Exciting news for lovers of classic mysteries: Amazon will be republishing all 49 of Leslie Charteris's books featuring the character Simon Templar, known as "The Saint," as well as all 65 of the Mrs. Bradley books by Gladys Mitchell along with six of her other books that do not feature Mrs. Bradley.
Although I don't think I have ever read any of the original books, I remember The Saint from the series of "B" movies which were always on television when I was growing up, often featuring George Sanders in the title role. And I've written here - frequently - about some of the Mrs. Bradley mysteries, many of which have never been published in the U. S.
Apparently these will start appearing sometime later this year, under Amazon's Thomas & Mercer imprint.
