The blueprints were drawn on the back of a placemat from Ricci's Pizza, which Bill considered a professional touch, since nobody suspects a placemat. He had rendered the bouncy castle as a lopsided trapezoid and labeled it FORTRESS. The piñata was marked with a skull. Molly had been staring at the thing for eleven minutes, her coffee going cold, her faith going colder. "Bill," she said. "Why is the clown circled three times?" "Because the clown is the variable." "The clown is a man named Wendell who does birthdays in Cranston for forty dollars and gas money." "That's what he wants us to think." Molly rubbed her eyes. Outside, a garbage truck groaned past the window and rattled the spoons in the sink. She had done a jewelry exchange in Providence. She had walked out of a bank in Fall River with eleven thousand dollars taped to her shins and a smile on her face like a woman leaving church. Now here she was, twenty-two years into a career, planning the acquisition of approximately forty wrapped gifts belonging to a child named Tucker who was turning seven on Saturday. "Explain the money again," she said. "Rich kid. Rich parents. Rich parents' rich friends." Bill tapped the trapezoid. "Tablets. Gaming consoles. Last year the kid got a pony, Moll. A pony." "We're not stealing a pony." "I'm just establishing the tax bracket." The plan, such as it was, involved a van, two garbage bags, a service gate that the landscaping crew propped open with a brick, and a nine-minute window during which every adult at the party would be watching Wendell twist a balloon giraffe. Bill had timed the giraffe. He had attended two previous engagements undercover, wearing a polo shirt and an expression of aggressive dadness, and he had come away with a napkin full of notes and a slice of cake he claimed was research. Molly found, to her enormous irritation, that the timing worked. "The presents sit on the long table under the awning," Bill said. "Nobody guards them. Nobody's ever guarded them in the history of birthdays. It's the softest target in America." "There will be thirty children." "Children are terrible witnesses. They think everyone is a hundred years old and everyone's car is red." She lit a cigarette she didn't intend to finish and looked at the skull he'd drawn on the piñata, which was the first sign of imagination she'd seen from him in years. The problem wasn't the security. The problem was that somewhere in the sediment of her personality there remained a woman who had once been eight years old at a bowling alley, waiting for a cake, and she could still remember the specific brightness of the wrapping paper. "We leave one," she said. Bill looked up. "What?" "For the kid. We leave one present on the table. The biggest one." "That's a hundred and sixty dollars of merchandise, minimum." "It's a hundred and sixty dollars of not being animals, Bill." He considered this the way a man considers a menu he can't afford, then took out his pen and wrote, in careful block letters at the bottom of the placemat: LEAVE ONE (SENTIMENT).
