“Tell me again,” said Bill, peering through the hedge with the grave concentration of a man studying military defenses, “why we’re robbing a six-year-old.” “We are not robbing a six-year-old,” said Molly. “We are intercepting a dense concentration of unsecured luxury goods in festive wrapping.” Bill lowered the binoculars. “That sounded better in your head.” “It sounded excellent in my head. Look at it. Bouncy castle, magician, pony rides. These people have money.” “These people,” Bill muttered, “also have frosting, whistles, and the kind of moral certainty that gets the police called before you can say ‘pass the parcel.’” Molly adjusted the brim of her borrowed sunhat. “Which is why subtlety matters. We go in as entertainers.” Bill looked down at his outfit: rainbow braces, oversized shoes, and a waistcoat patterned with balloons. “You’ve dressed me as a birthday accident.” “You’re a clown’s assistant.” “I look like a clown’s regret.” “You’ll live.” “I may not. There are at least twelve children in there, Molly. Children can smell fear. And face paint.” From the garden beyond the hedge came a shriek of delight, then the thump of music and the amplified voice of a woman saying, “No, Oliver, the piñata is not for sitting on.” Molly smiled. “Chaos. Our greatest ally.” “Cake is our greatest ally,” Bill said. “Chaos is how I lost a van in Croydon.” “You drove it into a canal.” “In my defense, the canal was extremely underlit.” She unfolded a hand-drawn map. “Right. Gift table by the gazebo. Entry point: side gate. Exit point: catering van.” “There’s a catering van?” “There will be if we borrow one.” Bill stared at her. “You planned this around a hypothetical van?” “I planned it around confidence. The van is a detail.” “The van is transport, Molly. Transport is not a detail. Socks are details. A fake moustache is a detail. The van is the van.” Molly tapped the map. “Listen. I distract the adults by claiming the magician is a fraud.” “That won’t be hard. He’s making balloons for children dressed as a wizard. He’s halfway to prison already.” “While they argue,” she went on, “you slip to the gift table, load the sacks, and wheel them out as though you’re part of the entertainment.” Bill blinked. “Sacks?” She opened her tote and produced two large red bags. “Seasonally ambiguous.” “We look like kidnappers from a pantomime.” “We look efficient.” A small boy in a paper crown ran past the gap in the hedge, pursued by a girl holding a plastic cutlass and yelling, “Give back my mermaid!” Bill recoiled. “Savages.” “Future management,” said Molly. “Focus.” “I am focused. I’m focused on the fact that every parent at that party has spent the week telling strangers about gluten and attendance numbers. They notice things.” “Not if we become part of the scenery.” Bill frowned. “I have never once in my life blended into scenery.” “That’s because you insist on commentary.” “And because I’m six foot three.” Molly peeked over the hedge. “The mother’s by the cake. The father’s trying to inflate something that appears to be an arch. They’re vulnerable.” “You said that about the jeweler in Bath.” “And he was vulnerable.” “He was a black belt.” “He was emotionally vulnerable.” Bill rubbed his face. “Suppose I get caught carrying twenty presents out of a child’s garden. What’s my explanation?” “You say, ‘Special delivery for the treasure hunt.’” “And if they ask who sent me?” “Say the pirate.” “There’s a pirate?” “There’s always a pirate at these things.” As if on cue, a man in a striped shirt and eye patch emerged onto the lawn carrying a tray of juice boxes. Bill pointed. “I hate it when you’re right. It makes crime feel organised.” Molly grinned. “Ready?” “No.” “Excellent. Nervous men look authentic.” She straightened his bow tie and handed him one of the sacks. From inside the garden came a roar of children chanting for cake. Bill took a breath. “If I’m trampled, tell the papers I died in pursuit of diamonds.” “I’ll tell them you died serving the balloon economy.” “That is not the legacy I want.” Molly slipped through the side gate. “Smile, Bill.” He followed, lugging the red sack and forcing a manic grin as a child immediately pointed at him and shouted, “Mum, the weird clown’s here!” Bill glanced at Molly. “You see?” Without missing a beat, she beamed at the crowd and cried, “That’s not a clown, darling. That’s the Present Goblin.” The children screamed with delight and surged toward him. Bill went pale. “Molly,” he hissed, backing toward the gift table as a dozen tiny hands reached for his waistcoat, “you could have led with that.”
