The safe house was a laundromat that had given up on laundering and committed itself entirely to mildew. At midnight, under a flickering sign that read SP N CYCLE, Molly spread a hand-drawn map across an upside-down detergent bucket and tapped the crayon outline of a suburban semi-detached house with the solemnity of a field marshal. Bill leaned over it, wearing a black turtleneck and the expression of a man trying very hard to look like he understood crayons at a strategic level. Outside, rain drummed on the boarded window. Inside, a lonely dryer turned one squeaking sneaker in circles like a tiny captive moon. “Right,” said Molly. “Tomorrow, fourteen hundred hours, Operation Happy Grab begins.” Bill squinted at the map. “Why is the target house pink?” “Because it was the only crayon left. Focus.” “And why is the dog drawn larger than the garage?” “Because the dog is a tactical concern and the garage is architecture. Try to keep up.” Bill folded his arms. “I’m just saying, if we’re going to rob a children’s party, I’d prefer the documents to inspire confidence.” “We are not robbing children,” Molly said. “We are relieving inattentive adults of custody over commercially excessive gift parcels.” “That sounds more evil somehow.” She ignored him and pointed with a biro. “Entrance here. Side gate. Balloon arch. Inflatable dinosaur. We blend with the hired entertainment.” Bill blinked. “There’s hired entertainment?” “A magician, allegedly. Which means one underpaid man with a rabbit-shaped grudge and a top hat held together by court orders. We outclass him immediately.” “With what? Sleight of hand?” “With posture,” said Molly. “And confidence. People will forgive almost anything if you carry a coil of rope and look annoyed.” Bill considered this. “That explains my uncle’s second marriage.” Molly slid two laminated cards across the bucket. They read FUN SQUAD EVENT LOGISTICS in heroic font. Bill picked one up. “You made badges?” “I had them printed.” “With glitter?” “Counter-surveillance,” she said. “Parents can’t inspect credentials if they’re temporarily blinded.” A rat poked its head from behind a washing machine, as if hoping to join the briefing, then reconsidered. Bill traced the route with a finger. “So we go in through the side gate, mingle, identify the present pile, and then what? Just pick up thirty boxes and moonwalk out?” “Not moonwalk,” Molly said. “That draws the eye. We use the transfer method.” “The transfer method?” “You carry one present with purpose. Then two. Then four. People assume you are the person in charge of presents because no sane person would steal that openly.” Bill nodded despite himself. “Audacity. The finest camouflage.” “Exactly.” He peered at another section of the map. “What’s this circle labeled ‘juice hazard’?” “Juice table. Sticky perimeter. Avoid.” “And ‘small screaming zone’?” “Bouncy castle. If you get cornered, dive in and vanish among the chaos.” Bill rubbed his chin. “What about the mother?” “The mother is hosting. Distracted, sentimental, and wearing a sash that says BIRTHDAY COMMAND. She’s not the problem.” “The father?” “Operating a grill in weather that makes that objectively foolish. Also not the problem.” Bill lowered his voice. “The grandmother?” Molly’s eyes narrowed with professional respect. “The grandmother is ex-military or Welsh. Possibly both. She watches handbags, knows everyone’s business, and smells fear through fondant. Avoid direct engagement.” Bill exhaled. “Finally, a worthy adversary.” Molly produced a notepad. “Cover identities. I’m Molly from Sparkle Pony Events.” “I refuse to be from Sparkle Pony Events.” “Fine. You’re Bill from Thunder Lizard Leisure.” “That’s worse.” “It sounds masculine and underinsured. It’s perfect.” He looked toward the rain-black window, imagining bunting, shrieking children, and a mountain of brightly wrapped temptation. “You do realize this is our lowest point.” Molly smiled, sharp as a paper cut. “Bill, if we can steal birthday presents from a semi-detached in Croydon while dressed as entertainers, we can do anything.” He slipped on the glitter badge and straightened. “Then let history record that I entered villainy through the side gate.” “Good,” said Molly, rolling up the map. “Now practice looking trustworthy while carrying a gift hamper.” Bill grabbed a detergent box and cradled it tenderly. “Like this?” “No,” said Molly. “Less kidnapper, more coordinator.” He adjusted his expression into cheerful fatigue. She nodded. “Terrible. Convincing. We’re ready.”
