Molly spread the blueprints across the hood of the van, pinning one corner with a thermos and the other with Bill's elbow. "That's not a blueprint," Bill said. "That's a birthday invitation." "It's a map, Bill. It has a map on the back." She tapped a crayon arrow. "See? 'Park by the big tree, come around to the bouncy castle.' They've told us exactly where the security is." Bill squinted. Someone had drawn a dinosaur wearing a party hat next to the words TIMMY IS SEVEN!!! The exclamation points had been gone over so many times the paper had torn. Twenty years in the business, Molly thought. Banks, jewelers, one regrettable museum. And now this. But the jewelry trade had dried up, the museums had installed lasers, and a seven-year-old in the suburbs had forty-three RSVPs. She had counted. Forty-three guests, each carrying a wrapped box. That was a haul. "Walk me through it again," Bill said, which was what he said whenever he hadn't been listening the first time. She sighed and unfolded the second sheet, a real diagram, drawn by her, in pen, like a professional. The backyard. The gift table. The fence gate. A small circle labeled CLOWN? "Why's the clown got a question mark?" "Because I don't know if there's a clown. Clowns are wild cards. Clowns have seen things. Clowns fight back." Bill nodded gravely. He had been chased by a clown once, in Reno, and did not like to discuss it. The plan was simple, which was how Molly liked them. At two-fifteen, Bill would enter through the side gate in disguise and announce himself as the entertainment. While forty-three children and thirty exhausted parents watched him, Molly would slip behind the hydrangeas, load the gifts into a laundry cart, and roll them out to the van. Six minutes, tops. Nobody watched the gift table during the entertainment. The disguise sat folded on the passenger seat. It was purple and furry and had cost Molly eighty dollars at a costume shop that also sold, inexplicably, bait. "It smells like worms," Bill added. "I have questions about the entertainment part," Bill said. "You're a magician." "I don't know any magic." "You can pick a lock in four seconds. Pick a lock in front of them. Kids love that." "That's not magic, Molly. That's evidence." She considered this. It was, annoyingly, a fair point. She looked at the purple suit, then at Bill, then at the crayon dinosaur, which seemed to be judging her. "Fine," she said. "Can you juggle?" "I can juggle three things." "What three things?" Bill thought for a long moment. "Oranges. Or a phone, a wallet, and keys, but only if they belong to someone else." Molly folded the diagram and tucked it into her jacket. Somewhere across town, a mother was hanging streamers and a boy named Timmy was vibrating with anticipation, and none of them had any idea what was coming. "Buy oranges," she said. "And practice. Timmy deserves a show."
