The Maine Massacre And Two Other Great Mysteries

Description for THE MAINE MASSACRE AND TWO OTHER GREAT MYSTERIES by Janwillem van de Wetering:

The accidental death of his brother-in-law sends the commissaris to the icy, secluded town of Jameson, Maine. As part of an international police exchange, de Gier goes along to see the USA. But when it appears the death of the commissaris's relative was the sixth in a series of mysterious deaths in the area, he and de Gier find themselves neck-deep in murder, American style--with shady real estate deals, a list of suspects including nearly everyone in town, and the icy breath of a cold-blooded killer stalking their every move.

This is #7 in Grijpstra & deGier Mystery.
