Molly and Bill crouched behind a hedge outside the community hall, watching a banner flap above the door: HAPPY BIRTHDAY, LEO! Beneath it, children charged in circles while adults carried trays of cupcakes. A mountain of presents occupied the stage. Bill consulted a napkin covered in arrows, none of which pointed in the same direction. “Once we’re inside, we take the presents and leave,” he whispered. “Excellent,” Molly said. “A plan with the elegance of a shopping trolley.” “I’m being practical.” “You’ve drawn a trapdoor.” “That’s the cake table.” Molly peered through the window. A clown was teaching the children to juggle oranges. One orange bounced off a lampshade, and the children applauded as if gravity had performed a magic trick. “How do we get past the adults?” Bill asked. “We could pretend we’re magicians.” “You can’t do magic.” “I can make a wallet disappear.” “Not from someone else’s pocket, Molly.” “That’s a matter of perspective.” Their disguises were a pair of borrowed party hats and Bill’s old tuxedo jacket, which had a streak of mustard down one sleeve. They entered with a cluster of arriving relatives, carrying a gift bag between them. Inside it was a brick, included for what Bill called “authentic heft.” At the door, a woman handed them name tags. Molly wrote “Auntie” on hers. Bill wrote “The Magician,” then crossed it out and wrote “Uncle.” A little boy examined him. “Which one?” “Your uncle,” Bill said. “From where?” Bill glanced at Molly. “The north.” The boy nodded solemnly and ran off, apparently satisfied that the north contained uncles. They edged toward the stage. Bill lifted the first present, a box wrapped in silver paper. A tiny bell jingled inside. “Careful,” Molly murmured. “I am careful.” “You’re holding it upside down.” “I’m carefully holding it upside down.” A child appeared beside them, wearing a cardboard crown. “Are you taking Leo’s presents?” Molly froze. Bill lowered the box. “We’re checking for dangerous toys,” Molly said. “Is that true?” “It’s almost true,” Bill whispered. The child considered this, then pointed at the brick-filled gift bag. “That one looks dangerous.” Before either thief could respond, the clown bounded over and plucked the bag from Bill’s hand. “A surprise for the birthday boy!” he announced, placing it on the gift pile. Bill watched their brick join the presents. “We’ve donated our getaway weight.” “Maybe it’ll be useful,” Molly said. “He can build a shed.” The children began singing. Leo stood before the presents, grinning, while his parents filmed. Molly looked at the wrapped boxes, then at the boy’s bright, expectant face. “New plan,” she whispered. “Steal the cake?” “Help him open everything.” Bill sighed. “That plan has terrible profit margins.” They joined the crowd. Molly handed Leo the silver box. Bill passed out cupcakes. When Leo unwrapped the brick, everyone stared. Bill cleared his throat. “It’s a very sturdy toy.” Leo hugged it. “I’m building a castle!” Molly smiled. Bill eyed the exit, then took another cupcake. For once, the best thing they’d stolen was the chance to leave empty-handed.
