Rain tapped the skylight of the abandoned conservatory in a rhythm that sounded suspiciously like a slow clap. Beneath a hanging fern that had died of disappointment years ago, Molly spread a hand-drawn map across a wicker table missing one leg. Bill steadied the wobble with a stack of old gardening catalogues and regarded the map with the solemnity of a man planning to invade Belgium rather than a suburban semi-detached with a bouncy castle in the garden. “Right,” said Molly, tapping a jam stain near the driveway. “Target is the Henderson place. Two o’clock tomorrow. Peak chaos. Peak sugar. Peak parental inattentiveness.” Bill adjusted his spectacles, which had no lenses and existed mainly to make him look like a respectable accountant of crime. “And we’re certain there’ll be enough presents to justify the risk?” “It’s a sixth birthday,” Molly said. “Six is the golden age of loot. Relatives still care, parents are still trying, and nobody’s old enough to ask for practical items. We’re talking plastic abundance.” Bill nodded gravely. “Good. I won’t crawl through a hedge for educational puzzles.” Molly pointed to the back gate. “Entry here. The clown arrives at one-thirty. Every eye will be on the fellow making balloon giraffes and low-level trauma. We blend in.” “In what capacity?” Bill asked. “I can’t do face paint again. Last time I made a tiger look like a tax dispute.” “You’re not face paint,” said Molly. “You’re entertainment logistics.” “That sounds made up.” “So is half of crime.” A gust rattled the glass. Somewhere in the conservatory, a loose pane gave a nervous shiver. Bill leaned closer. “Talk me through extraction.” “We bag the presents from the gift table, exit through the side path, load the van, and vanish before cake-cutting.” Bill frowned. “Too clean. Children are sticky. Nothing involving them is ever clean.” “Fine,” said Molly. “Moderately sticky extraction.” “And disguises?” Molly opened a duffel bag. Inside lay two lurid tabards, one reading PARTY CREW, the other in brighter letters reading SUPER PARTY CREW. Bill stared as if she’d revealed a dead raccoon. “I refuse to be Super Party Crew,” he said. “You’re taller. It gives authority.” “It gives visibility.” “It gives confidence to the host.” “I don’t want to inspire confidence in anyone holding a tray of sausage rolls.” Molly shrugged. “Then be normal Party Crew. I’ll be super.” Bill blinked. “That somehow feels worse.” Outside, thunder muttered over the allotments. Molly rolled up the map and tucked it into her coat with the satisfaction of an admiral. “Any known obstacles?” Bill asked. “Grandparents,” said Molly instantly. “Unpredictable. They sit quietly, then suddenly know everybody’s business.” Bill shuddered. “Veterans. All of them.” “And one terrier,” Molly added. “Name of Pickles. Low to the ground, high in suspicion.” “I hate a dog with a comic name,” said Bill. “It gives them confidence.” Molly pulled a notepad from her pocket. On it was written OPERATION HAPPY RETURNS in red marker, underlined twice. “We’ll need tools. Gift sacks, cable ties, decoy clipboard, emergency bubbles.” “Emergency bubbles?” “If cornered, you blow bubbles,” Molly said. “Adults become idiots around bubbles. It buys us seconds.” Bill considered this. “You know, that’s appallingly plausible.” “Thank you.” He looked again at the map. “And morally, where do we stand on stealing from children?” Molly leaned back, chair creaking. “We are not stealing from children. We are intercepting goods before distribution. It’s logistics.” “That is the most criminal sentence I’ve heard all week.” “It’s a growth sector.” Bill rubbed his chin. “What if there’s a magician?” “Then we adapt.” “I don’t trust magicians,” he said. “Too much professional overlap.” Molly grinned. “Bill, tomorrow at two, while small people scream at a man in oversized shoes, we shall liberate a mountain of unopened treasure and disappear into history.” Bill slowly smiled back. “All right. But if I end up carrying a giant plush octopus, I’m charging extra.” “You’ll be lucky,” said Molly, rising and snapping the bag shut, “if that isn’t exactly what makes the job worth doing.”
