Feeling that I could not sleep any more I got up. I had hung my shaving mirror by the window, and was just beginning to shave. Suddenly I felt a hand on my shoulder and heard Count Dracula's voice greeting me. I started, for I had not seen him, though the reflection of the glass covered the whole room behind me.
In starting I had cut myself slightly, but did not notice it at the moment. I looked into the mirror again to see if I was mistaken. This time there could be no error, for the man was close to me, and I could see him over my shoulder. But there was no reflection of him in the mirror! I saw the whole room behind me; there was not a sign of man in it, except myself.
At that moment I saw that I had cut myself and the blood was trickling over my chin. Turning round, I laid down the razor. When the Count saw my face, his eyes blazed and he suddenly made a grab at my throat. I drew away, and his hand touched the crucifix which I have round my neck. He withdrew his hand, as if he had touched a hot piece of metal and his fury passed so quickly I could hardly believe that it had ever been there.
