Molly crouched behind the hedge, binoculars pressed to her face. Across the lawn, a bouncy castle shaped like a unicorn wobbled in the breeze. "Okay," she whispered. "Presents are on the table by the piƱata. Twenty-three guests, one clown, zero security." "The clown worries me," Bill said, chewing a carrot stick he'd stolen from a lunch box. "Why?" "Clowns see everything, Molly. They're trained to notice things." "You're afraid of a man in enormous shoes." "I'm afraid of a man who can make a giraffe out of a balloon in four seconds. That's dexterity." Molly lowered the binoculars. "Here's the plan. You distract the parents by asking about the vegan cake. I'll slip in, grab the gifts, and be gone before they finish the birthday song." "Why do I get cake duty?" "Because you look trustworthy. You have the face of a substitute teacher." Bill sighed, straightened his tie, and stood. "If I'm not back in five minutes..." "I'll finish the cake." "Molly!" "Go!" Bill marched across the grass with a confident wave. Somewhere inside the yard, a child shrieked. The unicorn began to deflate slowly, like a tired dream, and the clown turned toward the hedge.
