Molly and Bill crouched behind a hedge shaped like an enormous rabbit, studying the back garden of Number Twelve, where balloons bobbed above the fence like colorful warning buoys. Beyond them came the shriek of sugar-drunk children and the brittle cheer of a hired clown. Bill lowered the binoculars. “I’m just saying, on the scale of crimes, robbing a bank feels classier than pinching gifts from a six-year-old’s birthday.” Molly adjusted the black silk scarf around her neck as if preparing for an opera rather than a burglary. “Class doesn’t pay rent. Also, banks have lasers. Children have cake and poor perimeter security.” A paper hat sailed over the fence and landed near Bill’s shoe. He stared at it with suspicion. “That’s exactly the sort of trap I’d expect.” “From who? The Fairy Godmother Task Force?” “Mock all you like. I once underestimated a christening and left with a fork in my shoulder.” Molly peered through a gap in the hedge. In the center of the lawn stood a long table groaning under wrapped parcels in every shape and size, guarded only by a sleepy spaniel in a birthday bow. “Target is visible. No adults within immediate present radius. We go in, lift the loot, and vanish before they finish singing.” Bill leaned closer. “There’s a clown.” “Yes.” “I hate clowns.” “You hate escalators, pigeons, and yoghurt with fruit in the bottom.” “That’s caution, Molly. Clowns are personal.” Inside the garden, a magician in a sequined waistcoat produced a stream of scarves while the children screamed as though witnessing dark sorcery. The smell of sausages drifted over the fence and made Bill’s moral crisis look increasingly hungry. Molly unfolded a hand-drawn map on her knee. It had arrows, timings, and a sketch of the spaniel labeled POSSIBLE NARC. “You enter as the balloon man. You’ve got the apron, the pump, the dead-eyed smile. I circle through the side gate disguised as Aunt Linda.” “We don’t know an Aunt Linda.” “Every family has one. Floral jacket, vaguely disappointed expression, asks where the loo is. No one questions it.” Bill rubbed his chin. “And when the presents are moved?” “We use the wheelie bin extraction.” His face brightened despite himself. “That is elegant.” “I know.” A child’s voice rose over the fence: “Mum! Oscar ate the blue icing and now he’s barking!” Bill winced. “Place is descending into chaos already.” “Chaos is a ladder,” Molly said. “Chaos is usually why I lose a shoe.” She folded the map and slid it into her sleeve. The side gate clicked open as a harassed father hurried out carrying a tray of juice boxes, then dashed back in without latching it. Molly and Bill stared at the opening in reverent silence. Bill whispered, “That, right there, is the universe inviting us in.” “No,” Molly murmured. “That is amateur hosting.” They slipped through the gate into a world of bunting and spilled squash. No one glanced at them. Molly instantly transformed, shoulders drooping into middle-aged authority. Bill grabbed a cluster of balloons from a crate and arranged his face into festive despair. A little girl tugged his sleeve. “Can you make me a unicorn?” Bill looked stricken. “I can make you a regrettable sausage dog.” Molly glided to the present table and casually began loading gifts into the wheelie bin beside it, covering each box with a layer of paper plates. The spaniel watched, yawned, and went back to sleep. “Bill,” she called pleasantly, “do keep up.” He twisted a balloon with the concentration of a safecracker. “I’m creating a diversion.” The balloon exploded like a gunshot. Every child in the garden screamed and ran toward him in delight. Molly grinned, hauled the now bulging bin toward the gate, and said, “Perfect. You’ve finally found your audience.” Bill, surrounded by chanting children demanding swords, flowers, and dinosaurs, gave her a haunted look. “If I survive this, I’m stealing from pensioners next time.”
