The Hound of the Baskervilles1939

Sherlock Holmes:
There are still some gaps to be filled, but all in all, things are becoming a little clearer.

Dr. Watson:
Not to me, I assure you; it's all a hopeless jumble. Stapleton, Franklin, the Barrymans - put it all together and what have you got?

Sherlock Holmes:
Murder, my dear Watson. Refined, cold-blooded murder.

Dr. Watson:
Murder?

Sherlock Holmes:
There's no doubt of it in my mind. Or perhaps I should say, my imagination. For that's where crimes are conceived and they're solved - in the imagination.
