Rain pecked at the windows of the laundromat, where the dryers hummed like bored conspirators and Molly had spread a crayon-colored map across a folding table. It was, technically, a placemat from Pancake Castle, but Bill respected the arrows and circles. “Observe,” Molly said, tapping a drawing of a clown she’d labeled HOSTILE. “The fortress.” “It’s a semi-detached in Croydon.” “Every fortress starts somewhere.” Bill squinted through his fogged spectacles. “And the objective is all the presents?” “All,” Molly said. “Clean sweep. Like Christmas if Christmas had poor supervision and a bouncy castle.” A dryer door thumped open by itself behind them. Bill jumped. “You’re awfully calm about robbing a children’s party,” he said. “I’m not robbing children,” Molly replied. “I’m redistributing surprise.” “To us.” “We’re underfunded adults.” Bill folded his arms. “There’s moral quicksand here.” Molly slid him a biscuit from her coat pocket. “Eat ethics later.” He took a bite despite himself. The biscuit was stale but persuasive. Outside, a delivery scooter hissed past in the wet dark. Inside, the laundromat smelled of soap, steam, and schemes. She pointed to the map again. “Entrance through the side gate. Balloons tied to the latch. If we move carefully, no squeak.” “Balloons squeak by philosophy.” “Then we out-philosophy them.” Molly drew a second circle. “Main hall here. Cake here. Present mountain here.” Bill leaned closer. “Mountain?” “Eight children invited, plus divorced grandparents trying to win affection. We’re talking volume.” He chewed slowly. “And the clown?” “A distractible amateur named Buttons Kevin. Last seen making poodles that looked like orthopedic socks.” Bill considered that. “I distrust any man with two first names.” “Good. Distrust is healthy.” Molly produced a tiny notebook. “Now, timing. At two-fifteen they sing. At two-twenty the cake arrives and every adult becomes a photographer. At two-twenty-one we lift the loot.” “We can’t carry a mountain at two-twenty-one.” “We use the wheelie bins.” Bill stared. “The bins?” “Festive camouflage. No one questions bins at a children’s party. They’re the unsung chariots of wrapping paper.” A child shrieked outside somewhere, though there were no children in sight. Bill rubbed his temples. “I had imagined more elegance.” “You’re thinking of museums,” Molly said. “This is suburbia. Suburbia runs on panic and polypropylene.” He sighed and sat opposite her. “Suppose we get caught by a parent.” “Then we improvise.” “I hate improvise.” “You wore a postman’s uniform into a casino once.” “That was a deeply structured panic.” Molly grinned. She had the grin of a woman who’d never met a plan she couldn’t improve by making it worse first. From her bag she took two paper party hats, one blue, one covered in dinosaurs. “No,” Bill said immediately. “Yes,” said Molly. “Disguise.” “I draw the line at elastic under the chin.” “You don’t have a line. You have anxieties shaped like lines.” Bill took the dinosaur hat and turned it over. “This one says ROARSOME.” “Excellent. You’ll blend.” “With whom, exactly? Unemployed stegosauruses?” “With the atmosphere.” He put it on with the solemnity of a condemned duke. The elastic snapped under his chin and gave him the look of a disappointed toddler. Molly applauded once. “You see?” she said. “Invisible.” “I feel ridiculous.” “Ridiculous is the safest disguise in Britain.” Bill looked down at the map, the arrows, the clown, the mountain of gifts awaiting liberation. A slow smile betrayed him. “All right,” he said. “But if anyone asks, I’m an uncle.” “Perfect,” Molly said, folding the placemat into her pocket. “Nobody trusts an uncle at a buffet. We’ll have the run of the place.”
