The June 20, 2013, issue of New York Review of Books had (what I thought) was an interesting review of Derek Raymond's work by Joyce Carol Oates. For those who might be interested: The Visionary Detective
I have a couple of favorites. One is John Sandford's Lucas Davenport series: all titles have "prey" in them. He has another series that I don't read, can't identify with the protagonist. I also like Lisa Gardner's Detective D.D. Warren series. DD works homicide for Boston PD, so most of them are set in the Boston area.
