Molly adjusted her fake mustache while Bill checked the surveillance photos of the birthday venue. A children's party. They'd stolen from banks, museums, and penthouses, but never this. "So the plan is we go in dressed as clowns?" Bill asked. "Exactly. Nobody suspects clowns," Molly replied, grinning. "Last time someone said that to me, I got hit with a cream pie," Bill muttered. "That was your own fault for eating the props," Molly shot back. "Look, we slip in through the back during the piƱata chaos, grab the gift pile, and vanish." Bill studied the blueprint. "What about the eight-year-old security guard?" "The what now?" Molly's eyebrow raised. "The birthday boy's older brother. Kid's got a walkie-talkie and apparently takes his job very seriously." Molly leaned back in her chair. "You're telling me we need to outsmart a child?" "A motivated child with snacks and territorial instincts," Bill confirmed. They sat in silence, contemplating their career choices. A heist gone wrong in a mansion was one thing. But explaining how they were apprehended by a pre-teen would haunt them forever. "Maybe we rob the movie theater instead?" Bill suggested hopefully.
