Adelaide Adams, one of the best "nosy spinster" mystery protagonists from the 1930s is back in print after seventy-five years. Arkansas author Anita Blackmon's two Adelaide Adams detective novels, Murder a la Richelieu (1937) and There Is No Return (1938), have been reprinted by Coachwhip and are available through Amazon (by the way, if you are searching for Anita Blackmon by name on Amazon, note that she is NOT the author of the erotic novels by a modern author of the same name that are being offered on that website).
These are very enjoyable books by a very interesting woman (see my previous blog piece here). If you enjoy Mary Roberts Rinehart, Mignon Eberhart and Leslie Ford, you should enjoy Anita Blackmon. In both books there is also a five-page introduction by me, which I adapted from my blog article.
