"Bill, whisper, the guard is a plush bear," Molly hissed, crouching by the shrub. "Relax, I brought quiet shoes," Bill said, tapping his sneakers like they were instruments. "Quiet is relative; it squeaked during training in your kitchen," Molly replied. They exchanged silent nods, then crawled toward the living room windows where the party lights blinked like candy. "Target: every present, including the squeaky dinosaur," Bill said. "We can’t leave the parents with nothing," Molly said, then grinned. "We’ll return something harmless—like the wrapping paper roll." Bill fanned a tiny map, which was mostly doodles. "Step one: open the gift pile without waking the birthday kid." Molly slid a suction-cup lock pick from her pocket. "Step two: act like we’re imaginary magicians." "If anyone asks, I’m Bill the Friendly Thief," Bill whispered. "And I’m Molly the Ethical Night Goblin," Molly said, aiming her gloved hand at the doorknob. Inside, laughter swelled; the windows fogged with bubble-machine breath. Molly raised a finger. "On my cue, we snatch the bag, not the child." Bill swallowed. "That’s reassuring," he squeaked. "Absolutely," Molly whispered, "now steal the presents." Bill nodded, clutching tape, and tried not to sneeze too loudly. "No glitter alarms, Molly, okay?"
