Return to a time when a man's honor is the most precious thing he possesses, his word the one thing he will never break. The Vacant Chair, a Civil War mystery, pits honor against the dictates of duty and the reverence due family when a Union soldier risks everything to shield a Confederate prisoner from paying for the crimes of a man who'll do anything to protect his family's honor -- even kill his own brother.
When the endless tedium of winter camp is shattered by murder, Union Lieutenant Jack Logan will put his command, his freedom, and ultimately his life on the line in his determination to discover which of his men is a faithless murderer. Unlike his superior officers, Jack doesn't see anything just about hanging a Rebel prisoner for the crime when there's not a shred of evidence against him. A spy he might be, but a murderer? That remains to be seen. Jack's defense of the Rebel proves as hazardous as the investigation he undertakes against orders. Between them, the murderer and the men Jack is expected to obey strip away everything Jack holds dear as he struggles to understand what besides the necessities of war can bring one man to kill another. Before he's done, Jack will discover his best ally in an enemy prisoner and his worst nightmare in the eyes of one of his own men. And that sometimes, what is just and what is honorable are two very different things.
This is blather. Be specific. You're talking in cliches. Give me three specific actions, and the decision he has to make.
I'd actually be interested in reading abook that says "what is just and what is honorable are two very different things" but you're going to have to hook me with some specifics first.
