But "Silent Doyle" actually refers to a brand new 4 part essay series from Howard Ostrom which examines the silent films adapted from Sir Arthur Conan Doyles non Sherlock Holmes related stories.
Howards latest venture came about after noted Sherlockian, Peter Blau, commented on his ‘Silent Sherlock’ essay series and mentioned; “I won't expect instant action on my suggestion that you also consider exploring silent films of Conan Doyle's non-Sherlockian works . . . there are some . . . "House of Temperley" and "Brigadier Gerard" and "The Fighting Eagle" among them, and I'm sure there is much more to be discovered.”
Never one to falter when it comes to research of the Sherlock Holmes universe and all subsequent extensions, Howard took to the challenge with gusto - the results of which you will be able to read over the next few days.
