A historical thriller about a young woman's affair with the Prime Minister.

The young woman is 26-year-old socialite Venetia Stanley and the Prime Minister is H. H. Asquith.

As Asquith reluctantly leads the country into war with Germany, a young intelligence officer with Scotland Yard is assigned to investigate a leak of top-secret documents.

Harris weaves romance, espionage and political intrigue into this novel; as a master of the historical fiction genre, he creates a narrative that brings to life a little-known historical event using the actual letters and telegrams that Asquith and Venetia used to correspond with each other.
