"A Diamond worth Killing For", is a thriller. The action takes places in Northern Quebec, in winter: then spans to Montreal, London, New York, Chicago and Toronto. In April of 1938, Schakowsky, a geologist, accidentally finds a large diamond when investigating a strong magnetic anomaly north of Chibougameau. In order to steal the diamond and to keep the discovery secret, Schakowsky is murdered. His body was never found: he was given for lost. Killed by wild animals, or drowned.
Thirty years later, Frank Gauthier, an engineer fresh out of school, leads a second exploration in the area. Frank is intrigued by the field notes written by Schakowsky in 1938. Frank's curiosity, and his nosing around, convinces the murderer, now a rich man, that Frank will discover what really happened back then: he has to be stopped. Frank barely escapes death, but his assistant is murdered. Frank is falsely accused of killing him. Frank is able to flee the area, during a late winter storm, with the help of the local Indian tribe. This is where he meets his future lover, Hopi, the daughter of Chickasha, the Chief of the Cree Indians. Pursued by the police and by hired killers, Frank conducts his own investigation to clear his name and to find what really happened.
As the investigation progresses, Frank's newly acquired knowledge of what really happened back in 1938, is confirmed through frequent flash backs. They explain how the rough stone was cut by a diamond cutter who flew Antwerp during World War II to escape death, and how the stone was illegally sold, in 1946, through the "Correspondence Office for the Diamond Industry", an organization set up by the Jewish diamond traders, to return diamonds to their rightful owners.The police is eventually convinced of Frank's innocence, stops actively chasing him, and starts its own parallel investigation.Frank's investigation in London, through a surrogate, leads him to short lists four of the 345 plus diamonds sold there, through an auction organized by the Office, in the spring of 1946.
Following this lead, Frank's moves to New York and Chicago. Searches through immigration files and police records, lead to the short listings of six possible diamond cutters; and of the woman who has fenced the sale of the diamond. These are all potential witnesses. One of them is murdered, but the second one is finally brought into custody and identifies the killers.
The environment where the action takes place is described in detail: the reader experiences life in the harsh winter conditions of Northern Quebec, and the easy life of Montreal in the spring. These are all places the writer has lived or worked in: the reader feels he has been there as well.
