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 the book description of
Have No Mercy, “The best of us have had an occasional thought on how to even the score with
an enemy. Typically, conventional wisdom overrules such erroneous thinking. Then, an individual forgives or at least moves
forward, forgetting the past. Not the case with David Epstein.”
Joan Moore Lewis (author of Southern Fiction) said of Have
No Mercy, “Greed, deceit and murder are the three main ingredients in "Have No Mercy." There
is more than one crime committed, however. Crimes without bodies, crimes against spouses, crimes within the law for which
there are no penalties. Although it's not obvious in the beginning, all major characters seem to have an ulterior motive
for most of their actions.
Ann thinks she has landed the perfect husband, one whose money and social position
is exactly what she has always expected. David thinks he has the perfect wife, one who is brilliant, beautiful and loyal.
Both are disappointed. Todd needs money; Rennie needs a home and children. Theirs could be the ideal marriage,
but their money and house do not make a home. They are childless, and not a single other need is fulfilled.
The way the four lives are intermingled is complicated. I could not finish the
book in one night, but neither could I put it down. It's one of those "turn on the light at 3AM" books. The
suspense is deafening. Bobby Ruble, author of "Have No Mercy," retired from the Marines where
he served ten years in the Criminal Investigation Division, and he is an FBI National Academy graduate. His achievements are
too many to list, but it is obvious that he has the credentials to write this book.
I usually try to guess what is going
to happen in a suspense novel. For those of you who think you can figure out what's going to happen before the end, you
will be in for a surprise. Bobby Ruble has no mercy.”
