Island of Bones by Imogen Robertson
This is the third in the series about Harriet Westerman and Gabriel Crowther, set in the 18th Century. Harriet is a women of independent means and independent spirit. She is beginning to make a name for herself as an investigator of sorts. Gabriel is a pathologist at a time when pathology was in its infancy. The pairing make for an interesting and intelligent read.
Harriet is recently widowed (in the previous book, which I haven't read) and she is seeking distraction from her grief. When she is invited to travel to Cumbria to the former family home of Gabriel to investigate a mysterious body, she leaps at the chance. Gabriel is less keen to rediscover his family history which is a grim one.
I really liked this, thought it was clever and atmospheric, with interesting characters. I'd read the first in the series which is called Anatomy of Murder and liked it. I do have the second one somewhere but half of my books are in boxes so I'm just reading what comes to hand.
Anyway I enjoyed this and will certainly read the others.
