Query: Alone, alone, alone

Most of the text of this fascinating novel involves the adventures of one man who is absolutely alone in the world. It is not everyone who can handle a novel with only one character, and this a character who of necessity must be insane. Shiel manages to deal with this very well. He mitigates the horror by having the millions of dead bodies fail to rot or stink. The ending is rather sentimental. It might have been more effective if Adam had not met his Eve.
