The Janus Deception — John F. Bayer

Lieutenant Commander Jake Madsen, MD, USNR, feels he has very little left to live for since his wife, Kathy's death. During Madsen's two weeks' active duty at Naval Support Activity, he examines Sgt. Jerry Wallace, one of three survivors of a chemical attack in the Saudi Arabian desert. Madsen discovers a strange implant in Wallace's chest. The discovery of the implant propels Madsen into a world controlled by a computer program, where human emotions and actions are no longer taken into account, where humans have abdicated responsibility -- and accountability -- and where research on chemical weapons is conducted on the most available and expendable subjects: soldiers of the United States. Jerry Wallace is a human guinea pig.

When Wallace is murdered, Madsen and Naval Criminal Investigative Service agent, Kaci Callahan, combine forces to battle the horror of chemical warfare testing on U.S. military troops in an impersonal world controlled by computers. In the process, each comes to a better understanding of themselves.
