The van idled behind the bouncy castle warehouse, headlights off, engine purring like a nervous cat. Molly unrolled a blueprint across the dashboard, pinning the corners with a half-eaten sausage roll and a squeaky rubber duck. "Phase one, the back gate," she whispered. Bill squinted at the paper. Someone had drawn a unicorn over the loading dock. He decided not to ask. From inside the party hall came a shriek of birthday laughter, followed by the wheeze of a bouncy castle losing air. Both thieves flinched in unison. Bill adjusted his ski mask, which had clearly been purchased from a toy shop and had a tiny pompom on top. "Ready?" he asked. "Almost," Molly said, sliding a crayon behind her ear. "Nobody gets hurt. We take presents, not cake." "And the goody bags?" She gave him a look that could curdle milk. "Bill." He sighed and dragged a sack the size of a sofa from under his seat. Lollipops rattled inside like loose teeth. Tiptoeing toward the gate, they slipped past a sleeping clown, a bored dog in a party hat, and a seven-year-old guarding a piƱata with a plastic sword.
