The Case of the Whistling Wanderer. Jitter Jumpers, #28

Idris likes his world quiet, tidy, and predictable. Sounds have sources. Questions have answers. So when a broken, off-key whistling begins drifting through his house, coming from nowhere and everywhere at once, Idris knows something is wrong. The sound doesn't follow rules. It doesn't leave clues. And no one else seems to hear it the way he does. As the melody returns again and again, pulling him deeper into forgotten spaces and buried secrets, Idris must confront the one thing he fears most: the possibility that some mysteries don't want to be solved.
