Molly studied the mansion through binoculars while Bill balanced on a garden gnome, which was already regretting its life choices. Inside, children shrieked around a mountain of brightly wrapped presents, guarded by balloons, a magician, and one suspiciously muscular clown. “We enter through the cake,” Molly whispered. Bill lowered himself from the gnome. “That sounds sticky.” “It’s a decoy. You distract the clown; I’ll seize the gifts.” “With what?” “Professionalism.” Bill nodded, then immediately tripped over a plastic tricycle and rang its bell. Every child turned toward the window. The muscular clown narrowed his eyes. Molly shoved Bill behind a hedge. “Act natural.” Bill popped up wearing a paper crown. “I am a birthday prince!” The clown charged outside, but stopped when Bill offered him a balloon animal. It was meant to be a dog, though it resembled a distressed intestine. The clown accepted it, visibly confused. Molly slipped through the open patio door and began stuffing presents into a laundry sack. Unfortunately, each box contained a noise maker. One honked, another squealed, and the largest announced, “Congratulations, Gary!” Gary appeared beside her, holding a cupcake. “Are you my present?” he asked. Molly considered the question, then handed him the sack. “Guard this.” By the time Bill returned, the thieves had escaped with three gifts, a balloon intestine, and Gary, who had decided they were his new party entertainers.
