"Right," said Molly. "The Hargreaves party. Saturday. Fourteen children." "Fourteen?" "Fourteen, Bill." "That's a lot of children." "It's a manageable number of children." "For what?" "For stealing from." Bill set down his tea. "Molly, they're eight." "Nine, some of them. And their presents are worth four hundred quid, minimum. Have you seen what parents buy now? Tablets. Actual tablets, for children who still eat glue." "I ate glue." "You still eat glue, Bill, that's not the point." "The point is it's Christmas-adjacent thievery. It's got a whiff about it." "It's June." "Then it's worse. There's no season for it." Molly unfolded a napkin covered in biro. "Here's the garden. Here's the bouncy castle. Here's you, in a costume." "What costume?" "Clown." "Absolutely not." "Magician, then." "Better." "You do twenty minutes of card tricks, they all watch you, I go in through the utility room, out the side gate with a bin bag full of Lego." "I only know one card trick." "Do it slowly." "And the presents? Fourteen children notice fourteen missing presents, Molly." "By then we're in Dover." Bill considered this. "Do magicians get cake?" "Magicians get cake." "Then I'm in," said Bill, "but I'm not doing balloons."
