Tehran Revisited is the fictional memoir of author John Sager, who served as part of the CIA's Tehran station in the 1950s. He sometimes dreams of returning for a brief visit, knowing it's unrealistic. Instead, this is his story.

The tale is contemporary, as the American president—frustrated by his unavailing tweets—has directed the Central Intelligence Agency to bring about regime change in Iran. The critical caveat is to have no American fingerprints.

Using a most unlikely array of agents and helpers, the agency succeeds in its mission, but not without the help of Roya, a beautiful young woman who has the last word.
