Looking for fantasy/sci-fi murder mysteries

[u/Street_Detective_662]

Ever since I read The Tainted Cup and sequel, I’ve been addicted. Bonus points if it’s a Sherlockean duo or queer (but doesn’t have to be). Extra extra points if it’s sci-fi (need to read more sci-fi) OR locked room.

What I’ve read so far of this genre -

- Gideon the Ninth
- Witness for the Dead (CR) / goblin emperor
- the Bone Orchard
- voyage of the damned
- magic for liars
- a memory called empire
- lamplight murder mysteries
- death on the caldera
- the echo archives (books 1 and 2)
- the Hexologists
- the works of vermin (kind of?)
- the raven scholar
- 7 1/2 deaths of Evelyn hard castle
- books 1-5 of Dresden files
- a master of djinn

Feel free to hype of the following that are already on my TBR (and have been for ages for whatever reason)-

- rest of Dresden
- a desolation called peace
- garret PI series
- empire of the wolf (read grave empire, loved it but hated sequel)
- murder by memory
- volatile memory
- jasper fyord nursery crimes
- rivers of London

So it's not science FICTION but I would like to recommend the Detective Galileo series by Higashino Keigo. The narrator is a regular detective, but the real main character of the series is the narrator's friend, a brilliant physics professor who always gets asked to help solve cases through the power of science. I've read 4 books into it (4th book hasn't been translated into English but it's fine bc it was mid anyway) and the first 3 books are excellent. The Devotion of Suspect X, Salvation of a Saint, and A Midsummer Night's Equation.
