I knew the hand, and I knew the revolver, and I knew the quickness of both. I did not say a word or make a sound, till Marjory with an alert movement seemed to sweep up out of the opening and whirled round with ready pistol, as though suspecting an enemy on every side.

Marjory, all covered with dust, her cheeks as white as snow, so that the smears of dust lay on them like soot; and eyes with pupils distended as in coming from the dark. For a few seconds she seemed hardly to recognise me; but when she did she sprang gladly into my arms.

“Oh! Archie, I am glad to see you. It was so terrible and lonely in the dark. I began to fear I might never find my way out!” In the dark! I began to fear, and asked her:

“But, dear one, how did you come; and why? Hadn’t you got a light with you? Surely you didn’t come unprepared, if you did venture into the cave!” Then in a rush she told me the whole story. How before dawn she had been waked by the dropping of the book and had hurried to the castle roof to watch the stone. With her field glass she had presently seen it move. She was then satisfied that the watchers had gone home; and had determined on a little adventure on her own account.

“I put on a grey tweed dress, and taking my revolver and bicycle lamp, stole out of the castle and reached the old chapel. Having lit my lamp, I rolled back the stone and set out to explore the tunnel. I followed from your description, the passage to its bifurcating, and determined to explore the other arm to the reservoir. I easily found it, a deep, dark tank cut in the rock and seemingly fed by springs which bubbled up from patches of fine sand, the accumulation of years of wasting rock. Whilst I was trying to look into the depth of the reservoir, holding my bicycle lamp so as to throw its light downwards, I saw something white at the bottom. Just then the lamp from its inverted position began to smoke, but as I looked in that last moment through the crystal pure water I recognised that the white object was a skull. In the sudden shock of the discovery, the lamp dropped from my hand and disappeared hissing and bubbling in the last flicker of light.” As she told me this, I took her hand for I feared that the memory of such an appalling moment must have unnerved her; but to my surprise her nerves were as firm as my own. She let her hand remain in mine; but she had evidently understood my thought for she said:

“Oh! it’s all right now, Archie. For a moment or two I do believe I was frightened. You can have the laugh on me there if you like! But then common sense came to my aid. I was in a tight place, and it would need all I knew to get out. I thought the matter over as coolly as I could; and do you know that coolness seemed to grow with the effort! I was in the dark, in a cave, deep underground, the entrance to which was secret; I had no means of getting a light even for an instant, for though I had taken plenty of wax matches they were all in my lamp. The only thing I could do was to try to grope my way out. I had noted the passage as I came along, but I found so soon as I had felt my way out of the reservoir chamber, how little use an abstract recollection is when every second there is a new detail. I found, too, the astonishing difference between sight and touch; what I had remembered had been with my eyes and not with my fingers. I had to guard all round me, my head, my feet, my sides. I am amazed, now when I think of it, how many different kinds of mistakes and calculations I made in a few yards. It seemed a terribly long time till I came to the place where the passage forks. There I weighed up the matter of whether it would be better to go back by the way I had come to the old chapel, or to go up the other passage to the monument of which you told me. Somehow the latter seemed to me the more feasible. I think it must have been that I trusted you more than myself. You had not shrunk from going into that passage; and I would not shrink from going out.”

I squeezed her hands hard, I had got both by this time. She blushed a little and looked at me fondly and went on:

“There was something cheering in the mere fact of going up instead of down. It was like coming towards the air and light again; and the time did not seem so long till I came to the end of the passage, for so far as I could feel there was nothing but solid rock all round me. For a little bit my heart sank again; but I soon bucked up. I knew that this must be the way out; and I felt around for the iron handles of which you had told me. And then, Thank God for His goodness! when the stone began to turn I saw the light, and breathed fresh air again. They seemed to give me back all my courage and caution. Up to this I had not troubled about kidnappers; there was quite enough to think of in getting along the passage. But now I was my own woman again, and I determined to take no chances. When I saw it was your gun that was aimed at me I was glad!”
