Rain polished the alley behind Mrs. Wimple’s Community Hall until the bins shone like guilty emeralds. Above them, paper lanterns bobbed in the upstairs windows, and every few seconds the glass flashed with the colors of a magician’s wand or a balloon sword duel gone terribly diplomatic. Somewhere inside, twenty children were shrieking in the key of sugar. Molly crouched beneath a sagging poster for tap-dancing lessons and peered at the kitchen door through opera glasses she’d stolen from a disappointed aunt in 2018. Bill stood beside her in a caterer’s jacket that fit like a pillowcase on a lamp. “This,” said Molly, lowering the glasses, “is either our finest hour or the exact moment we should have become florists.” Bill adjusted his paper hat. “Florists get up at dawn. Criminals have standards.” The wind carried the smell of icing, sausage rolls, and fresh wrapping paper. Across the alley, a cardboard pirate was taped to a window, smiling with all the confidence of a man who had never met actual thieves. Molly unfolded the plan from her pocket. It had once been a bus timetable and still contained, inconveniently, the 42 to Dagenham. She tapped it with a gloved finger. “Kitchen entrance here. Hallway here. Present table near the bouncy castle. We go in with the cake trolley, nod like professionals, fill the empty cake boxes with gifts, and leave before anyone notices that the magician has accidentally set fire to his own scarf again.” Bill frowned. “And if there isn’t a cake trolley?” “There is always a cake trolley. Civilisation depends on it.” From upstairs came a mighty chorus of children chanting for someone named Trevor to open the big one. Bill visibly blanched. “That’s our problem right there,” he whispered. “A party reaches present-opening and suddenly time matters.” Molly looked up at the lit windows, calculating. She had the expression of a woman who could estimate the resale value of a toy robot by the sound of its batteries. “Then we move fast. No dithering, no souvenirs, and absolutely no getting emotionally attached to anything plush.” Bill held up both hands. “One time. One time I rescued a stuffed giraffe from a skip.” “You named it Admiral Longneck and tried to teach it cards.” “He was a quick study.” She folded the plan and slipped it away as the kitchen door banged open. A harassed man in an apron stumbled out, carrying a tower of pizza boxes and muttering about napkins, children, and the end of patience as a concept. He propped the door with his foot, shouted for someone called Denise, then disappeared back inside, forgetting both the door and the boxes. Molly and Bill stared. Bill smiled first. “The universe has sent us room service.” “Don’t get spiritual on me,” Molly said, though she was already moving. They crossed the alley with the solemn speed of people pretending not to run. Inside the kitchen, steam clouded the windows and three adults were arguing over candles shaped like dinosaurs. Nobody looked at them. Molly slid the pizza boxes onto a rack, seized two empty cake cartons, and marched for the hall. Bill followed, carrying himself with the hunched confidence of a man who hoped invisibility might be contagious. The party exploded around them. Balloons drifted at ankle height. A clown on stilts drank tea in a corner with the grave expression of an exhausted bishop. At the far end of the room stood the present table, glittering beneath a banner that read HAPPY 7TH BIRTHDAY, OLIVE! and sagged on the Y like a warning. “Remember,” Molly murmured, smiling at a passing grandmother, “we are invisible professionals.” Bill smiled back at the grandmother so hard she recoiled. “I’m nailing it.” They reached the table. Molly flipped open a carton and began transferring parcels with crisp, efficient hands: dinosaurs, dolls, suspiciously expensive plastic bricks. Bill grabbed a gift shaped like a telescope and another that rattled ominously. Then a small voice piped up behind them. “That one’s mine,” said a little boy in a paper crown, pointing at Bill’s carton. “I know because I wrapped it badly.” Bill turned with the expression of a man caught burgling by a tax inspector. Molly, without missing a beat, bent to the boy’s level. “Excellent,” she said. “Quality control. You can never be too careful with wrapping.”
