Moonlight pooled on the porch when Molly set her stethoscope to the wall. Bill held a tiny wrench, pretending it was a toy. They stared at the open window, where music thumped like a heartbeat. Tonight’s target: every wrapped gift, no questions asked. “Eight o’clock, they swap candles, and the parents cheer.” “Perfect, I’ll spoof the smart lock while you lift the tree skirt.” “If a clown guard appears, tell him we’re undercover elves.” “Elves don’t steal.” “We only relocate happiness.” “Grab the big ones, then the socks, then the candy cannons.” “Candy cannons are risky.” “Everything is risky, but my magnet gloves are licensed.” “And if the birthday kid catches you, wink, and blame the Easter Bunny.” “I’ll distract him with a balloon sword today.” “Go time, this second. After eight minutes, the grandparents start the do-si-do.” “When they dance, we vanish.” Molly tapped her comms to count down, and the hallway scent of frosting drifted outward. Bill slid the lock plate with his magnet tool. A muffled cheer rose; someone opened a bag of confetti. Molly reached for the biggest box, then paused as a tiny sticker squeaked, calling her name. It read, 'Happy birthday, Molly!' in glitter.
