Five volumes in the series so far. Volume six is planned for January of 2026.
The series features a former Secret Service agent who is much like the heroes of the pulp fiction stories of the past. When Duane was a teenager, he read the works of Edgar Rice Burroughs and the Doc Savage stories. As well, he was a fan of James Bond. At this stage in life, he enjoys Clive Cussler books. So…. he decided to create a character who is a mix of Trazan, Doc Savage, James Bond, and Dirk Pitt — yet this man is believable, has no super powers, and everything he does could actually be done. He is big and strong, yet smart and clever. The stories have fascinating characters — including a strong female character who is Thomas’s secretary and love interest — with adventures of an international scope.
