This is a steady and entertaining crime mystery story.
Set around Exeter in the time just after their floods a couple of years ago, the police try to solve a particularly gruesome murder with the help of the book's heroine, the lead detective's ex-wife, Lizzie. There is enough going on otherwise to make this more than a standard murder mystery, centring around relationships between the police officers, and the surrounding cast. Also, and of most interest, is the climate change link. The murder was in the house of a scientist renowned for his views on climate change, and he is the chief suspect.
My chief criticism is that the sexual antics are really not for me, and detract from a story that would have been stronger if it was shorter.
