Three wartime era novellas (1942) that Charteris wrote while he was in America make up The Saint Goes West. The first one, "Arizona," is the least effective of the bunch, for me, because it seems so much like a duded up Western from the 1940s, which it was, of course. While the trappings of the Western and Cowboy slang with rootin' tootin' six-shooters and all make me wince, the story itself is pretty good--Nazi agents taking over a mineral deposit used for making munitions. In fact, the story plays much better in the Roger Moore television version, which occurred during season three of The Saint. There the story was shifted to Southeast Asia (alluding to the Malayan Emergency, which had just ended) and replaced Nazis with Communist agents. The jungle terrain and iconography works much better than the book's Western locale.
The next two novellas are a notch above, especially "Hollywood," which is the best hard-boiled/noir effort I've so far read in the series. Punchy, dark, violent and peppered with quips and jargon that could have come out of The Big Sleep. This story, too, was made into an episode with Roger Moore. But the television version is far inferior to Charteris' book version. It's set in the UK and focused on the UK film industry instead of Hollywood. It's far weaker fare. The middle story, "Palm Springs," is a nice compromise between both "Arizona" and "Hollywood," as its setting in the California wilderness still makes use of some Western motifs as well as Hollywood celebrity. A dandy in the Old West might see the connections with Simon's eventual villain in this tale.
