Michael Devon runs a security service.
This high-priced, and highly respected business specializes in keeping alive those who travel overseas to regions known for not being the safest. His minimum price per assignment is one million dollars and often charges more when the case deserves it, which it often does. On top of that come expenses and since Devon demands the ultimate from himself and his colleagues, he insists on providing the very best in equipment and logistics.
After service with the military, he worked for several years for the CIA eventually rising to the position of Director of Operations. After a time when he was considering leaving, the issue was settled for him with a Congressional witchhunt decided the Agency was a vulnerable target and Devon, having just orchestrated the overthrow of a dictator in Central America, was a very visible bullseye. He was forced out.
Still fairly young in his opinion, well respected and with a considerable number of friends and influential associates, Devon didn't fade away. He created his own company and gathered many very skilled operatives met during his previous life, not just from the CIA but from other agencies. Devon demanded the best. With them to help, his considerable reputation just grew stronger because he got results.
With the high fees he charges and the success rate he has amassed, Devon has become a wealthy man, able to own a large estate on Captiva Island in Florida. It is from this palatial manor, strongly reinforced for security, that Devon runs his business when he is not out on assignment himself. Devon might not have to go but sitting at home would drive him crazy. And though he is no longer a young man, he is still one of the best he knows.
