This is a very odd book indeed. A son's somewhat episodic history of his father, a man I don't think he particularly loved or even liked. The episodes are interesting in themselves and very well set, but without a through line, it is hard to get one's head around his character. And that may be the point. Sons don't really know their fathers' lives, just what they glimpsed or heard tell of as anecdotes from dad or his friends.
The writing is quite good and the author is the nephew by marriage of Anthony Powell whose Dance to the Music of Time is equally episodic, but somehow hangs together of its 12 books more coherently that this 250 page novel did for me. Still, I found myself wanting to keep reading it for the good bits and hoping that a theme would emerge and yet not dissatisfied when none did.
Also, this is the first novel in a series Mount called A Chronicle of Modern Twilight.
