Molly unrolled the birthday invitation across the café table as if it were a treasure map. It was pink, glittery, and had a cartoon dinosaur wearing a crown. Bill squinted. “That dinosaur looks judgmental.” “That dinosaur is guarding thirty-seven wrapped presents,” Molly said. “Possibly more, if the grandparents are generous.” Bill leaned closer, knocking over the sugar bowl with his elbow. “Are we sure about this? Children’s parties are unpredictable. Last time, one bit me.” “You were dressed as a piñata.” “It was a tactical disguise.” “It was a cardboard donkey with leg holes,” Molly said. Rain tapped the café window. Across the street, balloons bobbed on the gate of Number 14, where the party would begin in exactly one hour. Molly had circled the time in red crayon because it was the only writing implement she’d found in Bill’s glove compartment. Bill picked up the invitation and read aloud. “Princess Dinosaur Adventure Party. Games, cake, magic show, presents. RSVP to Megan’s mum.” “Megan’s mum,” Molly said, “has made one crucial error.” “Trusting society?” “Hiring entertainment from a company with terrible bookkeeping. I rang them. The magician cancelled.” Bill’s eyes widened. “You rang them?” “I rang them as Mrs. Sprinkles from Sparkle Wand Events.” “Your criminal gift is admin.” “My criminal gift is confidence,” Molly said. “We arrive as replacement entertainment, distract the small people with wonder, and exit with the presents.” Bill frowned. “When you say wonder, do you mean actual magic?” “I mean you in a cape shouting, ‘Look over there!’” “That’s not magic. That’s panic with sleeves.” Molly tapped the invitation. “Children don’t know the difference.” “They absolutely do,” Bill said. “Children are small detectives with jam on their hands.” Molly opened her handbag and produced two fake moustaches, a rubber chicken, and a wand that squeaked when bent. Bill stared. “Why do we need moustaches?” “For authority.” “We’re pretending to be magicians, not French burglars.” “Fine, no moustaches. But you’re carrying the chicken.” Bill lifted it by the neck. It gave a melancholy squeak. “I feel we’re disrespecting the craft.” “The craft of stealing birthday presents?” “The craft of theatre,” Bill said. “If I’m going to be booed by six-year-olds, I want rehearsal.” Molly glanced at the house again. A delivery van pulled up, and a man unloaded a stack of bright parcels wrapped in rockets, unicorns, and foil stars. “There,” she whispered. “The haul.” Bill swallowed. “That’s a lot of presents.” “That’s a lot of opportunity.” “That’s a lot of angry parents if we’re caught.” Molly smiled. “We won’t be caught.” Bill looked at her. “You always say that right before we hide in a laundry basket.” “That was once.” “Twice. The second basket had a cat.” “It was a professional risk.” Bill picked a sugar cube from his sleeve. “What’s the escape plan?” Molly paused. Bill groaned. “You don’t have one.” “I have several possible exits.” “Name one.” “The front door.” “That’s not an escape plan. That’s architecture.” Molly gathered the props into her bag. “Listen. We go in cheerful. You make balloon animals.” “I can make a balloon worm.” “Excellent. A classic.” “It’s just a balloon.” “Then I announce a grand present-counting trick. The children close their eyes—” “No child closes their eyes when told to. They open them wider.” “Then you release the chicken.” Bill squeezed it. Squeak. Molly nodded. “Chaos.” Bill sat back, considering. “What about cake?” “What about it?” “If there’s chocolate cake, we may need to adjust the schedule.” “We are not delaying a heist for cake.” “That is the sort of rigid thinking that ruins morale.” Molly stood and pulled on her purple coat. “Come on, Professor Worm. Destiny awaits.” Bill rose reluctantly, tucking the rubber chicken under one arm. “If anyone asks, I’m the assistant.” “You’re the magician.” “I’m the assistant with concerns.” They stepped out into the rain and crossed toward the balloon-covered gate. From inside the house came shrieks, laughter, and the unmistakable roar of a dozen children pretending to be dinosaurs. Bill stopped dead. Molly looked back. “What now?” He pointed at the invitation. “It says fancy dress encouraged.” “So?” “So if we enter without costumes, we’ll stand out.” Molly stared at his damp coat, then at the rubber chicken, then at the glittering dinosaur on the invitation. Five minutes later, they approached the front door wearing two emergency café tablecloths as capes and paper napkins taped to their heads as horns. Bill sighed. “I miss bank jobs.” Molly rang the bell. “Smile. We’re professionals.” The door opened onto thunderous cheering from inside. Bill whispered, “If they offer cake, I’m taking it as hazard pay.”
