Picking up the trail with the incredibly influential films of Basil Rathbone and Nigel Bruce, Volume II goes on to explore the antiheroic Sherlock Holmes films of the 1970s, and then the somewhat rocky journey of Holmes into the medium of television (actors Alan Wheatley, Douglas Wilmer, and Peter Cushing all declared their respective TV series as the worst experience of their professional careers).

Television finally found its "definitive" Holmes in Jeremy Brett's portrayal for Granada Television, and then the BBC's "Sherlock" had flashed brilliantly across the cultural sky before crashing and burning in spectacular fashion.

Still, despite its ignominious end, Benedict Cumberbatch's version of Sherlock Holmes quite literally changed the face of Sherlockian fandom overnight, as studious middle-aged white men now found themselves sharing uneasy ground with a younger, more diverse, and more female audience.

Now a full-fledged transmedia phenomenon, Sherlock Holmes can be any gender, ethnicity, or species, and is celebrated in fan fiction and fanvids, as well as conventions that are far more inclusive than Sherlock Holmes societies of the past.

Vincent Starrett's poetic notion that Sherlock Holmes is a character "who never lived and so can never die" has never been more true, and the Digital Age promises any number of new versions of Sherlock Holmes to come.
