One of the top-rated games on textadventures.co.uk, Victorian Detective has you take on the persona of a distinctly Sherlockian police detective to solve a murder.
The structure of the game is, intentionally or not, very similar to the Conan Doyle stories, in that the titular detective makes an impressive but slightly far-fetched inference about some tiny observation, which determines the entire course of the investigation. Victorian Detective rewards detailed reading by carefully firing Chekhov's guns, even if the clues given are sometimes frankly esoteric (Spoiler - click to show)(I don't know, but can you identify the smell of haddock compared to other fish? This isn't Toby's Nose!).
Although this game predates Toby's Nose, the way both games get the reader to come to their own conclusions is quite similar, and indeed constructing a web of clues for the reader to pick apart is no mean feat.
This game is relatively well thought out. Occasional illustrations add a whimsical tone to the story, and in at least one point serves as a plot point. Not the most solid mystery, but mildly entertaining.
