I can see how mystery techniques have been used in your story, and especially how it’s possible to both distract and draw attention (so pieces can come together). It sounds like you’ve got a lot of practice in your own work. It might be interesting to reach past what you are doing to a specific work by someone else. There may be some surprises. Also, you might explore adapting what you learn, moving past clues to solve a mystery to using similar techniques to support the character arc without being obtrusive.
