Very interesting crime thriller released in 1970, just one year after the Stonewall gay rights riot. Damaged and guilt ridden Mitch Tobin, disgraced ex cop, is reluctantly drawn in to investigate the murder of a gay successful men's boutique store owner by the victim's partner in life and business. The homophobic cop assigned to investigate has written the murder off as a pick-up gone bad. Mitch Tobin is quite astounded the victim's partner faultless methodical approach to find who the possible murderer could be, narrowing it down to seven suspects without firm alibis. But then he is stumped to go any further and turns to astrology for inspiration, but fails, thus bringing in Mitch Tobin to help. Although not a licensed PU, Mitch investigates the seven homosexuals who could possibly have committed the crime. It's the only novel I know to give detailed birth facts for all characters: place, time, date of birth. Although several of the characters are very interested in astrology, the author states he is neutral on the topic. For a novel of 1970, it's quite sympathetic to all the characters, causing Mitch to examine his own attitudes, to look for who the killer is, while being disgusted by the lack of concern and effort of the cop on the case, who is riddled with disgust for the victim and all his gay friends. Mitch's work on the case and his interaction with the homosexuals, changes his attitudes and his life. Although we may now disagree with some of the depictions of the homosexual characters, think less of our views now, and more of the original Boys in the Band. Westlake gives us his usual very fine writing, observation and style. It's also very touching and poignant. Read the previous three novels in the series first if possible.
