Murder in the House of Diamonds by Charles Kane
This is not a work of fiction. It is the story of a man who goes searching for his past in an attempt to solve a murder. It begins shortly after his birth in Brussels during the Nazi occupation. Thirty-five years later, Charles Kane would learn that his birth mother had been killed at Auschwitz. He would come to this discovery after the murder of his adoptive mother, a diamond dealer—and one of several Jewish jewelers who met violent fates in beautiful San Juan during the dark decade of the 1970s.
