Then terror came. On the night of September 24, 19 —, I heard a knock at my chamber door. Fancying it St John's, I bade the knocker enter, but was answered only by a shrill laugh. There was no one in the corridor. When I aroused St John from his sleep, he professed entire ignorance of the event, and became as worried as I. It was the night that the faint, distant baying over the moor became to us a certain and dreaded reality. Four days later, whilst we were both in the hidden museum, there came a low, cautious scratching at the single door which led to the secret library staircase. Our alarm was now divided, for, besides our fear of the unknown, we had always entertained a dread that our grisly collection might be discovered. Extinguishing all lights, we proceeded to the door and threw it suddenly open; whereupon we felt an unaccountable rush of air, and heard, as if receding far away, a queer combination of rustling, tittering, and articulate chatter. Whether we were mad, dreaming, or in our senses, we did not try to determine. We only realized, with the blackest of apprehensions, that the apparently disembodied chatter was beyond a doubt in the Dutch language. After that we lived in growing horror and fascination. Mostly we held to the theory that we were jointly going mad from our life of unnatural excitements, but sometimes it pleased us more to dramatize ourselves as the victims of some creeping and appalling doom. Bizarre manifestations were now too frequent to count. Our lonely house was seemingly alive with the presence of some malign being whose nature we could not guess, and every night that daemoniac baying rolled over the wind-swept moor, always louder and louder. On October 29 we found in the soft earth underneath the library window a series of footprints utterly impossible to describe. They were as baffling as the hordes of great bats which haunted the old manor-house in unprecedented and increasing numbers.
