round the opening, being very careful not to press hard enough to break the wall-paper, and then went into the adjoining room to study the doorway from that side. The same neat, careful job had been made, and she now noted more particularly a fact which had struck her before—that the opening from the passage leading into this smaller room was not, and never had been, a doorway in which to hang a door— it was merely an arch which had been formed by removing bricks from the passage wall.
Whether these alterations had any sinister implication still had to be discovered. She noted them, and passed on. The attics, which she thought might repay inspection, proved disappointing in that they were entirely empty. Whatever lumber the house might once have harboured was not now on this top floor. She inspected the boards closely. They were dusty, but not unduly so, and she supposed that these rooms, in common with the other parts of the house to which the public were not usually admitted, received attention at intervals from the caretaker and his daughter. There was an absence of cobwebs which suggested that the last cleaning of the attics had been of fairly recent date.
She walked over to the window in each room and looked out, but beyond an extended view of the country around the house, the windows had nothing to offer. She tested the catches. They were rusty, and it did not seem as though the windows could have been opened for some considerable time, certainly not when the rooms had last been cleaned.
The attics did not cover the whole of the floor beneath, but belonged, it seemed, to the older part of the present structure, for the rooms on the opposite side of the house had no attics built over them. The lower roofs could be seen from two of the attic windows. The courtyard could not be seen from any of the upstair windows except the shuttered window on the stairs.
She was about to descend the narrow stairs when she noticed what seemed to be ventilation holes in the partition wall at the top of the staircase. When the attic doors were shut this partition wall was in darkness. She looked back, and saw that one of the doors which she believed she had shut and locked was swinging slowly open.
With a feeling more of interest than of anything approaching alarm, she went back to find out what had happened. She had not anticipated anything in the way of a supernatural occurrence, but she was relieved, all the same, to discover that the trouble was due to a defective lock and did not emanate from the realm of the spirits.
She pushed the door wide open, and went back to examine the air-holes. It was now obvious that they ventilated a large cupboard, or small, unlighted room, on the opposite side of the passage. The door of it had been papered over to match the rest of the decorations of the attic corridor, and again, like the door into the dressing-room on the floor below, would, in the ordinary-way, pass unnoticed. She traced the outline of the door beneath the paper, closed the attic door again, and this time, fastened it securely, and then, with some part of her theory if not proved, at any rate capable of proof, she returned to the first floor and made an exhaustive search.
Nothing further was to be discovered there, however, and she spent the next three-quarters of an hour in checking the plan of the house which formed the only illustration to the little guidebook she had purchased on her previous visit, and in preparing a sketch-plan of her own on which she marked the door with the faulty lock, the position of the two attic cupboards, the blocked-up and papered-over communicating door between the largest bedroom, and the window with the inside shutters and the dressing-room at the top of the stairs.
Her next objective was the courtyard. This was a rectangular strip of garden which had been made almost into a quadrangle by the addition of the newest wing. It was overgrown with tall weeds, the willow-herb flourishing particularly. There was a well at one corner, close to the scullery door. A couple of boards formed the cover. She removed them, peered into the well and then replaced the boards.
Although it was broad daylight, the courtyard looked eerie and desolate. It was silent, too, and the surrounding buildings seemed to
