Molly pressed her face against the fence, peering through a knothole at the bouncy castle. "Are you seeing this?" she whispered. "Twelve kids, maybe fifteen. That's a lot of witnesses." Bill adjusted his fake mustache nervously. "Witnesses who can't tell time and believe in the Tooth Fairy." Molly pulled out a crumpled party invitation from her pocket. "According to this, present-opening happens at three o'clock sharp." "So we go in before?" "No, genius. We go in during. Maximum chaos." Bill frowned at the yard full of screaming children. "What's our cover?" "I'm thinking we're the entertainment." Molly grinned wickedly. "You ever do balloon animals?" "I can barely tie my shoes." "Perfect. You'll be terrible, they'll cry, parents will panic, and I'll slip around back to grab the loot." She checked her watch. "We've got twenty minutes." "This is insane. We're robbing children." "We're robbing their rich parents who bought designer toys for a six-year-old's birthday." Molly started walking toward the gate. "Now put on your clown nose." "I'm not wearing the nose, Molly." "Then grab the puppet. We're doing this."
