Rain ticked against the bakery awning while Molly and Bill crouched behind a stack of empty cake boxes. Across the street, the community hall glittered with balloons, paper stars, and the unmistakable promise of unattended presents. “Observe the target,” Molly whispered. “One birthday party, seventeen gift-wrapped boxes, three trays of sandwiches, and a clown who appears to be losing a fight with his own trousers.” Bill raised his binoculars. “That clown is the security.” “He’s wearing enormous shoes.” “Exactly. Nobody can run efficiently in enormous shoes.” Inside, children shrieked around a magician whose rabbit had escaped beneath a table. Parents chatted beside the presents, their attention scattered by sugar, noise, and the aggressive popping of balloons. Molly unfolded a hand-drawn floor plan on the pavement. “We enter through the kitchen, distract the adults with a fake fire alarm, and exit through the lavatory window,” she said. “The lavatory window is painted shut.” “Then we use Plan B.” “What’s Plan B?” “Pretend to be entertainers.” Bill stared at her. “We are criminals, Molly. Not entertainers.” “Bill, you once performed twelve minutes of mime while waiting for a locksmith.” “That was an emergency.” “It involved a hat.” “It was a very persuasive hat.” A gust of wind lifted the floor plan and plastered it against Bill’s face. He peeled it away, revealing the diagram’s final detail: a smiling stick figure labeled “Molly,” falling into a punch bowl. “Your map predicts my humiliation,” he said. “It’s based on experience.” They crossed the street carrying a cardboard box labeled PARTY SUPPLIES. Molly wore a sequined jacket borrowed from a charity shop. Bill wore a waistcoat, a false mustache, and the expression of a man who had just remembered leaving the oven on. At the kitchen door, a little girl blocked their path. She held a plastic sword and regarded them gravely. “Password,” she demanded. Molly crouched. “Cake?” “Wrong.” “Presents?” “Also wrong.” Bill leaned forward. “The password is probably something secret.” The girl nodded. “Correct. You may enter.” Inside, Molly swept toward the gift table while Bill climbed onto a chair and announced, “Ladies, gentlemen, and people currently wearing frosting, prepare for the Amazing Bill!” Nobody looked up. He produced a deck of cards. Unfortunately, the cards were coupons for discounted plumbing. Molly stuffed two presents into the box, then paused. One package trembled. “Bill,” she hissed, “this gift is purring.” “Perhaps it’s an unusually affectionate toy.” The box meowed. A parent turned. Molly smiled brightly and placed the package back. “We’re conducting a surprise quality inspection.” The birthday child approached, clutching a paper crown. “Are you stealing my presents?” Molly froze. Bill dropped the plumbing coupons. “Technically,” he said, “we’re borrowing them for an educational demonstration.” “About crime?” asked the child. “About consequences,” Molly said quickly. She opened the box and removed their loot. Bill sighed, then noticed the sandwich table. “Could we at least steal the sausage rolls?” The child considered this. “Only if you do a magic trick.” Bill performed the card trick with a coupon. It vanished beneath his sleeve and reappeared in his shoe. The children erupted in applause. Molly handed back the presents, accepted two sausage rolls, and whispered, “We’re retiring.” “After lunch?” “After dessert.” The clown applauded too, though he had fallen into a balloon arch and could not escape.
