Bill spread the blueprints across the kitchen table and pinned the corners down with a juice box, a stapler, and a slightly deflated balloon. "Right," he said. "The Henderson residence. Saturday, two o'clock. Little Timmy turns seven." Molly squinted at the paper. "Bill, this is a drawing of a bouncy castle." "It's a schematic." "It's in crayon." "I had to work fast. They've got a surveillance system. Watched me the whole time from the front lawn. Didn't blink once." "That's a garden gnome." "Which is exactly what they want me to think." Bill tapped the drawing. "Now. The presents go on the gift table here, beside the cake. Forty, maybe fifty boxes. Rich neighborhood. We're talking drones, tablets, those little robot dogs that cost more than my car." "Your car cost eleven dollars, Bill. You bought it from a man in a ditch." "And she runs beautifully." He cleared his throat. "Phase one: infiltration. You go in as the entertainment." Molly folded her arms. "What kind of entertainment?" "Clown." "Absolutely not." "Magician, then." "I don't know any magic." "You don't need to know magic. You need to make fifty presents disappear. That's the whole trick, Molly. That's the act." She paused. "Okay, that's actually quite good." "Thank you. I've been reading." Bill pulled a second crayon drawing from his jacket with a flourish. "Phase two: the distraction. At exactly two forty-five, I release the ponies." "What ponies?" "The ponies I'm going to acquire." "From where?" "That's a Phase Zero problem. Don't worry about Phase Zero." Molly pressed her fingers against her temples as though trying to keep her brain from escaping. "Fine. Ponies. Then what?" "While every parent is chasing a Shetland across the lawn, you load the presents into the van." "We don't have a van." "We have a very large pram." "Bill." "It's got excellent suspension. Nobody questions a pram. You could push a grand piano past a policeman in a pram if you hummed a lullaby." "And the kids? Seven-year-olds notice everything. They're like tiny, sticky detectives." "Ah." Bill smiled and placed a paper bag on the table. "That's why we hit them where it hurts." "What's that?" "Sugar. Pure sugar. Two kilos. We spike the cake." "The cake is already sugar, Bill. That's what cake is." "Then we double it. They'll be vibrating too fast to testify." Molly stared at him for a long moment. "There's one flaw." "Name it." "Timmy's mum is Sandra Henderson." The color drained from Bill's face. "Sandra Henderson from the PTA?" "Sandra Henderson who once made a grown man cry for bringing store-bought flapjacks to the bake sale." "She's hosting?" "She's hosting." Bill slowly folded up his crayon schematic. On the table, the balloon let out a long, mournful wheeze and finally gave up. "New plan," he whispered. "We rob a bank." "Much safer," Molly agreed.
