I turned round at once, and saw, in the easy-chair which Harry had just vacated, a shadowy shape, which grew clearer and clearer the longer I looked at it. It was that of a man of forty, fashionably dressed in the costume of the year 1685 or thereabouts, and bearing a close resemblance to the faded portrait on the wall just opposite. But the striking point about the object was this, that it evidently did not consist of any ordinary material substance, as its outline seemed vague and wavy, like that of a photograph where the sitter has moved; while all the objects behind it, such as the back of the chair and the clock in the corner, showed through the filmy head and body, in the very manner which painters have always adopted in representing a ghost. I saw at once that whatever else the object before might be, it certainly formed a fine specimen of the orthodox and old-fashioned apparition. In dress, appearance, and every other particular, it distinctly answered to what the unscientific mind would unhesitatingly have called the ghost of Algernon Egerton. Here was a piece of extraordinary luck! In a house with two trained observers, supplied with every instrument of modern experimental research, we had lighted upon an undoubted specimen of the common spectre, which had so long eluded the scientific grasp. I was beside myself with delight. "Really, sir," I said, cheerfully, "it is most kind of you to pay us this visit, and I'm sure my friend will be only too happy to hear your remarks. Of course you will permit me to call him?" The apparition appeared somewhat surprised at the philosophic manner in which I received his advances; for ghosts are accustomed to find people faint away or scream with terror at their first appearance; but for my own part I regarded him merely in the light of a very interesting phenomenon, which required immediate observation by two independent witnesses. However, he smothered his chagrin--for I believe he was really disappointed at my cool deportment--and answered that he would be very glad to see my friend if I wished it, though he had specially intended this visit for myself alone. I ran upstairs hastily and found Harry in his dressing-gown, on the point of removing his nether garments. "Harry," I cried breathlessly, "you must come downstairs at once. Algernon Egerton's ghost wants to speak to you." Harry held up the candle and looked in my face with great deliberation. "Jim, my boy," he said quietly, "you've been having too much whisky." "Not a bit of it," I answered, angrily. "Come downstairs and see. I swear to you positively that a Thing, the very counterpart of Algernon Egerton's picture, is sitting in your easy-chair downstairs, anxious to convert you to a belief in ghosts."
