The Adventure of the Noble Bachelor turns out to be one of the easiest cases for Sherlock Holmes to deal with; with the detective having dealt with similar problems in the past. Indeed, Holmes had solved the case even before the client, Lord St Simon, has departed from Baker Street.
The basic problem is that Hatty Doran, the new wife of Lord St Simon, has disappeared, and foul play is suspected. Some suspicion is placed on Lord St Simon, as he had a financial motive, but also suspected is an old flame of Lord St Simon, Flora Miller.
Holmes offers a full explanation to Inspector Lestrade, but just as in the case of The Boscombe Valley Mystery, the detective doesn’t take Holmes seriously, so Holmes feels empowered to deal with the case in the best way he sees fit.
The Adventure of the Noble Bachelor is an example of where a case for Sherlock Holmes doesn’t necessarily mean that there is a crime, and this is perhaps why the story is less memorable than many others within the Conan Doyle canon of works.
The story was adapted by Granada Television, with Jeremy Brett starring as Sherlock Holmes. The episode, titled The Eligible Bachelor, made a number of plot changes, something which was strange for the television, which normally kept close to the original storylines.
