Molly crouched behind the hedge, peering through the garden fence. “There are seventeen children, three exhausted adults, one inflatable unicorn, and a man dressed as a penguin.” Bill adjusted his black wool cap. “Excellent. The penguin is our way in.” “You said that about the clown.” “The clown was too emotionally convincing.” “He asked you to make a birthday wish.” “I panicked and wished for a smaller clown.” Molly glanced at the house. Balloons bobbed above the windows, each marked with a glittering number eight. “The presents are stacked in the conservatory. We get in, grab the parcels, and leave before anyone notices.” “Define ‘grab.’” “Lift discreetly.” “Define ‘discreetly.’” “Without shouting, ‘Treasure acquired!’” Bill nodded solemnly. “A demanding operation.” From inside the garden came a shriek, followed by the unmistakable sound of a balloon being sat on. Molly checked her watch. “The magician starts in four minutes. During the rabbit trick, everyone looks toward the hat.” “Except the rabbit.” “Exactly. We slip through the side gate, cross behind the barbecue, enter through the conservatory, and take the presents.” “What if the side gate is locked?” “Then we use the key.” “Where is the key?” “Under the flowerpot.” Bill pointed. “Which flowerpot?” “The one marked ‘spare key.’” “That seems less like security and more like an invitation.” “It’s a children’s party, Bill. The host has already hired a penguin.” A small boy appeared on the other side of the fence, holding a plastic sword. “Are you spies?” Molly froze. “No.” Bill crouched beside her. “We’re birthday consultants.” The boy narrowed his eyes. “Why are you wearing black?” “Because we consult after sunset,” Bill said. “It’s noon.” “We’re very efficient.” The boy considered this. “Can you make a balloon dog?” Bill whispered, “Can you?” “I can make a balloon apology.” The boy grinned. “Come in! The penguin is giving out badges.” Molly grabbed Bill’s sleeve. “Absolutely not. We are not accepting badges.” “Badges establish credentials.” “They establish evidence.” The boy had already unlatched the gate. “I’m Toby. You can be the Surprise Guests.” Molly sighed. “Fine. But we stay focused.” Inside, the party roared around them. A woman in a paper crown carried a tray of sandwiches. The penguin waved. Bill waved back. “Stop waving,” Molly hissed. “He recognized me.” “He’s a man in a costume.” “Recognition is recognition.” The magician tapped his wand against a top hat. “And now, children, watch closely!” “Move,” Molly whispered. They hurried behind the barbecue, where Bill snagged his coat on a string of fairy lights. “Don’t pull,” Molly said. “You’ll bring down the decorations.” “I’m not pulling. I’m negotiating.” The lights flickered. Every child turned. Molly smiled broadly. “Birthday consultants.” “Do a trick!” Toby shouted. Bill shoved his hands into his pockets. “Certainly. Observe.” He produced a rubber chicken, a party whistle, and three wrapped chocolates. Molly stared. “Where did you get those?” “Professional preparation.” The children cheered. The adults applauded. Even the penguin gave a thumbs-up. Molly leaned close. “We’re improvising.” “Your favorite kind of plan.” They reached the conservatory. Presents glittered beneath the table: boxes, bags, ribbons, and one enormous parcel labeled TO MOLLY. Molly blinked. “That’s my name.” Bill lifted it. “A gift from fate.” A voice behind them said, “You found it!” They turned. Toby stood there with the birthday boy. “It’s for you,” the boy said. “Mum said the party needed two more entertainers.” Molly opened the parcel. Inside were two glittery capes. Bill beamed. “Our heist has become a performance.” “And the presents?” Molly asked. The boy pointed to the magician. “He steals those.” Bill lowered his voice. “We’ve been out-heisted by a professional.” Molly put on the cape. “Smile.” “Why?” “The children are watching.” Bill smiled at the penguin. “Treasure acquired.” The penguin applauded.
