Jeri Westerson is an American historical mystery novelist, born and raised in Los Angeles, whose fiction reflects a longstanding fascination with medieval English history. Before becoming a full-time novelist she worked in a variety of occupations and later became active in organisations including Mystery Writers of America, Sisters in Crime and the Historical Novel Society. Her work is particularly associated with what she calls “Medieval Noir”: crime fiction that applies the atmosphere and moral ambiguity of noir to carefully researched medieval settings. Her novels have received numerous nominations for major mystery awards, including the Agatha, Macavity, Lefty and Shamus awards.
Westerson is best known for the fifteen-book Crispin Guest Medieval Noir series, beginning with Veil of Lies. Set in the reign of Richard II, it follows Crispin Guest, a disgraced former knight who earns a living as a private investigator on the streets of fourteenth-century London. She later created the King’s Fool Mysteries, featuring the real Tudor court jester Will Somers as an investigator during the reign of Henry VIII, beginning with Courting Dragons. Her historical fiction also includes standalone novels such as Roses in the Tempest and Oswald the Thief, while the Irregular Detective Mysteries move forward to Victorian London and follow former Baker Street Irregular Tim Badger. Across these books Westerson combines murder investigation with social history, politics and real historical figures, making the detective story a way of exploring how people navigated the rigid hierarchies and dangers of earlier societies.
