19/series. The real treasure in a series this long and complex is getting to know the flow of the lives of the characters, whether major or minor. Getting to know Venice better is a plus. Commissario Guido Brunetti investigates the life of a deaf mute who has died of what appears to be an overdose. As he slowly peels away the layers surrounding the past of this often overlooked man, he discovers increasingly distressing details. More subtle than the usual tales in this series, but as always a fine read with interesting characters. It's a 3.5; not one I've liked best, but a must-read if you enjoy Brunetti and his world.
