Molly leaned over the sticky kitchen table, unfolding a map of the Pembroke house across the crumbs. "Right. The party's in the back garden at three. Forty-two children, one bouncy castle, and a piƱata shaped like a unicorn." Bill squinted at the blueprint. "And the presents?" "Stacked in the front room, under the window. Mum's been sending me the photos. Look at that pile. It's practically a mountain." "Who needs a mountain of presents? Seven-year-olds can barely hold one at a time." "That's exactly why nobody will notice a few missing." Molly tapped the sketch. "We go in through the side gate during the cake. Everyone's staring at the candles. You grab the big bags, I take the wrapped boxes." Bill scratched his beard. "What about the dog?" "Biscuit? He's harmless. He'll be too busy licking frosting off the clown's shoes." "There's a clown?" "Hired for the afternoon. Balloon animals. I've already got the pass-code for the back door from the cleaner." "Molly, we're robbing a birthday party." "We're *redistributing* a birthday party." She grinned and slid a pair of plastic sunglasses across the table. "Wear these. Nobody suspects a man in a fake moustache." Bill put them on, then frowned. "These are pink." "They're disguises, Bill. Pink is the new black." "And if a kid spots us?" "Then we offer him a juice box and tell him the birthday fairy needs the presents back for maintenance." She folded the map neatly. "Kids believe anything if you sound official enough." "That's a terrible plan." "It's a brilliant plan with a terrible name. Anyway, the loot goes in the van, the van goes to the lock-up, and by Friday we've got enough gift cards to retire to Spain." Bill stared at her. "Do we even like Spain?" "Nobody likes Spain. That's why it's perfect. Nobody looks there." A small voice drifted through the open window. "Mummy, the clown's lost his nose!" Molly froze. Bill's moustache slipped. "Is that a sign?" "It's a distraction," she hissed, snatching the map. "Move. We've got forty-two children to rob before the cake's cut."
