“Tell me again why we’re robbing a children’s party?” “Because, Bill, the invitations say ‘bring your best disguise,’ and nobody suspects a penguin.” “You’re dressed as a magician.” “I changed my mind.” “You’re wearing one of my trousers.” “Magicians need pockets.” “We’re stealing presents from children.” “We’re liberating them from unreliable wrapping paper.” “Molly.” “Fine. We’re stealing presents from children, but only the ones labeled ‘From Grandma.’ Grandmas overpack. Those boxes are practically shouting, ‘I contain something expensive and vaguely scented.’” Bill peered over the garden hedge. “The party is in there. Thirty children, two clowns, a bouncy castle, and one terrifying woman holding a tray of cupcakes.” “That’s Mrs. Pickle.” “You know her?” “She once caught me stealing a ceramic goose.” “Why were you stealing a ceramic goose?” “It was a limited edition.” “Molly, this is not a plan. This is a series of bad decisions wearing a hat.” “Speaking of hats, yours is magnificent.” “I’m dressed as a birthday cake.” “A very convincing birthday cake.” “It has armholes.” “That’s the genius of it.” A child sprinted past the window wearing a cardboard crown. “Look!” Molly whispered. “The presents are stacked beside the sofa.” “Guarded by the dog.” “The dog is twelve years old.” “The dog is looking directly at me.” “He’s blind.” “He can still judge.” “Everyone in this neighborhood can judge. That’s why we work at night.” “Then why are we here at three in the afternoon?” “Because children’s parties have cake.” “Ah. At last, a respectable motive.” Molly pulled a silver spoon from her sleeve. “Phase one: infiltration. We walk in confidently.” “Wearing a magician costume and a cake costume?” “Confidence is ninety percent of disguise.” “What’s the other ten percent?” “Not having frosting on your face.” Bill wiped his cheek. “That’s not frosting.” “Then you have a worse problem.” They approached the gate. A woman blocked their path. “Who are you?” Molly raised her hands dramatically. “The entertainment!” Bill bowed, causing his cardboard icing to wobble. “And the cake.” “The magician and the cake,” the woman repeated. “Exactly,” Molly said. “We perform together.” “What’s your act?” Molly snapped her fingers. “I make presents disappear.” The woman narrowed her eyes. “You’re the children’s magician?” “Absolutely.” Bill murmured, “We are?” “Absolutely,” Molly repeated. Inside, the children cheered as Molly produced a rabbit from her sleeve. Bill stared. “Where did you get that?” “Never mind. Distract them.” “Ladies and gentlemen!” Bill shouted. “Prepare to witness the world’s first flying cake!” He stumbled toward the bouncy castle. The children followed, laughing. Molly slipped beside the presents and lifted a box. A small voice said, “That one’s mine.” Molly froze. “Of course it is.” “What are you doing?” “Checking the label.” “It says ‘To Toby.’” “I’m Toby’s aunt.” “I don’t have an aunt who’s a magician.” “You do now.” Bill returned, breathless. “Abort mission. The dog has found my leg.” The old dog clung to his trouser cuff, growling magnificently. Molly sighed and placed the box back. “Fine. We’ll steal cake instead.” “Is that still a crime?” “Only if we take the whole one.” They escaped through the kitchen window carrying three cupcakes, a paper crown, and the rabbit, who seemed disappointed by the lack of loot.
