A Dying Fall by Elly Griffiths
Published 2013, Houghton Mifflin Harcourt
This was probably my favorite one since the first one. Plenty of suspects, a different locale that set our team on edge, actual danger for some of the characters, and...
I thought I had the killer(s?) figured out, but I was pleasantly surprised to find that I was wrong.
Highly entertaining one, this. :)
