Dracula by Bram Stoker Chapter 5 Page 5

He is a doctor and really clever. Just fancy! He is only nine-and twenty, and he has an immense lunatic asylum all under his own care. Mr. Holmwood introduced him to me, and he called here to see us, and often comes now. I think he is one of the most resolute men I ever saw, and yet the most calm. He seems absolutely imperturbable. I can fancy what a wonderful power he must have over his patients. He has a curious habit of looking one straight in the face, as if trying to read one's thoughts. He tries this on very much with me, but I flatter myself he has got a tough nut to crack. I know that from my glass.

Do you ever try to read your own face? I do, and I can tell you it is not a bad study, and gives you more trouble than you can well fancy if you have never tried it.
