His novels include Daydreams (1987), which centers on a female detective investigating the murder of a call girl; Stone City (1990), a mystery set entirely in a maximum security prison, where an imprisoned professor is appointed by the inmates to solve a series of murders (remarkably similar to the HBO series Oz (1997) in its initial premise); Due North (1992), concerning a woman who returns to Seattle from the Alaskan wilderness to care for her dying mother; Karma (1994), a thriller featuring Hindu mobsters; Sacrifice (1997), a thriller in the vein of Floridian crime writers (Charles Willeford, John D. MacDonald and Carl Hiaasen); and Reprisal (1999), a tale of familial revenge and psychological horror which is celebrated in an essay by Michael Shea in Horror: Another 100 Best Books.
