During my thirty-two years with the state department of public safety, I worked with law enforcement and fire officials at the state, county and municipal levels. Those interactions assisted me with writing mysteries, but were just the starting point. Without the help of a friend who spent thirty-five years as a cop, I would never have ventured into writing police procedurals. He contributed to my understanding of the perspectives of my two protagonists, Pete Culnane and Martin Tierney Thankfully, this friend is still a resource. He proof reads each manuscript and performs a reality check on the law enforcement aspects.
