Molly spread the blueprints across the sticky diner table, nearly knocking over Bill's milkshake. "Target is Tyler Pemberton's seventh birthday," she said. "Saturday, fourteen hundred hours. Bounce house in the backyard, clown on the patio, piƱata at fifteen hundred sharp." Bill squinted at the layout. "What's our way in?" "Chimney." "It's July, Molly." "Fine. The dog door. You're going first." "Why me?" "Because I outrank you, and because you fit." Bill slurped his milkshake aggressively. "That's profiling. What about the parents?" "Distraction team. I hired a magician." "You hired a magician?" "Guy named Mysterio. Twelve bucks an hour. He pulls scarves from places scarves shouldn't come from." "And the kids?" "Cake will be laced." Bill dropped his spoon. "Molly, no." "With extra frosting, Bill. Relax. They'll be in a sugar coma. We grab the loot pile, out the back, into the van by fifteen-thirty." "What kind of presents are we even expecting?" "LEGO sets. Nintendo Switch. Possibly a pony." "A pony won't fit in the van." "Then you ride it home." Bill stared at her for a long moment. "I've always wanted a pony." "I know, Bill. I know."
