the party?” “We’re entertainers.” Bill stared at her. “We are thieves.” “Today we’re entertainers who happen to entertain themselves with other people’s property.” She opened a duffel bag. Inside were two fake moustaches, a kazoo, three rubber chickens, and a collapsible cardboard box labeled EMERGENCY CLOWN. Bill picked up the box. “You brought the clown?” “I brought options.” “Last time you brought options, we escaped in a gardening shed.” “That was a successful operation.” “We lived in that shed for six hours.” “Five and a half.” Molly pulled on a purple wig. “The plan is simple. We enter as children’s party magicians, distract everyone with a trick, and I collect the presents.” “What’s my role?” “Assistant.” “I refuse.” “You can be the magician.” “I also refuse. Magicians are expected to know things.” Molly handed him a deck of cards. “Just wave these around confidently.” Bill examined the cards. “They’re all the queen of hearts.” “Consistency builds trust.” They slipped through the side gate and approached the back door. Molly knocked twice, then once. A woman opened it, balancing a tray of cupcakes. “Can I help you?” Molly swept into a bow. “Madam, prepare to witness the astonishing talents of Professor Sparkle and his emotionally available assistant.” Bill waved. “Rawr.” The woman blinked. “You’re the entertainers?” “Surprise,” said Molly. “We’re early,” Bill added. “You’re forty minutes late,” said Molly. The woman glanced toward the screaming children, then sighed. “Fine. Keep them occupied for ten minutes.” “Ten minutes?” Bill muttered as they entered. “That’s not enough time to steal everything.” “It’s enough time to steal selectively.” The living room was a glittering mountain of presents. Molly’s eyes shone. Bill whispered, “What are we taking?” “Anything rectangular, expensive-looking, and not alive.” A child rushed past carrying a plastic sword. “Too late,” Bill said. “That one’s already armed.” Molly climbed onto a footstool and flourished the deck. “Ladies and gentlemen, behold the greatest card trick in history!” The children gathered. Bill leaned toward her. “What’s the trick?” “I make the presents disappear.” “That’s not a trick. That’s the crime.” “Keep smiling.” Bill grabbed a gift and tucked it under his dinosaur shirt. A battery-powered toy began playing a cheerful song. Molly’s smile tightened. “You picked the noisy one.” “I thought music made people happy.” “It makes police happy.” The balloon arch suddenly collapsed, blocking the doorway. The children cheered. Molly seized two more presents. “Move!” Bill waddled after her, stuffed with toys and squeaking with every step. “Why are you squeaking?” “I may have selected something alive.” From beneath his shirt came a muffled quack. Molly stared. “Bill.” “It’s emotionally supportive.” They dove into the emergency clown box as adults entered the room. From inside, Bill whispered, “If we survive, I’m keeping the duck.” Molly whispered back, “If we survive, I’m stealing your shirt.”
