Abraham Lincoln came to the presidency under a heavy shroud of uncertainty, not only about his threatened life but, of course, the very existence of the United States, which was already falling apart. Ward Hill Lamon was, in effect, his first Secret Service agent, his security guard and this biography, heavily edited by his daughter, Dorothy Lamon sets down for posterity many details surrounding Lincoln's near-fatal journey to his inauguration, how he dealt with day to day presidential decisions and a wide range of interpersonal relationships with the visionaries, schemers and power brokers surrounding him. - Summary by John Greenman
