Molly unfolded the blueprint across the laundromat’s humming dryer. “The target is Mrs. Pumpernickel’s birthday party. Forty-seven presents, one suspicious hamster, and unlimited frosting.” Bill adjusted his burglar mask, which was decorated with tiny yellow ducks. “Our objective: enter, acquire, escape. No children harmed, no cake wasted.” “Excellent. I’ll disguise myself as a magician.” “You can’t do magic.” “Neither can the magician they hired. He makes a handkerchief disappear, then spends ten minutes looking for it.” Bill studied the map. “I’ll pose as a clown.” “You hate clowns.” “I hate witnesses more.” They crept toward the garden, where balloons bobbed above the fence like cheerful surveillance equipment. Molly produced a grappling hook. Bill whispered, “Why is it pink?” “Stealth is a state of mind.” They climbed over. Inside, children shrieked around a mountain of wrapped gifts. A toddler pointed at Bill. “Clown!” the toddler announced. Bill bowed. “At last, professional recognition.” Molly swept toward the presents, waving a wand. “Behold! The Great Disappearing Birthday Loot!” She tapped the largest box. It vanished beneath her cape. Bill grabbed another. “This one’s heavy.” “It’s probably something valuable.” A woman’s voice boomed behind them. “Wonderful! The entertainers have arrived!” Molly froze. “That wasn’t in the plan.” Bill smiled nervously. “Adaptation is just planning wearing tap shoes.” The children cheered as they were handed balloons, and the thieves accidentally performed until sunset, leaving with only two cupcakes and a coupon.
