Steven F. Havill Biography

Steven F Havill

Steven F. Havill is an American author whose work includes the Bill Gastner mystery series, the Posadas County mystery series, the Dr. Thomas Parks historical series, and several standalone western novels. He has written more than 30 books since his debut western, The Killer, in 1981.

Steven F. Havill was born on June 22, 1945, in Penn Yan, New York, the son of Edward Havill, also a writer. He married Kathleen Murphey in 1969, and earned both his B.A. in 1969 and M.A. in 1982 from the University of New Mexico. He worked as a reporter and editor before becoming a high school biology and English teacher in Grants, New Mexico. He later earned an AAS degree in gunsmithing, which is a detail that inspires the precision of his procedural writing.

The first Steven F. Havill book, Heartshot, which is also the first in the Bill Gastner series, was published in 1991. The story is set in Ruidoso, New Mexico, in southwestern New Mexico. Posados country is an imaginary border country. Already in the first book, Bill Gastner was already fast approaching retirement, as he was 60 at the time. That’s why the original series is relatively short, with only nine main books, which is then followed by the Posadas Country series that continues today.

Easy Errors, published in 2017, is a prequel of the series that takes us back to 1986 when Bill Gastner was an undersheriff. The story focuses mostly on Deputy Robert Torrez’s first big case from back then. It should be read after One Perfect Shot. Next, the author shifted the series focus to Estelle Reyes-Guzman with Scavengers, published in 2002, keeping Gastner as a recurring supporting character.

Steven F. Havill lives in Datil, New Mexico, with his wife Kathleen, a writer and artist.

  1. I’m rereading Steven Havill’s books and thoroughly enjoying them again — in order this time. I’m going to ferret out the old Westerns. His Dr Parks stories are a wealth of real logging and medical dangers. The language could be much more polite way back then but the dangers! Oh, the dangers. Every bit as twisted and dastardly and sudden as anything a criminal mind can offer up today.

  2. I really enjoy the series and I listen to them all as audiobook versions.

  3. I am just making sure I am not missing something – there is a large multi year gap between when Come Dark and lies Come Easy take places that correct?
