Jeri Westerson (born 1960) is an American novelist of medieval mysteries, historical novels, and paranormal novels, along with LGBT mysteries under the pen name Haley Walsh.
Westerson, born and raised in Los Angeles, California, originally had designs on a career as an actress but changed her major in college to graphic design. After graduating, she continued as a successful commercial artist in the Los Angeles area for fifteen years before semi-retiring to start a family. She began writing seriously for publication two years after that. She became a newspaper reporter for the next eight years, writing as a stringer for several local papers to hone her skills. After that, she had several part-time jobs while continuing to write historical novels, including tasting host and tour guide for a local winery, choir director and soloist for a church, theology teacher, and secretary. She sold her first medieval mystery novel, Veil of Lies, in 2007 to St. Martin’s Minotaur. Her series is styled a “Medieval Noir” with a hardboiled protagonist set in the Middle Ages. Her debut medieval mystery with protagonists Crispin Guest, a disgraced knight turned detective, along with his cutpurse servant Jack Tucker, received a nomination for the Macavity Award (Sue Feder Historical Mystery Award) and the Shamus Award for Best First Mystery, the first medieval mystery to be nominated for this PI award given by the Private Eye Writers of America.
The second Crispin Guest novel, Serpent In The Thorns, was released in 2009, and received nominations for the Bruce Alexander Historical Mystery Award and the Macavity Award (Sue Feder Historical Mystery Award). The third Crispin Guest novel, The Demon’s Parchment, was released in 2010 and also finaled for the Macavity Award and the Romantic Times Reviewers’ Choice Award. In October 2011, Minotaur Books published her fourth medieval mystery entitled Troubled Bones. It received nominations for the Macavity, RT Reviewer's Choice, the Bruce Alexander Award, and the Agatha. In October 2012, her fifth, Blood Lance was released and was named one of the “Ten Hot Crime Novels for Colder Days” by Kirkus Reviews. Her sixth and last from Minotaur Shadow of the Alchemist, was released October 15, 2013. It was nominated for the RT Reviewers' Choice Award and was named by Suspense Magazine as one of the Best of 2013. Jeri decided to release a prequel to the series, Cup of Blood, on her own under the label Old London Press. The book was released July 25, 2014, and was nominated for the Bruce Alexander Award and semi-finaled for the M.M. Bennetts Award for Historical Fiction. Severn House, a UK based publisher, picked up the series beginning with The Silence of Stones—released first in the UK in November 2015 and in the US in February 2016. Her follow-up A Maiden Weeping released in the UK in April 2016 with a US release in August 2016. Next came Season of Blood, which also garnered a nomination for the Bruce Alexander Award  with the next book, The Deepest Grave released in the US in August 2018. The twelfth Crispin Guest book, Traitor's Codex, will release in 2019. All told, the series has garnered thirteen national mystery nominations so far.
Jeri ventured into the world of the paranormal with a paranormal romance entry, Booke of the Hidden, released October 31, 2017 by Diversion Books. The second in the series, Deadly Rising released in October 2018.
In 2010, writing as Haley Walsh, Jeri published the first in a series of LGBT romantic comedy mysteries with high school English teacher and amateur sleuth Skyler Foxe, with the book Foxe Tail, published by MLR Press. The second in the series, Foxe Hunt, was released in September 2011, and the third, Out-Foxed was released November 2012. A follow-up novella, Foxe Den was self-published in December 2012. The next full-length Skyler Foxe mystery, Foxe Fire, was released in January 2014, and the fifth, Desert Foxe was released November 2014. Two novellas, Foxe Den 2: Summer Vacation and A Very Merry Foxemas were published in 2015. Crazy Like A Foxe, the next full-length mystery, was published in 2016, and the last of the series Stone Cold Foxe was released in 2017.
In 2011, author Tim Hallinan asked Jeri to participate in a short story e-book anthology whose entire proceeds would raise money for Japan earthquake relief. The book, called Shaken: Stories for Japan, includes nineteen other authors, such as Brett Battles and Ken Kuhlken. Jeri offered her historical short story “The Noodle Girl” for inclusion in this Japanese-themed book.
In 2012, she was asked by two other editors to contribute to anthologies, the November released Murder and Mayhem in Muskego and 2015's serial anthology, Day of the Destroyers. Her gay erotic short story under the name Haley Walsh, "Marked," was included in the anthology Anything for a Dollar, edited by Todd Gregory, released October 15, 2013.
Jeri used to write on a series of blogs. Her own was what she called a magazine of history and mystery called Getting-Medieval, but she has since shut it down. She also wrote on a group blog with five other mystery authors, called Poe’s Deadly Daughters, but it has, since January 2014, closed its doors. Her medieval detective, Crispin Guest, also has his own blog on Jeri's website.
Jeri served two terms as president of the Southern California chapter of Mystery Writers of America from Jan 2013 to Dec 2014, is former Vice President of the Sisters in Crime Los Angeles chapter (Jan 2012 to Dec 2013), and has served two terms as past president of the Orange County California chapter of Sisters in Crime.
