"Okay, so the party starts at two," Molly whispered, unfolding a hand-drawn map onto the car hood. "Who draws a map to a Chuck E. Cheese?" Bill asked. "Professional thieves, Bill. Professional thieves." "We're stealing birthday presents from seven-year-olds." "Allegedly stealing. Stay positive." Bill squinted at the map. "Why is the bouncy castle labeled threat level orange?" "Have you ever tried running through one? You lose thirty seconds minimum. It's a death trap." "What's this circle marked the zone of no return?" "The face painting station. Last job I got turned into a butterfly and couldn't shake it for a week. Very hard to be intimidating as a butterfly." "You've done this before?" "Twice. Christmas and Easter. Very seasonal work." Bill rubbed his temples. "The moral implications are really hitting me right now." "The presents go to a thrift store, Bill. We talked about this." "Did we though?" "Mostly in my head, yes." "So what's the exit strategy?" "We blend in." "How?" "I got you a cape and a little wizard hat." Bill stared at her. "I'm a grown man." "You're a wizard, Bill."
