Molly adjusted the pink cone hat on her head and peered through the hedge at the Hendersons' backyard, where forty screaming children were trying to murder a piƱata shaped like a unicorn. Beside her, Bill crouched in a bush that smelled faintly of cat. "Tell me the plan again," he whispered. "You're the balloon guy. I'm the entertainer. Nobody looks twice at either." "I don't know how to make balloon animals." "Nobody does, Bill. Whatever you twist, they'll accept it as a dog." Bill glanced down at his oversized shoes and rainbow suspenders. "Why do I feel like I'm taking the bigger risk?" "Because you're wearing a fake nose. Focus." Across the lawn, the present table sat beneath a striped canopy, heaped with shiny boxes and curling ribbons. It was the biggest haul either of them had ever seen, and it was guarded only by a grandmother asleep in a lawn chair and a toddler eating frosting off a paper plate. Molly had cased the place for two weeks. She knew the birthday girl, Brynn, was turning six and had requested a pony, a trampoline, and, inexplicably, a tax attorney. She knew the cake would be cut at two o'clock, which meant every adult would drift toward the kitchen. She had not planned for the bounce house to be shaped like a castle with a working moat. "Okay," she said, squeezing his shoulder. "At two, you start the Conga line. Every kid follows you, and every parent films it. I roll the wagon to the table, load up, and we're gone in ninety seconds." "What if the Conga line doesn't work?" "Children love a Conga line." "What if they hate me?" "They'll hate you a little. It's fine. Hate is a distraction." The clock struck two. Bill inhaled, stepped out of the hedge, and honked a bicycle horn he had purchased for authenticity. To Molly's astonishment, the children turned as one and surged toward him like a tide. Within seconds he was leading a shrieking, stomping parade around the sprinklers, and Bill, God bless him, looked almost happy. Molly rolled the red wagon across the grass, whistling. She stacked gifts three high, then five, humming "Happy Birthday" for cover. A tiny voice stopped her cold. "You're not a real clown." The toddler stood at her knee, frosting on both cheeks, holding a fork like a tiny sword. "I'm a very real clown," Molly said. "Where's your pony?" Molly paused. "Excuse me?" "Clowns bring ponies." "Sweetheart, I'll bring you a pony if you go and sit by that old lady." The toddler considered this, nodded gravely, and toddled off. Molly heaved the last box into the wagon, threw a tablecloth over the pile, and made for the gate. Ahead of her, Bill was being chased by a hundred small screaming humans and one furious uncle. He caught her eye and mouthed, *Run.* She ran.
