“Tell me again why we’re robbing children,” Bill whispered, crouched behind a hedge shaped like a furious dolphin. “We’re not robbing children,” Molly said. “We’re redistributing luxury goods from tiny, sticky hands to our considerably cleaner hands.” “My hands are clean because you made me wear gloves.” “Exactly. Professionalism.” Across the garden, the birthday party raged beneath a banner reading HAPPY SIXTH BIRTHDAY, OLIVER! The children shrieked around a bouncy castle while a magician pulled scarves from his sleeve with the strained smile of a man being paid in supermarket prosecco. Bill peered over the hedge. “There’s a clown.” “There’s always a clown.” “He’s watching us.” “He’s facing the other way.” “Clowns have mirrors in their souls.” Molly unfolded a hand-drawn map. “The presents are in the conservatory. We enter through the side gate, cross the patio, bypass the sausage rolls, and reach the French doors.” “Bypass the sausage rolls?” “They’re a trap.” “For who?” “For you.” Bill looked wounded. “I have excellent self-control.” A small boy ran past carrying a sausage roll in each hand, one tucked behind his ear. Bill’s eyes followed him with the quiet grief of a poet. Molly tapped the map. “Mrs. Pemberton, Oliver’s grandmother, is stationed beside the presents. She’s eighty-two, wears orthopedic shoes, and suspects everyone of being after the silverware.” “So we distract her.” “We make her think the magician has turned a child into a rabbit.” “Can he do that?” “No.” “Then why would she believe it?” “Because she’s already had three glasses of punch.” Bill nodded slowly. “Punch. The gateway to mistaken zoology.” They slipped through the side gate. Bill immediately stepped on a plastic dinosaur, which gave a shrill electronic roar. Both froze. From the lawn, a child shouted, “My T-Rex!” Bill whispered, “It’s fine. He thinks it’s his.” “It is his.” “Then it’s emotionally fine.” They hurried across the patio. Molly moved like a cat burglar. Bill moved like a cat wearing wet socks. At the conservatory window, Molly glanced inside. A mountain of wrapped presents glittered beneath a table. Beside them sat Mrs. Pemberton, knitting what appeared to be a scarf for a horse. “Showtime,” Molly said. Bill cleared his throat and pushed open the door. “Excuse me, madam. Urgent news. The magician has accidentally transformed Oliver into a rabbit.” Mrs. Pemberton looked up. “Which rabbit?” “Oliver.” “The birthday boy?” “The very same.” She squinted at him. “Is he a nice rabbit?” “Extremely polite. Terrible at algebra.” “Runs in the family.” She set down her knitting. “Where is he?” “Near the bouncy castle,” Bill said. “Possibly chewing a cape.” Mrs. Pemberton rose with impressive speed. “I knew that man had shifty eyebrows.” The moment she left, Molly darted to the presents. “Grab the big ones.” “The big ones are probably toys.” “Correct.” “What are we going to do with fourteen toy robots and a princess castle?” “Sell them.” “To whom?” “Parents. Christmas is only four months away.” Bill picked up a large box. “This one says ‘Oliver, from Mum and Dad.’” “Take it.” “What if it’s something sentimental?” “Then it’ll have excellent resale value.” A voice behind them said, “Are you stealing my presents?” Molly and Bill turned. Oliver stood in the doorway, wearing a paper crown and holding a foam sword. Behind him, the magician’s assistant was trying to remove a rabbit from a punch bowl. Bill smiled weakly. “No.” Oliver narrowed his eyes. “You’ve got my presents.” “We’re testing them,” Molly said. “For what?” “Quality.” “Why?” “Safety standards,” Bill added. “You can’t be too careful with… presents.” Oliver considered this. “Are you from the government?” “Yes,” Molly said. “No,” Bill said at the same time. Oliver raised his foam sword. “Mum! There are burglars!” Molly seized a sack. “Run.” Bill grabbed three boxes and a party bag. “What about the sausage rolls?” “Leave them!” “That’s cruel!” They sprinted through the garden as children cheered, believing it was part of the entertainment. Behind them, the clown began clapping. Bill glanced back in horror. “The clown knows,” he gasped. “The clown always knows,” Molly said.
