Molly crouched behind the hedge, peering at the rainbow balloons bobbing over the garden fence. Bill adjusted his tie, which was already a crime against tailoring. “Tell me again why we’re doing this,” Bill whispered. “Because,” Molly said, “the Finchley children have the largest haul of birthday presents in the district, and we have been badly underemployed.” Bill frowned. “That is not a reason. That is a parish newsletter.” “Focus. We go in as entertainers.” “You can’t juggle.” “I can, if the juggling balls are emotionally supportive.” Bill looked at the party, where a magician was making a rabbit disappear into applause. “So we pose as the act after the magician?” “No. We pose as the emergency backup clowns.” “There’s no such thing.” “There is if you say it confidently.” Bill sighed. “And the presents?” “We borrow them.” “Borrow?” “Forever.” He straightened his gloves. “Molly, this is monstrous.” Molly grinned. “It’s also festive. Besides, who suspects thieves at a party with a bouncy castle?” Bill glanced at the castle. “I do.” “Excellent,” Molly said. “You’re learning.” Then they heard the birthday song begin, and both of them smiled like professionals who had just found a lock made of frosting.
