Molly unfolded the crayon-colored floor plan across a café table, flattening it with two sugar packets and a suspiciously sticky spoon. The map showed a suburban bungalow, a garden full of plastic flamingos, and a red X over a room labelled PRESENT MOUNTAIN. “Observe the weaknesses,” she said. “Balloons obscure the security cameras, the parents will be distracted by screaming children, and the host has hidden the gifts in plain sight beneath a banner reading ‘DO NOT TOUCH.’” Bill adjusted his wool cap, despite the fact that it was July and they were indoors. He studied the plan with professional concern. “You’ve drawn the dog as a dragon.” “It’s a Chihuahua named Pickles. Same threat level, smaller saddle.” Outside, rain ticked against the window. Inside, a toddler at the next table hurled a biscuit with the calm precision of a trained artillery officer. Bill watched it fly. “What exactly are we stealing?” he asked. “Because last time you said ‘all the presents,’ and we escaped with fourteen identical toy tractors and a chemistry set that dissolved my socks.” “The whole pile,” Molly said. “Dolls, games, remote-control cars, possibly a telescope. Rich parents buy presents as if affection is measured by battery requirements.” Bill tapped the map. “And the birthday child?” “Occupied by a magician.” “Real magician?” “Children’s magician. His greatest trick is charging two hundred pounds to remove a coin from someone’s ear.” Bill leaned closer. The floor plan smelled faintly of grape soda and criminal ambition. Molly had marked routes in glitter pen: entry through the side gate, retreat through the inflatable castle, rendezvous behind the recycling bins. “We can’t use the bouncy castle,” he said. “I sprained an ankle in one at a christening.” “You landed on a bishop.” “I was pushed by a bishop.” Molly produced two paper party hats from her handbag. One had dinosaurs; the other had a glittery unicorn horn that drooped tragically. “Our disguises,” she announced. Bill stared at them. “I’m forty-six.” “Exactly. Nobody suspects a grown man in a dinosaur hat. They assume emotional damage, not burglary.” The café door opened, letting in a gust of wet air and the sound of a passing ice-cream van. Molly gathered the map before the rain could turn the escape route into papier-mâché. “What’s the timing?” Bill asked. “At three-fifteen, the children begin musical chairs. At three-seventeen, there will be tears. At three-twenty, the parents form a diplomatic committee around whichever child claims the music cheated. We enter then.” “And if Pickles notices us?” Molly smiled, showing the confidence of someone who had once outwitted a museum guard using a tray of sausage rolls. “I’ve prepared a distraction.” From beneath the table, she lifted a sausage the size of a small fire extinguisher. Bill nodded slowly. “That might work on the dog.” “It might work on the parents too.” He put on the dinosaur hat. Its elastic snapped beneath his chin with a sound of quiet surrender. “One more question,” he said. “How do we carry thirty-seven presents without looking suspicious?” Molly opened her coat. Underneath, she wore a giant cardboard costume shaped like a birthday cake. “We become part of the entertainment.” Bill looked at the rain, the map, the sausage, and the woman dressed as dessert. “This,” he said, “is either genius or prison.” Molly placed the unicorn hat on his head. “Those are not mutually exclusive.”
