Excerpt
If I didn’t tell this, nobody else ever would; certainly not Diana, nor Major Vandyke—still less Eagle himself—I mean Captain Eagleston March; and they and I are the only ones who know, except a few such people as presidents and secretaries of war and generals, who never tell anything even under torture. Besides, there is the unofficial part. Without that, the drama would be like a play in three acts, with the first and third acts chopped off. The presidents and secretaries of war and generals know nothing about the unofficial part.
