Molly leaned over the cardboard map spread across the kitchen table. "Right, so the party's at number twelve, Maple Lane. Eight kids, one clown, and a mountain of presents in the front room." Bill cracked his knuckles. "A clown? Molly, I don't do clowns. Clowns are professionals at spotting trouble." "He's a children's entertainer, Bill. Balloon animals. Nothing dangerous." "Balloon animals are a weapon in the wrong hands." Molly ignored him and tapped the map. "The back gate's unlocked. We go in during the cake. Everyone's singing, nobody's watching the presents." "And what do we do with the presents? I'm not carrying a hundred plastic trains down the street." "We're not taking them all. Just the big ones. The wrapped boxes with the shiny bows." "Those are the ones with the bikes inside, Molly. You can't fit a bike in a rucksack." "Then we take the rucksacks and the bikes both. Bill, focus. This is a professional operation." Bill sighed and pulled a crumpled ski mask from his pocket. "Fine. But I'm wearing the penguin mask. The reindeer one gives me hives." "You're not wearing a penguin mask." "It's a very serious penguin mask." Molly pointed at a sketch. "Now, the trickiest bit is the dog. A Labrador called Biscuit, according to the invitation." "Biscuit," Bill repeated flatly. "We're being outwitted by a biscuit." "Biscuit is not going to outwit us. We bring sausages." "Where do we get sausages at this hour?" "The corner shop. Twenty-four hours." "Molly, that shop closes at nine." She paused, then grinned. "Then we use the sausages from the buffet table. Simple." Bill groaned and dropped his head onto the map. "This is the worst heist of my life, and I once tried to steal a bank vault with a shopping trolley." "And it nearly worked." "It ended with me in a canal." "Details." Molly folded the map neatly and slid it into her coat. "Tonight we're in, we're out, and nobody gets hurt. Except maybe the clown's pride." Bill stood, adjusting his penguin mask. "Right. Let's go steal some birthday presents."
