Molly and Bill crouched behind the village hall bins, peering through a hedge at a jungle of balloons, banners, and sugar-frenzied children ricocheting beneath a hand-painted sign that read HAPPY SIXTH BIRTHDAY, OSCAR, as if the exclamation mark itself had eaten three cupcakes. “This,” whispered Molly, adjusting the caterpillar-green balaclava she insisted was festive camouflage, “is either our stupidest plan or our finest hour.” “Why choose?” said Bill, whose clown-sized shoes squeaked every time he shifted. “History loves confidence, and children never guard loot; they just hug it, briefly, then get distracted by cake.” The presents sat in a glorious heap by the stage, wrapped in dinosaurs, rockets, and one suspiciously adult sheet of beige paper that made Molly think some relative had brought socks and shame. “Entry routes,” Molly said. “Front door is parents, side gate is bouncy castle traffic, kitchen window is caterers, and the rear fire exit is blocked by a magician who looks like he files taxes with rabbits.” “Magicians are union men,” Bill murmured. “Never cross one. They can produce handcuffs from nostrils.” A woman in a sequined cardigan marched past the windows carrying a tray of orange squash like a field nurse in a war against upholstery. “Who’s that?” Bill asked. “Party aunt,” said Molly. “Every operation has one. Sharp eyes, practical shoes, no visible joy. If she suspects us, we’ll be gift-wrapped in under a minute.” Bill produced a folded map of the hall that looked less stolen from council archives than angrily sketched on the back of a pizza leaflet. “Observe,” he said. “At fourteen hundred, children arrive. At fourteen ten, they scream. At fourteen twenty, face-painting causes a queue collapse. At fourteen thirty, cake. That’s our golden window: while every adult negotiates icing, we sweep the pile, out the fire exit, into the van, and gone.” “And disguises?” Molly asked. Bill opened his bag with the solemnity of a surgeon and revealed two helium balloons, three paper hats, and matching badges that said FUN STAFF. “Invisible authority,” he said. “People trust a badge and a panicked expression.” Molly stared at the badges, then at Bill, then at the inflatable castle where a tiny pirate was bouncing with the expression of a man auditing revenge. “I hate how much I respect that,” she said. “Fine. We go in as entertainment assistants, moan about the schedule, collect the presents for a mysterious treasure hunt, and leave before anyone notices little Poppy has painted the dog blue again.” “Brilliant,” said Bill. “And if we’re challenged, I cry and say the clown quit. Adults fear replacing clowns more than burglary, taxes, and mild fire.” They bumped fists, adjusted their paper hats, and slipped from the bins with the brisk, fraudulent confidence of people who had once stolen a lawn flamingo by pretending to inspect it. Inside, the children roared for cake, the aunt scanned for weakness, and the mountain of presents gleamed under lights like treasure guarded by jam, noise, and absolutely no common sense.
