Mystery and detective horror games in your browser

12 mystery and detective horror games in your browser, each with a page on what frightens and a link to where it is sold. Investigating a mystery is a main way to play: gathering clues or evidence, questioning people, deducing what happened or who did it, as in Call of Cthulhu, The Sinking City or Phasmophobia's evidence hunting. A horror game with a mysterious story that the player only follows, without investigating, does not count.
