Molly studied the birthday party through binoculars, counting balloons, parents, and suspiciously well-wrapped boxes. Bill crouched beside her in a hedge, wearing a tuxedo several sizes too small and the expression of a man who had lost an argument with a laundry basket. “Any guards?” Bill whispered. “Three dads, one grandmother, and a child with a whistle,” Molly said. “The child is the real threat.” Their plan was simple: infiltrate the party disguised as entertainers, distract everyone with a magic show, and escape with the presents before cake. Unfortunately, Bill’s rabbit had escaped during rehearsal and was currently nibbling the hedge. Molly produced two clown wigs from her coat. Bill stared at his. “I refuse to wear that,” he said. “You refused the fake mustache too.” “It made me look French.” “You are French.” “Exactly.” They entered through the garden gate, Molly juggling stolen oranges while Bill attempted to perform ventriloquism with a garden gnome. The children applauded. The adults applauded harder, mostly from confusion. At the crucial moment, Molly slipped toward the gift table. Bill created a diversion by announcing the gnome’s birthday and leading everyone in song. Molly stuffed presents into a laundry sack, but one box began rattling. She froze. A tiny voice inside shouted, “Help!” Molly opened it. A puppy sprang out, licked her nose, and immediately joined the party. The thieves fled with cupcakes instead.
