The blueprints were drawn on the back of a place mat in three colors of crayon, because the diner had run out of pens and Molly had run out of patience. "That's the bouncy castle," she said, tapping a purple blob. "That's the piƱata. And that, Bill, is our exit." Bill leaned in, squinting at a green scribble that might have been a hedge or a very large dog. He had been a professional for nineteen years. He had cracked a safe in Antwerp with nothing but a stethoscope and a head cold. He was now being briefed on a job involving a bouncy castle. "Explain to me again," he said, "why we are robbing a seven-year-old." "We're not robbing a seven-year-old. We're robbing the *guests* of a seven-year-old, which is entirely different, morally speaking, and also the guests are the children of the four wealthiest families in the county." Molly stole a triangle of his toast. "Tabitha Pemberton-Voss. Her father imports marble. Last year, a child gave her a pony. Wrapped." "How do you wrap a pony?" "Badly. That's not the point." The point, she explained through a mouthful of toast, was the present table. Every gift arrived unopened and was stacked in the conservatory, unguarded, while thirty-one children were funneled into the garden for ninety minutes of organized activities by a woman named Fiona who ran her entertainments like a Prussian field marshal. Ninety minutes. Two adults. One wheelbarrow, disguised, Molly said, as a wheelbarrow. Bill set down his coffee. "And the parents?" "Drinking. Loudly. In the marquee. They've hired a man to make cocktails out of gin and something called elderflower cordial, and by two o'clock they will not be able to identify their own children, let alone us." "Us being." "You're the magician." Molly slid a photograph across the table: a gaunt man in a plum waistcoat, mid-flourish, doves erupting from a hat with visible reluctance. "Marvo the Mysterious. Cancelled this morning. Food poisoning. Prawns." "You poisoned a children's entertainer." "I bought him prawns. What he did with them was his own business." She produced the plum waistcoat from a carrier bag, and Bill regarded it the way a man regards a diagnosis. "You go in the front. You do fifteen minutes of tricks, badly, so nobody asks for more. Then you tell them the finale requires absolute silence and a closed conservatory door." "And you?" "I'm the pony girl. Nobody questions a woman leading a pony. I come round the side, load the barrow, walk out through the tradesmen's gate at half past three whistling something wholesome." Bill picked up the waistcoat. It smelled faintly of prawns already, which he chose not to investigate. Nineteen years, he thought. Antwerp. The stethoscope. The head cold. "What's my magician's name?" "Bilbonzo." "Absolutely not." "Bilbonzo the Astounding." "Molly." "It's on the poster already," she said, standing, and dropped a five-pound note on the table for a bill of eleven pounds forty. "Wear the hat. Children love a hat." Bill wore the hat. It fit, which he found the most upsetting part of the entire enterprise.
