“Bill, confirm the target.” “The birthday party?” “The children’s birthday party. We steal the presents, not the cupcakes.” “I was planning to steal both.” “Focus. How do we get inside?” “Disguises. I’ll be the magician.” “You can’t do magic.” “I can make a wallet disappear.” “Whose wallet?” “Usually mine, eventually.” “And me?” “You’re the clown.” “I refuse.” “Fine. Be the balloon artist.” “I can’t make balloon animals.” “You can make balloon mistakes. Very artistic.” “What’s security?” “A six-year-old with a whistle.” “Dangerous?” “Only to eardrums.” “Any adults?” “Three. One distracted by the cake, one taking photographs, and one wearing a paper crown.” “The crown means authority.” “It says ‘Birthday Princess.’” “Still intimidating.” “What’s the escape route?” “Through the kitchen, out the side gate, over the hedge.” “Then where do we stash the presents?” “In the getaway van.” “We don’t have a van.” “We have a shopping trolley.” “That’s not a getaway vehicle.” “It has one squeaky wheel. Children will assume it’s entertainment.” “Molly, this plan is flawless.” “Your last flawless plan involved robbing a pet shop.” “We got away with a hamster.” “We returned it.” “Eventually.” “Right. At noon, we enter, perform, collect presents, and leave.” “What if someone asks for a magic trick?” “I’ll pull a rabbit from my hat.” “Do you have a rabbit?” “No.” “Then pull out the cupcakes.” “Finally, a plan with vision.”
