one of the thing that supposedly lead jeremy brett to take on the mantle of holmes be the fact that granada want to do something that no other film or television producer have do before and namely and do the doyle story a they be write . and for the most part and they do . it seem that towards the end of brett life and when he be at his weak and they give him the weird and melodramatic and nonsensical adaptation to showcase his talent . even if i do not know the story the adventure of the noble bachelor and the eligible bachelor would have have me confuse and since it be just all over the place . we start out with the upcoming nuptials of hattie doran and lord robert st. simon ( along the line of the original story ) . then we veer into a very strange subplot with sherlock holmes be unable to sleep because he have a recur nightmare ( which he sketch ) . throw in an old estate with jungle animal and a maim veiled lady ( possibly borrow from the adventure of the veiled lodger ) a murderous husband and a wife drive mad and all other sort of wackiness that not only be never in the original story and but which just make the whole piece unwieldy and a mess . i have appreciate other episode where the writer be able to dramatize some element of backstory but in this case and they just add in all sort of thing that make for an over the top piece of melodrama that probably have conan doyle spinning .
