Major Andrew Forester is a retired British Army officer, of no discernible occupation, who wanders about Europe, England and the United States in the 1920s. He is looking for adventure, but not outside the bounds of the acceptable. He is willing to skirt the law, but not break it. A bachelor, he has been unsuccessful in love, with a limited income. He stays in out-of-the-way hotels, and smaller pensions, and takes an occasional gamble on the tables at Monte Carlo. His peripatetic life style brings him in contact with scam artists, gold-diggers, art thieves, industrial spies,taxi dancers, and flappers. Sometimes he benefits from these associations, but at other times he is their victim. He does this all with style, impeccable clothing, and a humorous tolerance of human failings. The title is, I think, a reference to a common phrase used to catch up with the news of old friends or acquaintances: "whatever happened to old so and so"? After WW1, many British officers, often the younger sons of wealthy families, were retired from the Army, some on "half-pay" which was barely adequate for living in society. Some of these wandered Europe looking for opportunities, or wealthy wives. So it is with Forester.
