Molly spread the blueprint across the hood of the getaway van—a stolen minivan with a cartoon dolphin decal peeling off the side. Bill leaned over her shoulder, chewing on a licorice whip like it was a cigar, squinting at the crude drawing of the Hendricks' backyard. "Bouncy castle's the main obstacle," Molly said, tapping the paper. "Six-year-olds move fast when there's cake involved." Bill nodded gravely, as if she'd just described a minefield. "And the clown?" "Rented. Leaves at four." They'd been planning this heist for three weeks—longer than they'd spent on the Fairmont jewelry job. The target wasn't diamonds this time. It was presents. Forty-three wrapped boxes sitting under a Paw Patrol banner, victims of a birthday party with criminally lax security. Bill adjusted his fake mustache, the one meant to make him look like "Uncle from out of town." Molly had dressed as a face-painting artist, complete with a kit full of glitter she intended to use as a smoke screen, quite literally. "Remember," she said, snapping the kit shut, "we're not monsters. We leave the birthday kid's gifts." Bill looked wounded. "What kind of thief steals from a six-year-old on their actual birthday?" "The amateur kind," Molly said, and started the van.
