Molly leaned over the cardboard box of plans, squinting at the sketch of a bouncy castle. "Right, Bill. Entry point. The vicarage garden, through the hedge, past the bouncy castle." Bill chewed on a biscuit and frowned. "What's the bouncy castle for?" "Security, obviously. Nobody gets past a bouncy castle." "Molly, it's a bouncy castle. It's for children. It's full of toddlers screaming at each other." "Exactly. Nobody's going to notice two grown adults creeping about the edges with sacks." She tapped the map. "We go in at half two, when the clown does the balloon animals. He's always distracted." "The clown scares me," Bill said quietly. "He looked at me last year like he knew about my tax problems." "Ignore the clown. Focus on the presents. There's a table by the patio, piled high with gift bags. Eight of them, at least. I've counted." "How did you count them?" "I walked past with a trolley and pretended to look for my nephew." Bill sighed and pulled a pair of novelty reindeer antlers from his coat pocket. "And these?" "Disguise. We're uncles. Uncles are invisible at children's parties." "I'm not wearing antlers, Molly." "You're wearing antlers, Bill, or I'm telling everyone about the hamster incident." "That was an accident!" "You sat on it." Bill pushed the antlers onto his head with a grumble. "Fine. But if I get caught by a six-year-old with a plastic sword, I'm blaming you." "Deal." Molly rolled up the plans and tucked them into her handbag, which was shaped like a giant cupcake. "Now, the getaway. Dave's parked the van round the corner, engine running." "Dave's got a learner's permit." "Dave's very enthusiastic." Bill peered out the window at the sprawling garden, where a pink banner read HAPPY SEVENTH BIRTHDAY, OLIVER! "Molly, I just noticed something." "What?" "There's a piƱata shaped like a unicorn, and it's wearing a tiny police hat." Molly stared. "Well, that's just rude."
