"Balloons," Molly said. "That's our way in." "Balloons." "You'll be the entertainer. Bobo." "Why Bobo?" "Because Reginald doesn't say 'fun,' Bill, it says 'tax fraud.'" "And what are you, then?" "Bobo's assistant. I hold the sack." "The sack of presents." "The sack of presents." "And nobody finds it suspicious that the clown's assistant is walking out with everything the birthday boy owns?" "They'll be watching you fail to juggle." "I can juggle." "You dropped a grapefruit on my foot in March." "That grapefruit was defective." "Two o'clock, garden gate's unlocked, mother's name is Fiona, and the child is called Tarquin." "Tarquin." "Turning seven." "He'll have a bouncy castle, mark my words. Rich ones always do." "So we go in through the bouncy castle." "You don't go in *through* a bouncy castle, Molly, it's not a tunnel, it's an inflatable—" "Fine. We go past the bouncy castle." "Better." "Then out the gate, into the van, and we're in Dover by supper." "And if a child cries?" "Then you honk your nose and I run faster." Bill sighed and reached for the wig. "Fifteen years of crime," he said, "and I've come to this." "Put the shoes on, Bobo."
