The warehouse smelled of stale popcorn and older regrets, which suited Molly and Bill just fine since they'd been planning this particular heist for three weeks straight. Spread across the table was a blueprint of the Hendricks residence, complete with a red circle around the backyard where, in exactly forty-eight hours, seventeen unsuspecting seven-year-olds would gather to celebrate the birthday of one Timmy Hendricks and, more importantly, the mountain of presents he was about to receive. Bill traced a finger along the fence line. "Bounce house is our blind spot. Nobody watches a bounce house." Molly nodded, chewing the end of her pencil like it owed her money. She'd spent years lifting jewels from museums and cash from armored trucks, but nothing had prepared her for the tactical nightmare of a clown named Bingo the Magnificent, who apparently doubled as unofficial security. "The clown's the problem," she said. "Clowns are always the problem," Bill agreed grimly, as though recalling some past trauma he wasn't ready to discuss. They studied the map in silence, two career criminals reduced to whispering about balloon animals and juice boxes, plotting the greatest theft of stuffed animals and remote-control cars the suburb of Maple Grove had ever seen.
