Thank you for checking out my mystery/thriller novels. True-crime research provides plenty of inspiration for my fiction stories.


Unknown Revenge 2021

(School Marshal Novels Book 4)

“Beware the fury of a patient man.” -John Dryden

A Mystery/Thriller novel.

There’s a killer in Brookfield, California.

Law enforcement and the community of Brookfield soon learn there’s a hunter hiding in the forest, but they don’t know who he’s hunting or why.

Join USAF Veteran Mac MacKenna and his good friend, ex-FBI agent Nico Stark, as they assist the Brookfield Police Department to solve the heartless murders they didn’t see coming.

They need to find a connection between the victims—not knowing if there’s another target, time is of the essence. But with no leads, no evidence, and no witnesses, they have to depend on old-fashioned police work.

Before the investigation produces a viable lead, Mac’s personal life spins out of control. His sister, Maggie, is missing. Is he the connection to the killings? Will Maggie be the next death? Mac will do whatever it takes to find her…alive.
