Molly crouched behind the hedge, squinting at the bright balloons bobbing above the back garden. "Right, Bill. Talk me through the plan again." Bill adjusted his fake moustache, which kept drooping at one end. "Simple. We wait for the clown to finish the balloon animals. Then we slip through the side gate, grab every present with a bow on it, and vanish." "Every present?" "Every single one. Those kids won't even notice until they've had their cake." Molly peered through the gap in the fence. A small boy in a paper crown was jumping on a bouncy castle. "That one's going to notice. He's got his eye on the pile by the patio." "Nobody notices a bouncy castle, Molly. That's the whole point of a bouncy castle." "Fair point." She tugged at the sleeve of her black jumper. "Where did you get this bag, anyway? It's got teddy bears printed on it." "It was the only one left at the charity shop. Look, it's practically invisible." "It is literally a bag covered in teddy bears, Bill." "Okay, it's not invisible. But it's cheap, and we're not exactly cutting costs on this job." Molly sighed. "How many presents do we need?" "Thirty-seven. I counted them through the window this morning." "Thirty-seven? Bill, that's a lot of paper and tape. What if they're all just socks?" "Then we'll have very warm feet and a grudge against the birthday girl." A whistle sounded from inside the house. Molly grabbed his arm. "That's the signal. The clown's doing the sausage dog balloon. Go, go, go!" They scrambled over the low wall and sprinted across the lawn, Bill's moustache finally giving up and flapping onto his cheek. Molly seized the first gift, a box wrapped in glittery pink paper. "Oh, this one's heavy," she whispered. "Probably a puppy." "Bill, don't say that." "Or a very large book." They reached the gate just as a tiny voice shrieked behind them, "Mummy, the presents are walking!" "Run!" Molly hissed, stuffing a teddy-bear bag under her arm. "Keep calm," Bill panted. "We've got this. Probably." "You said probably last time, and we ended up in a ball pit." "That was a different party." Molly pulled the gate shut behind them and grinned. "Right. Where to next?" "Birthday party number two. Same clown, different cake."
