This book is my new favourite after the hound of the baskervilles but after all it was a much darker story...Holmes truly shows us what a great detective he is by thinking from the perspective of the criminal when he tracks them down. The chase on the Thames is truly one of my favourite moments in the book.One can truly visualise and feel the tension crackling high in these moments. this racy, well written story is best suited for those who like treasure hunt-based stories.
