Ian K. Smith

Ian K. Smith combines work as a physician and broadcaster with practical health writing and Chicago crime novels. The Unspoken begins his Ashe Cayne mystery series. Cayne, once a city police officer, has resigned rather than accommodate corruption and now investigates cases privately. A prosperous family's missing daughter draws him through neighborhoods and institutions shaped by unequal access to wealth and authority. Thomas & Mercer introduced the series in 2020. Smith later returned to Cayne in Wolf Point, The Overnights, and Eagle Rock, extending a sequence anchored in Chicago streets, politics, and civic tension. Readers may also know Smith through wellness titles including Shred and The Clean 20, but this series gives him a different vehicle for examining systems and individual judgment. Cayne's independence, careful local knowledge, and guarded history guide each inquiry, especially when official channels cannot or will not pursue the answers sought by the people who hire him.
