What is Peter Blood in the novel, Captain Blood: His Odyssey?

Peter Blood is a scholar and doctor. He is a man of intellect, who is torn from his contemplative life and thrust into a life of bold action, though he seeks only to be left alone to pursue his quiet life and detach himself from the insanity of war. Against his will, Blood must confront injustice. Blood has the characteristic of being "an exceptional judge of men." He is self-sufficient, noble, and ruthless.
