Trick of the Dark

This thriller Trick of the Dark by Val McDermid was a little disappointing as I normally enjoy her work. Psychiatrist Charlotte (Charlie) Flint is asked to investigate a series of murders by one person. We are kept guessing until nearly the end before we discover the truth about the murders - and that's good. All the main characters are lesbians, but I question whether that was necessary to progress the story or did the author merely want a stage for them. If one or two were lesbians that wouldn't be an issue for me, but for all of the main characters to be gay was overdone. Parts of the story seem contrived to further this aspect and that made the story less credible than it might have been. (I was interested to read an Amazon review by a lesbian who agreed). 31/2/5
