Molly crouched behind the hedge, peering through binoculars at the house glowing with balloons, streamers, and the unmistakable menace of a clown-shaped bouncy castle. Bill adjusted his black ski mask, which had tiny yellow ducks printed across it. “Why are there ducks on your face?” Molly whispered. “Camouflage,” Bill said. “Children love ducks. Nobody suspects ducks.” “Nobody suspects competent thieves, either, yet here we are.” Across the garden, a dozen children shrieked around a table stacked with presents. The largest box wore a red bow the size of a satellite dish. A sign beside it read: HAPPY BIRTHDAY, ARCHIBALD! Bill raised his binoculars. “Target confirmed. Presents located. Security consists of one exhausted parent, three grandparents, and a Labrador with the eyes of a detective.” “And the children?” “Unpredictable hostiles.” Molly unfolded a hand-drawn map. It showed the garden, the kitchen, the hallway, and several areas labeled HERE BE TODDLERS. “We enter through the conservatory,” she said. “We blend in, locate the gift pile, and leave through the side gate.” “What do we blend in as?” “Party guests.” Bill looked down at his black trousers, black jumper, and duck mask. “I’m dressed for a party.” “You’re dressed for robbing a silent movie.” “I can make conversation.” “You once introduced yourself to a mirror.” “It was a very convincing mirror.” Molly sighed and produced two paper hats from her coat. One said PRINCESS. The other said DINOSAUR. Bill took the dinosaur. “Finally, a sensible disguise.” They waited until the parent turned toward the cake. Molly sprinted across the lawn. Bill followed, tripped over a skipping rope, and landed inside the bouncy castle with a sound like a punctured trumpet. Every child turned. Molly froze at the conservatory door. A small girl pointed. “That man fell into the castle.” Bill bounced upright. “I meant to do that! I’m the entertainment.” The children cheered. Within seconds, Bill was being pelted with foam balls while Molly slipped inside. She reached the presents just as a grandmother entered carrying a tray of sandwiches. “You’re early,” the grandmother said. “I’m the magician,” Molly replied. “Wonderful. The children adore magic.” Molly glanced at the gift pile. “I specialize in making things disappear.” “Perfect.” She seized the largest box and tucked it under one arm. Unfortunately, it began to meow. Molly stared at it. The grandmother stared at her. From the garden came Bill’s voice. “That’s not a present! That’s Archibald’s cat!” Molly put the box down. “A rehearsal.” “For what?” “Making cats appear.” The grandmother smiled approvingly. “You young entertainers are so inventive.” Molly grabbed three smaller presents and hurried toward the side door. Bill burst through behind her, covered in foam balls and followed by six children. “Emergency!” he gasped. “The audience wants an encore.” “Run!” They fled into the alley, presents clutched to their chests. Behind them, the children applauded wildly. Bill removed his duck mask. “Successful?” Molly examined the boxes. “One is a toaster, one is socks, and one is a book about manners.” Bill nodded. “A valuable lesson.” “What lesson?” “Never rob a party without checking the wrapping.”
