The Rivals of Sherlock Holmes, Vol. 1 - Various

The Rivals of Sherlock Holmes was a British TV series from the early 70s that dramatized stories written contemporaneously with the Sherlock Holmes stories of Sir Arthur Conan Doyle. This anthology contains twelve of the thirteen stories adapted as episodes for the first season. Sadly, one story, "The Missing Witness Sensation" by Ernest Bramah, is not public domain in the U.S., but can be read in the anthology Max Carrados Mysteries. (Summary by Nullifidian)
