Molly peered around the corner at the bouncy castle deflating in the backyard. "This is your big score? A six-year-old's birthday party?" Bill adjusted his fake mustache. "Trust me, these suburban parents go overboard. I'm talking iPads, designer sneakers, probably a pony." "A pony?" "Metaphorically speaking." Molly watched a clown juggle flaming batons near the gift table. "There's a professional entertainer. This complicates things." "That's why I brought these." Bill pulled two red foam noses from his pocket. "Absolutely not." "We blend in as clown assistants, grab the haul during cake time, exit through the hedge. Simple." Molly sighed, snatching a nose. "If we get caught robbing children, I'm testifying against you." "That hurts, partner." They crept toward the party, dodging a sprinkler and three screaming kids hopped up on juice boxes. The gift table sparkled with expensive wrapping paper. "On three," Bill whispered. "One, two—" A small girl tugged Molly's sleeve. "Can you make a balloon animal?" Molly froze. Bill grinned. "She'd love to, sweetheart. Wouldn't you, Giggles?" Molly's eye twitched. "Absolutely thrilled."
