Molly crouched behind the hedge, studying the bungalow’s balloons with professional suspicion. Pink streamers drooped from the porch like exhausted flamingos. Through the window, eight children shrieked around a magician whose cape appeared to be made from a tablecloth. Bill adjusted his black wool mask. It had eyeholes, a mouth hole, and, regrettably, a label reading MUM’S GOOD SCARF. “We wait for cake,” Molly whispered. “Why cake?” “Because frosting causes chaos. Tiny fingers, poor coordination, sugar-fueled betrayal.” On the lawn, a pirate piñata swayed above a cluster of foam swords. Bill checked the blueprint: kitchen window, hallway, gift mountain, exit via garden shed. The plan had been elegant before Molly noticed the inflatable unicorn blocking the gate. “We’re stealing presents from children,” Bill muttered. “We’re redistributing luxury plastic to the secondary market.” A boy in a dinosaur costume opened the back door and released a terrier wearing a bow tie. The dog spotted them immediately, barked once, then trotted over carrying a squeaky banana. Molly froze. Bill accepted the banana solemnly. “Bribed?” “Recruitment attempt,” Molly said. Inside, the magician produced a rabbit. Every child screamed with delight except one, who pointed at the hedge. “Are those burglars?” Molly rose, clutching the banana. “No,” she called. “We’re the entertainment.”
