Molly crouched behind the bakery van, eyeing the pyramid of presents outside the community hall. Inside, the children’s party pulsed with music, frosting, and a clown whose shoes looked morally confused. Bill adjusted his fake mustache and smiled like a man about to make a terrible decision beautifully. “Plan is simple,” Molly whispered. “We enter as entertainers, load the gifts onto the trolley, and vanish before anyone notices the magician has disappeared.” Bill tapped the trolley. “I’m the magician?” “You’re whatever keeps you quiet.” He peered through the window. “You really think toddlers won’t notice two suspicious adults with a folding cart and a prayer?” “They’ll be too busy eating cake.” A crash sounded, then applause. Bill nodded. “Cake. Excellent.” “At seven, distract the parents,” Molly said. “Use your card trick.” “I don’t know a card trick.” “Then improvise.” “I hate when you say that. It sounds like a hospital bill.” Molly grinned. “Relax. We’re not robbing children.” “We’re not?” “We’re liberating gifts from an unsafe environment.” Bill straightened his bow tie. “That’s the nicest criminal thing you’ve ever said.” Molly checked her watch. “Ready?” Bill swallowed. “As ready as a man can be when the loot is glittering.” “Excellent,” she said. “Try to look festive.”
