"Right, so we go in through the back," said Bill, spreading the hand-drawn map across the table. "That's the bouncy castle, Bill." "The side, then." "That's where the clown is stationed." "There's a clown?" "There's always a clown, Bill." "Fine. The front door." "Brilliant. We'll just walk through forty seven-year-olds and their parents carrying empty sacks." "We bring gift bags. We blend in." "You're fifty three years old." "I have a young face." "You look like a haunted potato." "Molly, focus. We get in, we grab the presents, we're out before they cut the cake." "What kind of presents are we even talking about? Lego? Slime kits?" "The birthday kid is little Freddie Harrington. His dad's a hedge fund manager." "Oh." "The guest list alone has three Hugos and a Tarquin." "So we're talking Nintendo Switches. Remote control Ferraris." "And probably a pony voucher." "There's no such thing as a pony voucher." "Not yet there isn't." Molly stared at him for a long moment. "I want sixty percent." "Fifty five." "The clown, Bill. Sixty." Bill folded the map slowly. "Fine. Sixty."
