Molly crouched behind the hedge opposite number seventeen, peering through binoculars with one cracked lens. Across the street, a garden bloomed with balloons, streamers, and a bouncy castle shaped like a dragon with digestive issues. Children shrieked happily. Parents milled around guarding paper plates of cupcakes. A table beneath a striped canopy sagged under a mountain of wrapped presents. Bill lay beside her in a camouflage jacket that matched absolutely nothing in suburban Britain. “Target acquired,” Molly said. “That’s a lot of presents,” Bill whispered. “Fifty-three by my count.” “You counted the tiny ones?” “Tiny ones are where jewelry hides.” “At a seven-year-old’s party?” “Rich people are unpredictable.” Bill adjusted his fake moustache, which was upside down. “Remind me why we’re stealing birthday presents from children?” “Because,” Molly said, lowering the binoculars, “we are not stealing them. We are liberating suspicious packages from a potentially dangerous environment.” “Are any of them dangerous?” “That one has glitter paper.” “Fair.” A girl in a princess dress ran past the gift table wielding a foam sword. A father wearing a dinosaur tail chased her, roaring with the exhausted despair of a man who had signed up for themed parenting. Molly unfolded a crayon map of the garden. “We enter through the side gate during musical statues.” “How do we know when that happens?” Bill pointed. “There’s a woman plugging in speakers.” “Good. Once the music starts, everyone freezes.” “Children freeze. Adults panic about photos.” “Exactly. We go in disguised as entertainers.” Bill looked down at the duffel bag. “I still think two clowns would be better.” “No clowns. Clowns attract attention.” “Says the woman carrying a tuba.” “It’s a distraction tuba.” “It has no valves.” “It’s very distracting.” Bill sighed. “What are our entertainer names again?” “You are Professor Gigglebucket.” “I object.” “And I am Madame Twinkleboots.” “I withdraw my objection.” Molly opened the duffel. Inside were sequined waistcoats, a rubber chicken, two party hats, a coil of rope, and a clipboard labeled OFFICIAL PRESENT INSPECTION UNIT. Bill lifted the clipboard. “This feels legally shaky.” “It has laminated edges.” “Ah. Government, then.” The music boomed to life: a pop song sung by someone with too much enthusiasm and not enough vowels. Children began dancing wildly. Parents raised phones. The woman at the speaker shouted, “Musical statues!” Molly snapped her waistcoat on. “Move.” They hurried across the road, not running exactly, but performing the brisk waddle of people who hoped confidence was an invisibility cloak. At the side gate, Molly produced a lockpick. Bill frowned. “It’s not locked.” “I know.” “Then why the lockpick?” “For morale.” She opened the gate. They slipped into the garden as the music stopped. Children froze in poses of heroic chaos. One boy stood with a sausage roll in each hand and terror in his eyes. Molly marched to the gift table. “Official inspection!” A nearby mother blinked. “Sorry, what?” Bill beamed. “Professor Gigglebucket, ma’am. Parcel safety.” Molly tapped the clipboard. “New regulations. Ribbons, bows, choking hazards, suspicious rattles.” The mother hesitated. “No one told me about that.” “Classic council,” Bill said. “They never tell anyone,” Molly added. The music restarted. Children resumed flailing. Molly began placing presents into the duffel with professional solemnity. Bill whispered, “This is actually working.” “Of course it’s working.” “That boy is staring.” “Wave.” Bill waved with the rubber chicken. The boy waved back, then pointed at the duffel. “Mum! The clowns are taking Katie’s presents!” Molly stiffened. “We are not clowns.” The music stopped. Silence slapped the garden. Every child turned. Every parent turned. Even the dragon bouncy castle seemed judgmental. Bill cleared his throat. “Quality control?” Katie, the birthday girl, stepped forward. She wore a crown, glitter shoes, and the expression of a small monarch facing treason. “Those are mine.” Molly looked at Bill. Bill looked at Molly. “Plan B?” he whispered. “Plan B.” Molly reached into the bag and pulled out the tuba. She put it to her lips and produced a noise like a goose falling down stairs. Children screamed with laughter. Bill began juggling cupcakes badly. One hit him in the forehead, another landed in a grandmother’s handbag, and the third vanished into the dinosaur father’s open mouth. “Entertainment diversion successful!” Bill cried. Molly bowed, then returned the presents one by one, lining them neatly on the table. “Inspection complete. All packages dangerously delightful.” Katie narrowed her eyes. “Are you real entertainers?” Bill removed the upside-down moustache. “We’re in training.” Molly added, “Very early training.” Katie considered this. “Can you make balloon animals?” Molly glanced at the balloons tied to the fence. “I can make balloon worms.” “For twenty minutes,” Bill said, “she once made a snake.” Katie smiled slowly. “Fine. But no stealing.” “Absolutely not,” Molly said. “Never,” Bill said. A parent handed them party hats with suspicion. Soon Molly was twisting balloons into tragic sausages while Bill led a game called Pass the Chicken, which had no rules and three winners every round. The presents remained untouched beneath the canopy. As dusk settled, Katie handed them each a slice of cake in a napkin. “Best party ever,” she declared. Bill watched her skip away. “We are terrible thieves.” Molly bit into the cake. “Yes.” “So we’re retiring?” “Don’t be ridiculous.” “What’s next?” She nodded toward the buffet table. “We steal the mini quiches.” Bill smiled. “Now that’s a victimless crime.”
