Wash This Blood Clean from My Hand by Fred Vargas

4.0

Vargas comes through again with a winner. Adamsberg reappears in this one, dealing with a spectre from his past, the Trident. A chance glimpse brings this figure back to his life and gets him on the track that he abandoned years ago. Others are sceptical of his theories. His group at work makes a trek to Quebec and the spectre appears to be tracking him there as well. Does Adamsberg obsession lead him to commit a similar crime. Who is on his side? There are lots of twists and turns and interesting characters.
