In Broken Harbor we again meet members of the Dublin Murder Squad and like French’s previous three novels, this is a very complex psychological mystery. It starts out with the murder of a family and the two detectives that are sent to unravel the mystery. As they search for the answer to this terrible crime, they are forced to delve into the dynamics of a family on the brink of financial ruin and the mental fatigue both parents felt from this stress. There is eventual resolution, but in the process of solving this crime, both detectives lose perspective — to the point of making costly decisions that lead to unhappy consequences. This is a very engrossing novel, but not a light read by any means.
