Robert Ruble quit high school to join the United States
Marine Corps (USMC), where he was hoping for Korea, but instead was selected to be a Drill Instructor at Marine Corps Recruit
Depot (MCRD), San Diego. Later he changed his specialty to Tank Crewman. He left the Marine Corps and joined
the Tampa Police Department. After a few years as a police officer he re-enlisted in the Marine Corps and
served a 20 year career, including two tours in Vietnam.
After retirement from the USMC, he worked for a variety
of law enforcement agencies culminating his law enforcement career as the Chief of Police of the Kennesaw Police Department
(Georgia). He was their chief from 1980 through 1986. He has written two thrillers -
Have No Mercy and Black Rosebud: Have No Mercy II.
According to one reader of Black
Rosebud: Have No Mercy II, “is a powerful crime tale that provides readers with a slice of rural Midwest.
Though exciting, the shrewdly designed investigation plays a support role to the relationships between residents of the county;
the audience will feel like a Cornhusker tasting the dust of Nebraska's farming community. Readers will welcome this suspenseful
story that uses individual and community de facto prejudice to add depth to the tale. Those who prefer a sleek crime thriller
will probably be better suited elsewhere; anyone who takes delight in a minuscule look at people in a community where crimes
have happened will appreciate this book and seek its predecessor, Have no Mercy.
