Edward Albright is an agent with an ultra-secret American Intelligence organization.
Henry Spivey is not. He is an efficiency expert who lives a solid, totally unexciting life far from danger and excitement. He is happy doing just that, pleased to be married to his lovely and loved wife Angie who also is happy to married to him. They are both pleased to be the parents of Ruthy and Jack, their two young children.
The interesting fact behind those two statements is that Albright and Spivey are the same man. Albright knows about Spivey but Spivey has no idea that Albright exists. Spivey is not aware that Albright speaks over a dozen languages flawlessly, or that Albright can and has taken lives in the service of his agency, or that Albright is not only physically able to handle himself in a fight, he would likely enjoy the opportunity. Albright loves adventure and danger. Spivey does not.
So the drama that makes up the majority of the few recorded adventures starts when Spivey, who is not supposed to ever know about Albright, starts to see the truth. He is kept from knowing his alter-ego by means of a chip implanted in his brain which Albright's handlers have control of. When the super-spy skills of Albright are needed, a signal goes out and the chip does its flip and Albright takes over. When the mission is complete, the switch is again flipped and Spivey is back. It is a great system - until the chip malfunctions and Spivey starts to learn about Albright.
Why the chip exists and why Albright/Spivey has this strange duo personality are never, as far as I found out, explained very well. Why the subterfuge and the deception. When did Spivey meet his wife and get married and have children and where was Albright during all this? Those are some very valid questions which unfortunately never got a chance to be answered.
