There were two books written by 'David Hunt', a pseudonym used by William Bayer who also wrote the Janek series. The central figure in the Hunt books was Kay Farrow, a street photographer who had a congenital vision problem that left here unable to perceive colors, and with so much sensitivity to sunlight that she did most of her shooting after dark. Both stories took place in San Francisco, and provide a very comfortable read for those who are familiar with the Bay Area.
The first book, "The Magacian's Tale" was about the murder of a male hooker who was Farrow's friend and sometimes photography subject. The twist was that the murder was patterned after a series of murders that occurred many years earlier that resulted in Farrow's father having to resign from the police department and eventually to her mother's suicide. Photography was more than just the profession of the central figure, and had a major role in the story line.
The title of the second book was "Trick of Light" and was about the murder of Farrow's photography coach. The trick in this story was an exclusive hunting club that catered to socialites and that provided both sexual and extreme (ie, human) hunting experiences. Again, photography was a key element of the story.
Both books were written in the late 1990s, and there has been an unfulfilled promise on the author's web site of additional books in the series, but nothing substantive has been forthcoming.
