Timothy Hallinan is an author of three mystery/thriller series: Simeon Grist (written in the 1990s), Poke Rafferty (written in the past 6-8 years) and Junior Bender (written in the past 3-4 years). All are VERY enjoyable books (IMO), and right now (not sure how long it lasts) the first Simeon Grist book "The Four Last Things" is free on Amazon US at:
