I read the entire 2000 page omnibus and discovered a quite good writer. His attention to detail is exceptional and each of his novels, or novellas, contain reasonable mystery stories though some are a little stretched for logic. His main weakness is the characters of women whom he doesn't seem to understand. All of them are basically cut from the same mold: beautiful, tough, rich, sexual... all good, but all the same except perhaps for hair colour. He really is an early formula writer like so many of today and obviously succeeded in attracting fans. I would recommend this, but not all at once.
