"Nine kids, one bouncy castle, and a piƱata shaped like a shark," Molly said. "That's the layout." "And the presents?" "Trestle table, back garden, guarded by a grandmother." "Guarded how?" "She's got a folding chair and a look." Bill winced. "I hate a look. What's the plan?" "You go in as the magician." "I don't know any magic." "You know how to make a wallet disappear." "That's not the same audience, Molly. Children heckle." "Then be the clown." "Absolutely not. Clowns get photographed. Do you know how many mums are on that street group chat?" "Fine. You're the balloon man." "Balloon man I can do. Balloon man has gloves, which is forensics sorted, and a big bag, which is transport sorted." Bill paused. "What are you doing while I'm twisting poodles?" "I'm the aunt nobody recognises. I compliment the sponge cake, I say 'hasn't he grown,' and I load the wheelbarrow." "There's a wheelbarrow?" "There's a shed." "Molly, that's beautiful." "One rule, Bill. We don't take the birthday boy's present." "Why not?" "Because I'm a thief, not a monster." Bill nodded slowly. "Which one's his?" "The bike." "The bike's worth two hundred quid." "Bill." "I'm just saying the number out loud."
