The Valley of Fear Quote by Sir Arthur Conan Doyle

All else in the man, his noble proportions, his fine features, and his frank bearing, fitted in with that jovial, man-to-man manner which he affected. Here, one would say, is a bluff, honest fellow, whose heart would be sound however rude his outspoken words might seem. It was only when those dead, dark eyes, deep and remorseless, were turned upon a man that he shrank within himself, feeling that he was face to face with an infinite possibility of latent evil, with a strength and courage and cunning behind it which made it a thousand times more deadly. ~ The Valley of Fear
