Dracula's Guest

"Tell me, Johann, what is tonight?"

He crossed himself, as he answered laconically: "Walpurgis nacht." Then he took out his watch, a great, old-fashioned German silver thing as big as a turnip and looked at it, with his eyebrows gathered together and a little impatient shrug of his shoulders. I realized that this was his way of respectfully protesting against the unnecessary delay and sank back in the carriage, merely motioning him to proceed. He started off rapidly, as if to make up for lost time. Every now and then the horses seemed to throw up their heads and sniff the air suspiciously. On such occasions I often looked round in alarm. The road was pretty bleak, for we were traversing a sort of high windswept plateau. As we drove, I saw a road that looked but little used and which seemed to dip through a little winding valley. It looked so inviting that, even at the risk of offending him, I called Johann to stop--and when he had pulled up, I told him I would like to drive down that road. He made all sorts of excuses and frequently crossed himself as he spoke. This somewhat piqued my curiosity, so I asked him various questions. He answered fencingly and repeatedly looked at his watch in protest.

Finally I said, "Well, Johann, I want to go down this road. I shall not ask you to come unless you like; but tell me why you do not like to go, that is all I ask." For answer he seemed to throw himself off the box, so quickly did he reach the ground. Then he stretched out his hands appealingly to me and implored me not to go. There was just enough of English mixed with the German for me to understand the drift of his talk. He seemed always just about to tell me something--the very idea of which evidently frightened him; but each time he pulled himself up saying, "Walpurgis nacht!"

I tried to argue with him, but it was difficult to argue with a man when I did not know his language. The advantage certainly rested with him, for although he began to speak in English, of a very crude and broken kind, he always got excited and broke into his native tongue--and every time he did so, he looked at his watch. Then the horses became restless and sniffed the air. At this he grew very pale, and, looking around in a frightened way, he suddenly jumped forward, took them by the bridles, and led them on some twenty feet. I followed and asked why he had done this. For an answer he crossed himself, pointed to the spot we had left, and drew his carriage in the direction of the other road, indicating a cross, and said, first in German, then in English, "Buried him--him what killed themselves."

I remembered the old custom of burying suicides at cross roads: "Ah! I see, a suicide. How interesting!" But for the life of me I could not make out why the horses were frightened.
