This is probably the best of the Holmes vels. Like all of them (and the short stories) it is near impossible to put down, and leaves you awestruck at Holmess genius. Doyles writing style is extremely impressive as always, his characters seem so very real! Perhaps the best Sherlock Holmes story of them all. Subtle and devious. If you think you kw it or have read something like it before - thats because almost every mystery writer since has copied in some way directly or indirectly. This book is believable, a true masterpiece of mystery literature, and in the top tier of the long list of the great English detective stories. It just doesnt get any better than this. Even the long section without Holmes and Watson in it (The Scowers) is enjoyable to read, and t boring. Highly reccommended.
