Molly leaned against the van and whispered, "So we're really doing this?" "Absolutely. Kids get insane presents these days. iPads, gaming systems, designer sneakers." "Bill, it's a six-year-old's birthday party." "Exactly! Rich parents overcompensate. I've done my research." "Your research was watching the house from this creepy van for three hours." "Intelligence gathering! Look, the parents hired a magician. That's our window." "During the magic show?" "Everyone's distracted. We slip in through the back, grab the loot, we're gone in ninety seconds." "What if someone sees us?" "We're wearing these." Bill held up two clown noses. "You cannot be serious." "We'll blend right in! It's a kids party. Probably already has clowns." "The magician isn't a clown, Bill." "Close enough. Entertainment is entertainment." "I'm starting to regret partnering with you." "You said that about the dog show heist and we made three grand." "We stole purebred puppies, Bill. I still have nightmares." "But profitable nightmares. Now put on your nose. The magician just arrived." "I hate you so much right now." "You'll thank me later. Let's go."
