I didn't previously understand why the scene where Holmes discussed his cocaine use and the famous 7 percent solution wasn't filmed in this episode as in the Holmes canon but it became clear that it was because it was included in the first installment of the Granada series ("A Scandal in Bohemia").
Looming large in the denouement of this installment is the actor John Thaw (1942-2002) who was famous for playing Inspector (Endeavour) Morse in the original series and that explains my summary above.
It must also be mentioned that in the original Doyle story, Holmes reacts very badly to the news of Watson's impending marriage to Mary Morstan and, at the very end, he further reacts by reaching for his cocaine bottle but this is left unmentioned in the Grenada production.
Another scene, better done in the Doyle original, has to do with another appearance by Holmes in a surprising disguise which fools all people present but which is here rather abridged and also abridges the effectiveness of the scene.
This is also the episode where Holmes sends Watson to get his favorite dog Toby to help him in solving the mystery and also where he enlists the aid of his "Baker Street Irregulars" who actually seem more helpful, in the long run, than Toby, although they certainly upset Mrs. Hudson (As always Rosalie Williams) by invading their Baker Street household.
