The story was later adapted in 1986 as an episode of "The Return of Sherlock Holmes" starring Jeremy Brett. The episode is rather faithful to Doyle's story, except that Moran tries to shoot Holmes in Switzerland instead of dropping boulders on him, and it is Watson – not Holmes – that deduces the reason that Moran had for killing Ronald Adair. It was the first episode to feature Edward Hardwicke as Dr Watson, replacing David Burke who had played the role in the preceding episodes (Hardwicke reenacted a scene from "The Final Problem" in a flashback, consisting of Watson at the waterfall shouting to Holmes and reading his letter, which had been performed by Burke).
