I gave up trying to think and turned resolutely away. As I did so the knocking began again upon the window-pane. "Do stop; oh! don't go away. Stop! stop!" it seemed to call after me insistently as I quickened my footsteps and gradually outdistanced the imperious demand. What explanation have I to offer? None! The hallucinations of a tired woman? That may do for the general public, but not for me. You see, I was the person who heard it. There are many haunted houses that are quite habitable, such as Hampton Court Palace, etc. Where the apparition keeps strictly to an anniversary, or where the phenomena are mild and inoffensive, their presence can be endured with a certain amount of equanimity. The point really lies in this. Are the ghosts who haunt a dwelling indifferent to, or hostile to, the presence of their companions in the flesh? If the situation is according to the latter, then the ghosts will certainly score. They will rid themselves of the human inhabitants by a wearing-down nerve pressure, which cannot be fought against with any chance of success. If the ghosts are shy or indifferent, wrapped up in their own concerns and containing themselves in a world of their own, then there is no reason why the incarnate and discarnate should not live peacefully together. To-day, February 27th, 1919, I read the following in the _Morning Post_:-- "Haunted or disturbed properties. A lady who has deeply studied this subject and possesses unusual powers will find out the history of the trouble and undertake to remedy it. Houses with persistent bad luck can often be freed from the influence. Strictest confidence. Social references asked and offered." What would our grandparents have thought of this means of turning an honest penny? I have no doubt the lady "possessing the unusual powers" will be employed, and in many cases she will be successful. In the majority of cases I venture to say that she will fail, simply because the majority of cases are too elusive to be dealt with by human means. How would this lady treat the "Castel a Mare" scream? How would she deal with the next story I am going to relate? It is a simple matter to compile a book of thrilling ghost stories if direct evidence is not given, if names of persons and places are suppressed. I claim that my stories have a special interest and value, because I have tried to restrict them to such as can be attested to by living persons, closely related to me either by friendship or by family ties. In a very few instances I have been obliged for obvious reasons to suppress the names of houses and hotels. In these cases I am ready personally to supply full information to genuine students of the occult, if they are willing to approach me privately. CHAPTER XXII THE HAUNTED LODGE A considerable number of people are alive who can testify to the truth of the facts I now narrate. I regret that I have not been able to investigate this case personally, but I hope to do so before very long.
