"Right," said Molly. "Fourteen hundred hours. Bouncy castle goes up, security goes down." "Security being?" "Barbara. Mum of the birthday boy. Wine spritzer at half twelve, second one at one, by two she couldn't identify her own husband in a line-up." "And the presents?" "Trestle table by the patio doors. Stacked like Christmas. I clocked at least eleven, one of them's shaped suspiciously like a Nintendo." "I'm not stealing from a seven-year-old, Molly." "He's turning eight." "Oh, well, in that case." "Don't get moral on me now, Bill, you nicked a defibrillator in March." "That was from a bank. Banks have insurance. Children have *feelings*." "Children have four hundred quid of unopened Lego and no receipt. It's the perfect crime." "What's my cover?" "Entertainer. I got you a costume." "What kind of costume?" "You'll like it." "Molly." "It's a clown." "Absolutely not." "There's a wig." "I'm allergic to wigs." "You're not allergic to wigs, you're allergic to *dignity loss*." "I have a reputation." "You have a caution for stealing a defibrillator." Bill sighed. "Do I have to do balloons?" "Three balloons, one magic trick, then you 'go to your van for props' and I'm out the side gate with the loot." "Fine. But I'm keeping the Nintendo."
