The Professor inhabited the northern wing, reputed to have been the original lodge in which kings and queens and great soldiers and statesmen had held revel after the chase, and tradition had endowed it with a quite authentic ghost: which was that of a fair maiden who had been decoyed thither to become the victim of royal passion, and who, strangely enough, poisoned herself in her despair, instead of getting herself made a duchess and founding the honours of a noble family on her own dishonour. Although, as I have said, quite authentic, for the Professor had seen her so often that he had come to regard her with respectful friendship, the Lady Alicia was not quite an orthodox ghost. She did not come at midnight and wail in distressing fashion over the scene of her sad and shameful death. She seemed to come when and where she listed, whether in the glimpses of the moon or the full sunlight of mid-day. She never passed beyond the limits of the old lodge, and never broke the silence of her coming and goings. None of the present inhabitants of "The Wilderness" had seen her save the Professor, but Nitocris had often shivered with a sudden chill when she chanced to be in her invisible presence, and at such times she would often say to her father: "There is something cold in the room, Dad. I suppose your friend the Lady Alicia is paying you a visit. I _do_ wish she would allow me to make her acquaintance." And to this he would sometimes reply with perfect gravity: "Yes, she has just come in: she is standing by the window yonder." And this had happened so often that Nitocris, like her father, had come to regard the wraith, or astral body, as the Professor deemed it, of the unhappy lady almost as a member of the family. Of course, after he had passed the border into the realm of N4, Franklin Marmion speedily came to look upon her visits as the merest commonplaces. But as the unhappy Lady Alicia will have no part to play in the action of this narrative, her little story must be accepted as a perhaps excusable digression. There were about four acres of comfortably wooded land about the house, of which nearly an acre had formed the pleasaunce of the old lodge. This was now a beautifully-kept modern garden, with a broad, gently-sloping lawn, whose turf had been growing more and more velvety year by year for over three centuries, and divided from it by a low box-hedge was another, levelled up and devoted to tennis and new-style croquet. The Old Lawn, as it was called, sloped away from a broad verandah which ran the whole length of the central wing and formed the approach to the big drawing-room and dining-room, and a cosy breakfast-room of early Georgian style, and these, with her study and "snuggery" and bedroom on the next floor, formed the peculiar domain of Miss Nitocris.
