In this newly published third entry in the Karin Muller series, from an upcoming total of five books, the mid-1970's East German police are focused on the suspicious deaths of several homosexual young men. The capable author does take some artistic license for this mystery, but it is largely based on the true misuse of young gay men under the East German Stasi, not to mention US companies' research trials allowed to run in cash-strapped East Germany, so the Iron Curtain country could earn more Western money. Karin Muller continues as the buffeted lead character, but the book can stand alone without having to be read third in line. This paperback was purchased online from Amazon, United Kingdom. It is good to read that the author has gotten a contract for 2 more books, as he writes knowledgeably about East Germany in the recent past, thus effectively increasing the reader's tension as the murder mystery thickens. Stayed awake all night reading this; already anticipating the next in the series. Not pornographic, this well-written thriller is recommended for high schoolers and adults.
