After years as a writer, newspaper editor and communications director, Tierney began writing mysteries in the late 1980s.
The Stone Veil introduces semi-retired, Indianapolis-based private investigator Deets Shanahan.
It was also nominated for the Private Eye Writers of America's Shamus Award for "Best First Novel."
After Moving to San Francisco, Tierney embarked on a second series involving the strong and passionate Carly Paladino, the lead investigator for a large, prestigious San Francisco security firm and the down on his luck, streetwise P.I.
Tierney's novels have been published by the UK's Severn House, St. Martin's Press and Dutton (Penguin Group).
