The van idled behind the bouncy castle hire company, its headlights switched off for dramatic effect. Molly pressed a pair of binoculars to her eyes and surveyed the backyard of number twelve Maple Lane. Balloons bobbed in the breeze. A clown juggled flaming torches with alarming confidence, and somewhere a child shrieked with joy at the sight of a sugar-coated pony. "Four guards," Bill whispered, tapping a clipboard covered in hand-drawn diagrams. "Two dogs. One grandmother." "Grandmother?" "She's guarding the piƱata." Molly lowered the binoculars with a sigh. Their plan had seemed airtight in the kitchen last night, somewhere between the second bottle of wine and the third moustache doodled on the blueprint. Now it looked considerably less brilliant. Bill adjusted his ski mask, which was pink and printed with cartoon unicorns, and nodded with the confidence of a man who had never once been correct. "Nobody suspects a party crew," he said. Molly glanced down at the matching paper hats they were both wearing, each one bright purple and slightly crooked. She hefted the sack labelled "LOOT" in glitter paint and took a deep breath. "Right. Operation Gift Wrap begins now."
