According to the book description, “Excessive Forces, A Pittsburgh Police Thriller by real-life police detective Dennis Marsili who draws his characters from his own world and life experiences, taking readers into realities normally hidden from public view. Pittsburgh police officer Guy Ruggerio is a proud, competitive, overachiever who loves his job, his police buddies, and his city of steel. But all of that collapses into despair on the night he is involved in a line-of-duty shooting and set-up for destruction. Detective Joe Massimo is fiercely protective of the younger Ruggerio and he is determined to clear his friend s name. But powerful forces are against Ruggerio even as Massimo brings together a group of like-minded fellow officers to right the injustice. Their efforts take them into the seedy world of contemporary crime as it is played out on the twisted back streets and stunning vistas of Pittsburgh s three rivers. This cop story is an action-filled pressure cooker with a poignancy rarely experienced in the genre.”

One reader of Excessive Forces, A Pittsburgh Police Thriller said, “This book does give a real inside look at life as a police officer. I am not a cop myself, but I have a high degree of respect for those who are. Although this book is fiction, it does educate the reader on police procedure and the politics cops sometime have to endure. Most importantly, it is a very interesting story. I think the characters were developed effectively and the story line was suspenseful. There are plenty of surprises along the way. Even though I mostly read true crime stories and biographies, I really did enjoy this book. I understand the author is a retired police officer and this is his first book. I hope he writes more in his retirement. I will be sure to read them.”
