The Cake Caper "So we're really doing this?" Bill whispered, adjusting his fake mustache. "The birthday boy has a limited-edition action figure. We need it," Molly said flatly. "We're stealing from a six-year-old's party. When did we hit this low?" "When the fence offered two grand. Now, you go left by the piƱata." "Why left? The presents are right there by the table." "Because Derek's mom is watching the right side. Pay attention, Bill." "Derek's mom? What happened to just watching for security cameras?" "She's scarier than any camera. She once tackled someone for taking extra cupcakes." Bill gulped. "How do we handle her?" "You distract her with questions about her quilting club." "I don't know anything about quilting!" "Exactly. Ask her to explain the difference between a quilt and a blanket. She'll talk for twenty minutes." "This is insane." "You're the one who said we needed a vacation from heist planning. This is relaxing." "Relaxing? We're about to commit grand larceny at a bounce house." "Just grab the blue bag under the table and meet me at the car." "Molly, I think we need to reconsider our life choices." "After the presents, Bill. After."
