Molly crouched behind the hedge, wearing a paper crown that said HAPPY BIRTHDAY, KEVIN. It was the wrong name, the wrong size, and possibly from the wrong century, but she had decided it gave her authority. Across the street, the children’s party blazed with balloons, streamers, and the unmistakable glitter of frosting. Presents were piled beneath a table in the garden, wrapped in bright paper and guarded by a golden retriever with the solemn expression of a retired police commissioner. Bill adjusted his black turtleneck, which was too warm for July and covered in crumbs. “Remind me why we’re stealing from children,” he whispered. “Because adults keep their valuables in banks,” Molly said. “Children keep theirs in gift bags with cartoon dinosaurs on them.” “That doesn’t make it morally better.” “It makes it easier to carry.” Bill peered over the hedge. “How many guards?” “One dog, six parents, fourteen children, and a magician.” “The magician is a problem.” “The magician is eight years old.” “I’ve seen what children can do with invisible thread.” Molly unfolded the blueprint she had drawn on the back of a pizza menu. It showed the garden, the patio, the cake table, and a dramatic arrow labeled ESCAPE. Unfortunately, the arrow led through the inflatable castle. “Our entry point is the side gate,” she said. “We slip in during the piñata. Everyone will be distracted.” “By a papier-mâché donkey?” “Exactly. The oldest trick in the book.” They waited until a father in a party hat began shouting instructions. The children formed a shrieking circle around a bright red piñata. A blindfolded girl swung wildly, striking a shrub, a flowerpot, and Bill’s elbow. He yelped. The children cheered. Molly grabbed his sleeve and dragged him through the gate. They crossed the lawn in a crouch, although Bill’s knees made sounds like two spoons arguing in a drawer. The dog lifted its head. Molly froze. Bill froze. Even the balloons seemed to hold their breath. The retriever rose and padded toward them. “Act natural,” Molly murmured. Bill immediately began walking backward while pretending to be a waiter. “Can I offer you a canapé?” he asked the dog. The dog sniffed his hand, found a sausage roll, and accepted the bribe with professional dignity. They reached the presents. Molly produced a canvas sack. Bill opened the nearest box and found a plush unicorn wearing sunglasses. “Worth anything?” he whispered. “Probably not.” He stuffed it into the sack. “Then why take it?” “For camouflage. No one suspects a thief carrying a unicorn.” “That’s because no one suspects a thief carrying a sack of toys.” A sudden pop echoed across the garden. The piñata had surrendered, scattering sweets like confetti. Children charged toward the patio. Molly snatched three gift bags. Bill grabbed a wrapped rectangle, which immediately began barking. They stared at each other. “That’s not a present,” Bill said. “It has a bow.” “It has lungs.” The dog barked again. Parents turned. Molly shoved the sack at Bill. “Run!” They sprinted for the gate, pursued by children, adults, and the furious birthday dog. Bill tripped over the inflatable castle and landed inside it, bouncing helplessly among the plastic walls. Molly hauled him out by his collar, losing her paper crown in the process. At the hedge, a little boy pointed. “Hey! Those are my presents!” Molly stopped. She looked at the barking package, the plush unicorn, and the crown bearing Kevin’s name. “Bill,” she said, “I think we’ve made a tactical error.” “Several?” “Possibly all of them.” The dog reached them first and sat on Bill’s foot. Molly sighed, surrendered the sack, and handed the boy the unicorn. “Happy birthday,” she said. The boy hugged it. “Thanks, lady.” Bill, pinned beneath the dog, nodded gravely. “Best heist ever.”
