Molly spread the blueprint across the kitchen table, pinning its corners with four suspiciously heavy cupcakes. “According to this,” she whispered, “the presents are stacked beneath the balloon arch.” Bill squinted at the drawing. “Is that the living room or the cake?” “The living room. The cake is marked with frosting.” “Why does the cake have a security perimeter?” “Because it’s guarded by aunts.” Outside, rain tapped the windows. Inside, Molly and Bill wore black turtlenecks, rubber-soled shoes, and expressions of professional seriousness. Bill’s seriousness was weakened by a paper crown that read BIRTHDAY KING. Molly pointed to the plan. “We enter through the side gate at nineteen hundred hours.” “The invitation says seven.” “Exactly. Nobody suspects criminals who arrive on time.” “We have an invitation?” Molly produced two brightly colored cards. “I forged them.” Bill read his. “It says, ‘Happy birthday, Trevor! Love, Grandma.’” “You’re Trevor.” “I’m thirty-six.” “Trevor is a flexible identity.” The plan seemed simple. They would slip into the children’s party, locate the gift table, fill their duffel bags, and leave before anyone noticed. Molly had prepared disguises, coded signals, and a small grappling hook. Bill had prepared three napkins and an appetite. At seven, they approached the house. A banner sagged over the porch: HAPPY BIRTHDAY, TREVOR! Beneath it, a dozen children shrieked around a magician whose rabbit appeared to be judging him. “Remember,” Molly murmured, “we’re cousins.” “Which cousins?” “Distant ones.” “How distant?” “Emotionally, preferably.” A woman opened the door. “You must be Trevor’s relatives!” Molly smiled. “Absolutely.” Bill nodded. “We share several ancestors.” “Wonderful! Put your coats upstairs and join the party.” They entered beneath a barrage of balloons. Molly scanned the room. The presents sat in plain sight, wrapped in glittering paper. Between them and freedom stood a birthday clown, a chocolate fountain, and three children armed with plastic swords. “Phase one,” Molly whispered. “Blend in.” “How?” “Act natural.” Bill grabbed a paper plate and approached the cake. Molly drifted toward the presents, pretending to admire a papier-mâché dinosaur. A little girl blocked her path. “Are you a burglar?” Molly froze. “No.” “You’re wearing black.” “So is the magician.” “He’s a magician.” “I’m also a magician.” “Show me.” Molly reached into her pocket and produced the grappling hook. The girl stared. “That’s not magic.” “It is if you don’t know how it works.” Meanwhile, Bill returned with six cupcakes balanced on his plate. “We have a problem,” he whispered. “The children are guarding the presents.” Molly watched as two boys formed a defensive line. “Then we use the contingency.” “What contingency?” “You distract them.” “With what?” She pointed toward the cake. “Your singing.” Bill went pale. “That’s cruel.” “Crime requires sacrifice.” Bill climbed onto a chair and clapped his hands. “Everyone, gather round! I’m going to sing!” The children groaned, but curiosity overcame resistance. Bill launched into a wildly inaccurate rendition of “Happy Birthday,” changing keys every three words. Adults covered their ears. The clown fled behind a curtain. Molly seized the moment. She grabbed the largest present, then another, and shoved both into the duffel bag. A child tugged her sleeve. “Are you stealing those?” Molly considered lying, but the child’s expression was devastatingly perceptive. “Borrowing,” she said. “For how long?” “Until your parents stop buying such excellent wrapping paper.” Bill finished the song. There was stunned silence. Then the children applauded. Molly stared. “Why are they clapping?” Bill beamed. “I think they liked it.” “Impossible.” The birthday boy approached, holding a small package. “You can have this one.” Molly opened it cautiously. Inside was a toy magnifying glass. “For solving mysteries,” Trevor explained. Bill leaned close. “We’ve been made.” Molly looked at the children, the presents, and the enormous cake. “New plan,” she whispered. “We steal nothing.” Bill nodded solemnly. “Can we still take cupcakes?” “Obviously. We’re criminals, not monsters.”
