Rather than questioning the butler, the next logical step in the novel, Watson and Sir Henry set off to find the other end of the chain of signals. This leads to a confrontation with Selden, who throws a boulder at them, and they hear the baying of the hound. Watson also gets a glimpse of the mysterious “man on the tor,” a horribly bungled shot of someone moving through the studio undergrowth. What we needed was an approximation of Paget’s evocative illustration for The Strand, which would have been child’s play to achieve.
Back at the Hall the Barrymores confess: Selden is their relative, and they plead for him to be allowed to escape to South America. In the novel Watson condones this appalling notion on the grounds that it will “relieve the taxpayer of a burden.” Here his agreement is made more excusable because the murderous Selden has been rendered harmless by an operation on his brain. When we see him he certainly looks like a survivor of the Victor Frankenstein School of Surgery, but still not exactly the Notting Hill pussy-cat. But why, I wonder, was Selden in Dartmoor in the first place? If he escaped the hangman on mental grounds, surely he would have been 200 miles away in Broadmoor, which was established in 1863 as a secure hospital for the criminally insane.
On the following day Sir Henry gives Barrymore some of his discarded clothes, although he must realise that they will incriminate him if Selden is caught. He does not, of course, realise that he is condemning the man to death. While Sir Henry sets out to visit Beryl Stapleton, we see Holmes on a train and hear the guard announcing, “London next stop.” Curiouser and curiouser. Sir Henry’s courtship is interrupted by a furious Stapleton and watched by Watson, a sequence from the novel which has been repositioned and expanded. In London, for no very good reason, Holmes sets off for the Royal Observatory. Watson’s letters are still being withheld and we next see Holmes back in Baker Street. Then, in a shot borrowed from The Greek Interpreter, we see him on a railway station platform again. What on earth is going on here?
In Devon events follow a more familiar pattern. Barrymore reveals that a note signed L.L. led Sir Charles to his death and Watson identifies Frankland’s estranged daughter, Laura Lyons, as the sender. Frankland himself points out a spot on the moor to which a child is taking food; Watson investigates and meets Mortimer, who is conducting an archaeological dig nearby. The two men lie in wait for the mystery man, who is using a cave as his hiding place.
Holmes reveals himself and, when Mortimer has gone, he and Watson compare what they have learned about the plot against the Baskervilles. As an apology for deceiving Watson about his whereabouts, Holmes offers him some of his home-made stew, which, in an affectionate nod to a similar moment in The Priory School, Watson describes as “quite disgusting.” Their discussion is interrupted by a fearful commotion outside the cave, and, in the best action sequence in the film, we see Selden fall to his death pursued by the hound.
There are some minor changes here. Holmes has identified Stapleton as the villain (and Beryl as his wife), but Stapleton is not involved in concealing the death of Selden, for instance. The most important is that we are denied Watson’s interrogation of Laura Lyons. Edward Hardwicke, who pays a perfect Watson in a story which puts him at the centre of the stage, deserved to have that scene. Instead the two interviews with the lady are combined into one and, because he has been away so long, Holmes gets the bulk of the dialogue.
Quite understandably, Lestrade is omitted from our version and is replaced at the climax by Mortimer. Sir Henry dines with Stapleton, Beryl is bound and gagged, the luminous hound is abroad. Holmes just manages to shoot the dog before it does serious injury to its victim, and the battered Miss or Mrs Stapleton is released. As Stapleton loses his footing and dies in the Grimpen Mire, we are left to wonder whether or not his widow will one day become Lady Baskerville. Back in London, Watson ties up the loose ends before being whisked off to the opera by Holmes, who apparently drives his own carriage to Covent Garden for the occasion.
To complete the record, our main location was Heath Hall in Staffordshire, but much of the moor was reconstructed in Granada’s Stage One, now the permanent home of Coronation Street. Our hound was a Great Dane called Khan, whose glow was supplied in the laboratory by a special optical effect, rather like Eille Norwood’s hound in the 1921 film, which was hand-painted frame by frame.
