One of my favorite genres that I do not actively pursue as such is Mysteries. But if you break it down, MANY different genres either incorporate, or flat out evolve into mysteries as the story unfolds, from Action/Adventure and Thrillers, to Ghost Stories and a number of Slasher films (of the non-franchise variety, where the killer's identity isn't known), for example.
And who doesn't love Sherlock Holmes, Phillip Marlowe, Columbo, Matlock, etc. :)
In a way, solo rpg'ing feels like a mystery when I'm playing. You're proceeding into the unknown, looking for clues, interviewing suspects and witnesses (NPC interactions) and following a trail.
One of the subjects that has interested me is how to conduct ACTUAL Mysteries in SOLO RPG's. How to uncover REAL clues, at least "simulate" doing deduction, and have them add up to a Solution.
It's not a subject I've given a LOT of thought, but have considered in passing. Especially, as said previously, many different genres incorporate mystery elements (the "monster-of-the-week" horror game I ran is another great example).
In any case, here is a link to another blog post on that very subject that has some fascinating ideas that I will definitely be trying in the future.

Pay special attention to the comments. The one by Ulfengaard Hrafnson is pure gold.
And as a bonus, here is a series of blog posts that, even though they didn't have the approach to mysteries I was looking for, were an entertaining read and a GREAT example of the Mythic GME in action:
