Rain drummed on the bakery awning while Molly unfolded a crumpled map across a barrel. Bill leaned over it, wearing a purple party hat he had found in a gutter. “Stop looking so pleased with yourself,” Molly said. “You look like a criminal who has just lost a bet.” “I am a criminal who has just won a hat.” “It says Birthday Princess.” “Titles are titles.” Molly tapped the map. “The party is in the upstairs function room. Presents are stacked beside the cake. We go in, collect everything, and leave before anyone notices.” “Excellent. What’s the disguise?” “We’re entertainers.” Bill blinked. “Entertainers?” “I told the bakery we’re the emergency magic act.” “You can’t do magic.” “I can make valuables disappear.” “That’s not magic. That’s theft.” “Exactly. The children won’t know the difference.” Bill inspected the purple hat. “What do I perform?” “Juggling.” “I can’t juggle.” “You can juggle three things.” “Name three things.” Molly pointed at him. “Your hat, your dignity, and this plan.” Bill considered that. “My dignity is already missing.” “Then you’re halfway trained.” They climbed the fire escape, with Molly carrying an empty sack and Bill carrying a rubber chicken. At the landing, music thumped above them: cheerful, shrill, and impossible to escape. Bill whispered, “Why the chicken?” “Distraction.” “What does it do?” Molly squeezed it. The chicken emitted a strangled squeak. “Wonderful,” Bill said. “The sound of a goose being arrested.” Inside, the hallway smelled of frosting and balloons. A hand-painted sign read: WELCOME, MILO! PLEASE DON’T TOUCH THE PRESENTS. Bill stared at it. “That feels personal.” “It’s addressed to children. We’re adults.” “Technically.” Molly eased open the door. Beyond it, a dozen children were playing musical statues while an exhausted clown waved a tambourine. The presents formed a glittering mountain beneath a banner. Bill whispered, “There must be a fortune in there.” Molly squinted. “That one is shaped like a toaster.” “Luxury toaster.” “And that one is clearly socks.” “Designer socks.” Molly nudged him forward. “Smile.” They entered. The clown stopped mid-tambourine shake. Molly threw her arms wide. “Surprise! Emergency magic!” The children cheered. Bill dropped the sack. Molly hissed, “Pick it up.” “I’m making an entrance.” “You’re making a noise.” He snatched it up and bowed. “I’m Bill, the Amazing Gift Gobbler!” A girl in a cardboard crown pointed at him. “You’re wearing my dad’s slippers.” Bill looked down. “Borrowed footwear is part of the act.” Molly began gathering presents. “Observe! The ancient art of rapid relocation!” “Are you stealing those?” a boy asked. “Borrowing,” Molly said. “For how long?” “Indefinitely.” Bill opened a box. “Molly, this is a puzzle.” “Put it in the sack.” “It’s already assembled.” “Then it’s a very efficient present.” The clown advanced, brandishing a balloon animal. Molly whispered, “Plan B.” “What’s Plan B?” “Give everything back.” “That’s not a plan. That’s surrender.” “It’s a tactical reversal.” She shoved the sack toward the children. “Good news! The magic trick is that your presents return!” The children roared. Bill bowed as the clown tied a balloon crown around his head. Outside, Molly sighed. “We stole nothing.” Bill adjusted his party hat. “Not true. I stole three cupcakes.” “You ate three cupcakes.” “Then I stole them permanently.”
