Rain ticked against the van roof while Molly unfolded a crayon-colored map of the neighborhood. “According to this intelligence,” she whispered, “the birthday party begins at three, the presents are stacked beside the refreshments, and the back gate squeaks in B-flat.” Bill peered at the map. “How did you obtain this intelligence?” “I followed a six-year-old home from the bakery.” “You followed a child?” “Technically, I followed his balloon. The child was attached.” Bill rubbed his chin. “And you’re certain this is the right house?” “The map says, ‘Milo’s party, no grown-ups except Trevor’s dad, who falls asleep standing up.’ That’s either useful reconnaissance or a very strange hostage note.” A gust rattled the van. Somewhere beyond the hedge, children shrieked with the alarming joy of people who had consumed too much sugar. Bill adjusted his black turtleneck. “Phase One: infiltration. We enter disguised as entertainers.” “Excellent,” Molly said. “You’ll be the magician.” “Why am I the magician?” “Because you already look like a man who has misplaced several rabbits.” “And you?” “I’ll be the clown.” Bill stared at her. “You hate clowns.” “I hate other clowns. I’m delightful.” They crept through the garden, Molly carrying a suitcase of props and Bill carrying a velvet cape that dragged through a puddle. At the gate, it squeaked. “B-flat,” Molly whispered. “It sounds more like a goose being stepped on.” “Music is subjective.” They reached the patio, where a dozen children sat around a table piled with cake. A woman in a paper crown turned. “Who are you?” she asked. Molly sprang forward. “The Magnificent Molly and Slightly Concerning Bill, here to provide complimentary entertainment!” Bill bowed, caught his cape on a chair, and fell into a tray of jelly. The children erupted in applause. “See?” Molly murmured. “They love us.” Bill emerged purple from the waist down. “I’m not sure applause is the same as affection.” Molly opened her suitcase. “Observe! The vanishing handkerchief!” She pulled a red cloth from the case. Attached to it was a string, which ran beneath the present table and around Bill’s ankle. “Now,” she announced, “the presents will vanish!” Bill tugged carefully. One box slid forward, bumped another, and sent a tower of gifts cascading across the patio. A child cheered. “Again!” “Improvisation,” Molly said. Bill scooped up a wrapped dinosaur. “We have the loot.” The birthday boy marched over, clutching a plastic crown. “Those are mine.” Molly froze. “Bill, what’s our policy on witnesses?” “Usually, we distract them.” “With what?” He held up the dinosaur. “A present?” The boy frowned. “That’s my present.” “Right,” Bill said. “Excellent security.” Molly sighed and knelt. “Listen, Milo. We’re thieves, but only in the professional sense. We steal things, then discover they’re emotionally complicated.” “Are you going to steal my presents?” “Not anymore.” Bill looked disappointed. “We could steal the cake.” Molly considered the enormous chocolate centerpiece. “That’s not a heist. That’s lunch.” They returned every gift, performed three magic tricks, and accidentally made Bill’s trousers disappear behind a curtain. As they fled, the birthday boy shouted, “Come back next year!” Molly waved. “Only if the cake is better guarded!” Bill hobbled after her. “We’re thieves, Molly. We should have stolen something.” “We did.” “What?” She held up a party hat. “Evidence.” “That says ‘Birthday Boy.’” “Then we’ve stolen an identity.” Behind them, the children cheered again, and Bill decided applause might, after all, be affection.
