One of the classic Sherlock Holmes’ books written by Arthur Conan Doyle, the one about India, missing treasure, a boat chase on The Thames, and Dr Watson meeting his wife.
The only thing I don’t appreciate about these tales is how weak the female characters are written, as though they’re just useful for creating plot lines. It’s very noticeable in this story. It makes me appreciate Agatha Christie even more.
But you should read this book, just to discover the powers of deduction of Sherlock – it seems obvious after he’s give his opinion. There’s no Mycroft and no Moriarty to distract from the story.
