The Complete Sherlock Holmes: The Heirloom Collection is indeed the complete collection of Sherlock Holmes stories by Arthur Conan Doyle. All four of his novels are included as are all of his short stories. From reading the novels and many of the short stories, one can discover exactly how Sherlock and Watson have become the beloved detective and sidekick that we know them as today. You can also see how some images or characteristics of the detective may be more accurate than others.
Admittedly, since the collection is almost sixty hours of listening I read not all of it but A Study in Scarlet, The Sign of Four, The Hounds of Baskerville, all of the Adventures of Sherlock Holmes, a few from the Memoirs of Sherlock of Holmes, including the one where he supposedly dies along with Moriarty, and the short story entitled The Empty House, which is the one in which he makes his triumphant return. It is my opinion that no adaptation or at least no adaptation of the 21st Century has gotten the character of Sherlock Holmes wholly correct. Some adaptations, especially the older ones, have painted him as simply serious crime solver. Some make him out to be an anti-social, strange inventor and boxer/badass (Sherlock Holmes movies of 2009 and 2011). Others turn him into a genius that is so weird that he could possible suffer from Asperger’s and couldn’t function without the help from Watson (BBC’s Sherlock). It is my impression that while many of these characteristics are based on Conan Doyle’s original Holmes that they are exaggerated depending on the focus or feel of the movie.
Summary: A farcical skewering of politicians, money and regular people trying to make a living.
Summary: Basis of the movie and beloved TV show, and well mined by them both for ideas.
Summary: A farce in the style of PG Wodehouse (or vice versa) poking fun at the triviality of Victorian society.
