Molly squinted at the balloon-covered house. "You're sure about this?" "Positive. The kid's loaded. Birthday haul's gonna be massive." "Bill, it's a six-year-old's party." "Exactly! No security, just some tired parents and sugar-crashed kids." "What's the plan?" "We go in through the bouncy castle. I deflate it from the inside, create a distraction." "That's your plan? A bouncy castle?" "You got better?" "Yeah. We dress as clowns. Walk right in." "I hate clowns." "You hate everything." "Fair point. But clowns?" "Nobody questions a clown at a kid's party. We juggle, make some balloon animals, grab the loot." "I can't juggle." "You can't do lots of things. Hasn't stopped you before." "What about the getaway?" "Ice cream truck. I know a guy." "You know a guy with an ice cream truck?" "Don't judge my connections." "Fine. But I'm not wearing the big shoes." "Deal." "And if this goes south—" "When has anything we've done ever gone south?" They stared at each other. "Don't answer that."
