Molly tapped the blueprints. "Right, Bill, the score's in the conservatory. Twenty-three presents, and we're taking every last one." "Twenty-three? For one six-year-old?" "Which is why she's spoiled rotten. Our inside woman is Grandma Doris. She's left the back door open." "Doris is a grandma. Grandmas don't do crime." "Doris cheats at bingo, Bill. She's a natural." "So we're breaking in?" "Breaking in is messy. We're strolling in." "And the magician? He's booked for two o'clock." "Cancelled this morning. Which means we're the magicians now." "We don't know any magic, Molly." "We know how to make things vanish. That's basically magic." "Why are we in an ice cream van?" "Nobody suspects an ice cream van." "Everybody suspects an ice cream van. You can hear it from three streets away." "Nobody can say we're sneaking about." "What about the birthday girl? The one who bit the postman?" "Poppy? She's six. Keep your distance, and she'll never notice." A small face appeared at the window, nose pressed to the glass. "Molly, she's here." "Smile, Bill. Be a magician." "She's holding a clipboard and a whistle." "Good afternoon," said Poppy. "Are you the magicians?" "Absolutely, sweetheart." "Then make the presents disappear." "Abracadabra!" "Abra-RUN!"
