Molly unfolded the blueprint beneath the flickering laundromat sign. “The fortress is called Rainbow Castle?” “Children’s party venue,” Bill whispered. “Guarded by balloons, a suspicious clown, and possibly a grandmother with reflexes.” “Our target?” “Every wrapped present in the building.” Molly tapped the map. “We enter through the cake-delivery door, cross the jungle gym, and hide inside the giant cardboard dinosaur.” “Brilliant. What’s the dinosaur’s name?” “Reginald.” “Of course it is.” A burst of shrieking laughter drifted from the nearby hall. Bill adjusted his tiny backpack. “I’m concerned about the children.” “They’re seven. They fear nothing and respect no laws.” “Exactly my concern.” Molly handed him a paper crown. “Disguise.” Bill stared at it. “This says Birthday King.” “Then act royal.” “I demand a pony.” “Later. Tonight, we steal treasure.” They slipped through the delivery entrance, where a sign warned, NO ADULTS EXCEPT STAFF. Inside, glitter clung to every surface like evidence with ambition. Molly crouched behind a tower of juice boxes. “Phase one complete,” she murmured. A little girl appeared, holding a plastic sword. “Are you pirates?” Bill bowed. “Worse. Tax collectors.” The girl considered this. “Can you make balloon animals?” “Absolutely,” Molly said. Ten minutes later, the thieves were surrounded by children, twisting balloons into dogs. The presents remained untouched, but Bill had acquired three cupcakes and a reputation as the funniest king in town.
