"Right," said Molly. "The target: Tilly Braithwaite, age six. Theme: unicorns." "I've got the van." "You've got a van?" "I've got *access* to a van. Ice cream van. Bit of a queue situation, potentially." "Bill, we're stealing presents, not selling ninety-nines." "That's the genius. Kids come to us. We drive off with the kids' presents while they're distracted by soft-serve." "The presents will be in the house." "Ah." "On a table. Behind a banner that says 'Tilly Is Six.'" "So we go in the back." "There's a bouncy castle in the back." "I love a bouncy castle." "You will not be bouncing." "I might bounce a bit. Professionally. For cover." "Bill." "What's the plan then, brains?" "You're the entertainment. Barry the Balloon Man cancelled this morning." "Barry cancelled? Barry's got a beautiful reputation—" "Barry got a flat tyre because somebody let his tyres down." "That somebody sounds thorough." "You go in with a bag of balloons. You do twenty minutes of twisting. Parents film it, everyone's charmed, nobody watches the present table." "And you?" "I'm Auntie Deborah. Nobody questions an Auntie Deborah." "Can I do the sausage dog?" "You can do the sausage dog." "Molly," said Bill, misty-eyed. "This is why I love working with you."
