Molly crouched behind the bakery van, watching the townhouse glow with balloons and fairy lights. Through the curtains came shrieks of delight, the thump of tiny feet, and the merciless warbling of a karaoke machine. “That is a lot of joy,” she whispered. Bill adjusted his black gloves and peered around the corner. “Joy means gifts,” he said. “Gifts mean haul.” A clown in sequins lurched past the front door carrying a tray of juice boxes like a royal footman. Bill frowned. “Why is there a clown?” Molly checked her list, which was mostly doodles and one excellent reminder to bring rope. “Because it’s a children’s party, Bill.” He nodded gravely. “Right. Horrible venue choice.” They slipped through the side gate, stepping over a sprinkler shaped like a dinosaur. Inside the kitchen, a mountain of wrapping paper rustled in the heat. Molly pointed to the pile of presents stacked like a tiny department store. “Easy,” she breathed. “We take the lot and vanish before the cake.” Bill rubbed his hands together. “And if anyone asks?” Molly smiled. “We are the aunt and uncle.” From the hall, a child shouted, “The magician’s gone!” Bill froze. Molly listened to the delighted applause outside. “Perfect,” she said. “Everyone’s distracted.” Then the presents began to hum.
