According to the bio on Amazon: "I retired in late 2015. Three days later, my wife and I were headed to Panamá City, Panamá where we intended to live as American ex-pats for the duration..... We'd visited Panamá a couple of times, driving across the country and back. We looked forward to a more active, healthier and less expensive lifestyle. That isn't the way things evolved and we returned to the States, as many American would-be ex-pats do, 13 months later.
While living in Panamá, an idea for a book series began forming in my head. I imagined an American, a former CIA officer, retiring while he was fairly young and very healthy, retiring to Panamá. The Max Springer series was born."
