Rain ticked against the window of the abandoned pet shop while Molly spread a hand-drawn map across a crate of squeaky toys. The map was labeled BIRTHDAY FORTRESS in purple crayon, with several alarming dragons sketched around the perimeter. Bill leaned over it, wearing a burglar’s mask that had eyeholes in the wrong places. “I still say we should wait until the party’s over,” he whispered. “That’s when the children are most alert,” Molly replied. “Sugar crashes make them unpredictable.” “They’re six.” “Exactly. No criminal is more dangerous than a six-year-old with a frosting-covered plastic sword.” Bill adjusted the mask, which slipped over his nose. “And the presents?” “All stacked beneath the balloon arch. We enter through the kitchen, cross the hallway, distract the parents, and load the loot into the laundry cart.” “Why a laundry cart?” “Because I couldn’t find a getaway vehicle.” Outside, a delivery van hissed to a stop. Molly peered through the blinds. Across the street stood a cheerful house decorated with streamers, paper crowns, and a banner reading HAPPY BIRTHDAY, GRAHAM. A dozen children swarmed the front garden, while a harried woman carried a cake shaped like a dinosaur. Bill studied the scene. “What if Graham has a security system?” “He does. His name is Toby, and he’s wearing a Spider-Man cape.” “His superpower?” “Shrieking.” Molly produced two party hats from her coat. One said PRINCESS. The other said T-REX. “Disguises,” she said. Bill stared at the hats. “You want us to infiltrate a children’s party dressed as children?” “No. I want us to infiltrate as party entertainers.” “Which one am I?” “The dinosaur.” “Why am I always the dinosaur?” “Because you have the emotional range.” They crossed the street beneath a shared umbrella and approached the gate. Molly wore the princess hat, a borrowed pink tutu, and an expression of professional confidence. Bill had added a green tablecloth around his shoulders. He moved like a man being slowly defeated by fabric. At the door, the birthday mother opened it halfway. “Can I help you?” “We’re the emergency entertainment,” Molly announced. “The magician was arrested.” Bill waved one padded hand. “For tax reasons.” The mother blinked. From inside came a thunderous chorus of children shouting, “PIN THE TAIL ON THE DONKEY!” “Oh,” she said. “Come in, I suppose.” Molly swept past her. Bill followed, tripping over the threshold and landing beside a pyramid of presents. The children turned as one. A boy in a cape pointed. “That dinosaur is fake!” Bill rose with dignity. “I am a highly trained professional.” “Prove it!” Bill opened his mouth, but Molly stepped forward and clapped twice. “Ladies and gentlemen, prepare for the greatest magic trick of the afternoon!” She snatched a wrapped box from the pile and held it high. The children gasped. “Now watch carefully,” she said. “This present will disappear.” Bill’s eyes widened. “Molly—” She tossed the box into the laundry cart. “And so will the rest.” The children cheered, assuming this was the entertainment. Parents applauded politely. Bill began hauling gifts while Molly performed increasingly desperate tricks with napkins, balloons, and one confused birthday candle. By the time anyone noticed, the cart was overflowing. Then Toby, the Spider-Man security system, blocked the door. “You can’t leave,” he declared. Molly smiled. “Bill, initiate Plan B.” “What’s Plan B?” “Run.” Bill grabbed the cart. Molly grabbed Bill. Toby grabbed the dinosaur tail. The tail detached instantly. Bill stared at it. “That was structural?” “Budget disguise,” Molly said. They fled into the rain, leaving behind half the presents, the cart, and a roomful of children convinced they had witnessed the world’s greatest magic show.
