I'm not sure if you mean that you like mystery / detective / thrillers, but not the 'unreliable narrator' sub-genre, or if you want recommendations in general.
I do love mystery & detective stories, but dislike unreliable narrators, as they break the rule of having all the clues in front of you (although I will make an exception for The Murder of Roger Ackroyd, which does in fact have all the clues!)
If I step outside that genre, I do like JoJo Moyes, but am going to make most of my recommendations from the genre I enjoy.
I second Lindsay Davies' Falco books, and the new ones about his adopted daughter Flavia Alba.
Elly Griffiths has written some great modern detective stories, and one series set in 50s Brighton.
I also love the Bruno, Chief of Police series, set in the Dordogne, written by Martin Walker.
Kate Ellis mixes modern detection with historical parallels.
I recently heard Madam Will You Talk as a radio adaptation - it was very enjoyable.
