At midnight, Molly spread a map across the laundromat table. Their target was a birthday party in the community hall, where children would soon leave their presents unattended to watch a magician. Bill studied the route through swimming goggles; his glasses had been confiscated by a parrot. “We enter as clowns, take presents, and vanish before anyone notices the balloon animals are judging us.” “I hate balloons.” Molly tapped the service entrance. Their disguise included mascot heads, a trolley marked HAPPY SNACKS, and Bill’s mustache, which was actually a caterpillar from his coat. The plan: roll in during musical chairs, load the boxes, and escape while everyone blamed the magician. Bill tested the trolley. One wheel squeaked “Happy birthday” in falsetto. Molly called it useful until it repeated the phrase in the caretaker’s voice. She rerouted them away from the kitchen and the singing furniture. At dawn, they reached the hall. Children streamed inside, carrying balloons. Bill froze. Molly shoved him forward beneath her lion head. The host waved them toward the presents, delighted the entertainment had arrived. For a moment, the thieves stood among the loot, undiscovered. Then the magician opened his rabbit’s cage. The rabbit wore a police helmet.
