So all the transcripts - from A Study in Pink (both the broadcast version and the pilot), all the way through Many Happy Returns and the Special, right the way up to and including The Final Problem - are now downloadable as Word or PDF files.
There’s a file of all the transcripts in their entirety; a file of just the speaker and spoken words in every episode; and a file giving all the words spoken by 27 individual characters listed together, e.g. every line spoken in all episodes by Mycroft, or by John, or by Mrs Hudson etc.
And for those people who have already got heavily annotated/edited earlier versions of the transcripts, there are also Season 4 only versions of the full transcripts and of the speakers and spoken words.
