Dashiell Hammet (Continental Op) story?
This movie is the third in the Thin Man movie series.
The original is based, of course, on Hammet's novel of the same name (which was the only "Thin Man" yarn Hammet wrote).
The second movie appears to simply recycle the 3 lovable characters (including Asta) into a standard issue whodunnit.
Unlike "After the Thin Man", "Another Thin Man"'s credits state: "based on a story by Dashiell Hammet". Does this mean that the plot of this movie derives from an actual Dashiell Hammet story (besides the novel)?
The third movie seems more tautly constructed than the second one, which further suggests that possibility to me. This could be an adaptation of one or more "Continental Op" stories.
If so, what story is it?
