Kathy Reichs books are similar hc .But she went off the boil too .
The character is a forensic anthropologist . It spawned the TV series Bones .
But you may like her first ones .I got as far as Flash and Bones then gave up .
It must be difficult for these authors to keep such successful characters going .
I couldn't write for toffee and admire people that can ,but you can flog a horse to death and sometimes I think they should just kill them off and end it while the going is good .
Ohter series which are good and consistently good are
Donna Leon ..Inspector Brunetti
Peter Robinson ..Inspector Banks
Peter James ...DS Roy Grace
James Lee Burke ..Robicheaux ..set in New Orleans
Christopher Fowler ..Bryant and May .
You can look them up here
