Rain stitched silver lines across the windows of the abandoned laundromat, where Molly and Bill crouched over a hand-drawn map of the neighborhood. The map had been sketched on the back of a pizza menu and was decorated with grease stains, arrows, and one alarming illustration of a dragon. At the center, Molly had circled the community hall in red crayon. “Tonight,” she whispered, “we infiltrate the birthday party, locate the presents, and leave before anyone notices.” Bill peered at the map. “How many presents?” “According to the invitation, twenty-three.” “Twenty-three children?” “Twenty-three presents.” “That seems excessive.” “It’s a seven-year-old’s birthday. Excess is the theme.” The hall stood behind a row of poplar trees, glowing warmly against the wet evening. Balloons bobbed in the windows. A cardboard banner announced HAPPY BIRTHDAY, RUPERT in letters that sagged like tired eyebrows. Through the glass, Molly could see parents balancing paper plates while children ricocheted between tables. Bill adjusted his borrowed chauffeur’s cap. It was much too small and perched on his head like a pastry. “What’s my role again?” he asked. “You’re the magician.” “I don’t know any magic.” “You know how to distract people.” “I once walked into a coat rack and blamed a ghost.” “Exactly. Prepare to astonish.” Molly wore a pink party hat over her black knit cap and carried a cardboard box labeled PROFESSIONAL CLOWN EQUIPMENT. Inside were two rubber chickens, a coil of rope, and a bundle of balloons she had stolen from a florist’s dumpster. Their plan depended on a side door, a confused catering delivery, and Bill’s ability to appear harmless. The first two parts were sound. The third was aspirational. They approached the hall beneath a shared umbrella. At the side entrance, Molly knocked twice, then once. A woman opened the door. “The clown?” Molly smiled. “The clown.” Bill raised one hand. “And assistant magician.” “You’re late.” “We were delayed by a ferocious pigeon,” Bill said. The woman sighed and waved them in. “Put the presents in the storage room. Then entertain the children.” The storage room was already stacked with brightly wrapped boxes, each one labeled with Rupert’s name. Molly’s eyes gleamed. “Beautiful,” she murmured. Bill glanced toward the party. “Remember, we’re taking all of them.” “Obviously.” “Even the enormous one?” “Especially the enormous one.” They began carrying boxes inside, but Molly noticed something troubling. Every gift had a small silver tag attached to it. Rupert’s parents were standing near the cake, watching the storage room through a discreet security monitor. Bill swallowed. “Those tags look electronic.” Molly examined one. “They are.” “So we’re being tracked?” “Only if we remove them.” “Which is generally how stealing works.” From the party room came a burst of laughter, followed by a child shouting, “The magician is here!” Bill straightened his tiny cap. “I have an idea.” “That sentence has never improved a situation.” He grabbed the largest present and marched into the room. “Ladies and gentlemen,” he announced, “behold the disappearing birthday gift!” He tripped over a balloon, vanished behind the cake table, and landed inside a cardboard castle. The children roared with delight. Molly watched the parents laugh, then quietly placed the presents back where she had found them. “New plan,” she said. “We steal the cake.” Bill emerged from the castle wearing a paper crown. “Finally, a plan with dignity.”
