The book that started it all. Jack Blackwood is a lonely drunk who starts a detective agency in the heart of Washington DC. As Fort Sumter is attacked, he and his partner Ezra are embroiled in a case that could change the very course of the war: the son of a retired congressman has gone missing, along with military papers outlining the Union's Anaconda Plan. At the heart of the matter is a beautiful prostitute, a trail of dead men, and a spy who will stop at nothing to deliver the plans to the Confederacy. The investigation uncovers murder, blackmail, and the plight of a woman scorned. Will Jack survive the first bitter taste of war?
