Outside, somewhere, a bouncy castle wheezed. "Final check," Molly whispered. "The presents are still stacked by the piano?" "Twelve boxes, all wrapped in dinosaur paper." "Brilliant. And the Nintendo?" "Top box. It says 'Do not open until Daddy's sober.'" "Lovely. Daddy's in the kitchen with the wine. He's been there since the clown arrived." "Back gate's unlocked, right? And security?" "Gran Dorothy. Seventy-four, bifocals, and a whistle she isn't afraid to use." "Last year she caught Nico stealing a balloon. He still flinches at helium." "Which is why you're going in as a dinosaur." Bill groaned, clutching his foam tail. "Why am I always the dinosaur? Last time a toddler bit my tail." "Because nobody searches a dinosaur, Bill. They're too busy screaming at it." "Fine. Getaway?" "The ice cream van." "The one that plays 'Greensleeves'?" "Yes, obviously." "Molly, that tune brings forty kids running." "Exactly. Forty kids chasing an ice cream van are forty kids not watching the piano. It's basic misdirection." "That's either genius or deeply evil." Molly checked her watch and grinned. "Why not both? Remember, in and out before the singing. Right, let's go. Happy birthday, Oscar." "He's six, Molly. He'll be over it by Monday."
