I luckily had some vestas in the little silver box which I always carry on my watch-chain, and striking one I relit the lantern. Clinton's paroxysm was over, and sinking to the floor he lay there shivering and cowering.

It was a terrible situation, and I knew that our only hope was for me to keep my presence of mind. With a great effort I forced myself to think calmly over what could be done. To shout for help would have been but a useless waste of breath.

Suddenly an idea struck me. "Have you got your father's letter?" I cried eagerly.

"I have," he answered; "it is in my pocket."

My last ray of hope vanished. Our only chance was that if he had left it at the house some one might discover the letter and come to our rescue by its instructions. It had been a faint hope, and it disappeared almost as quickly as it had come to me. Without it no one would ever find the way to the vault that had remained a secret for ages. I was determined, however, not to die without a struggle for freedom. Taking the lantern, I examined every nook and cranny of the cell for some other exit. It was a fruitless search. No sign of any way out could I find, and we had absolutely no means to unfasten the door from the inner side.

Taking a few short steps, I flung myself again and again at the heavy door. It never budged an inch, and, bruised and sweating at every pore, I sat down on the coffin and tried to collect all my faculties.

Clinton was silent, and seemed utterly stunned. He sat still, gazing with a vacant stare at the door.

The time dragged heavily, and there was nothing to do but to wait for a horrible death from starvation. It was more than likely, too, that Clinton would go mad; already his nerves were strained to the utmost.

Altogether I had never found myself in a worse plight.

It seemed like an eternity that we sat there, neither of us speaking a word. Over and over again I repeated to myself the words of the terrible curse: "And whoso entereth into the cell shall be the prisoner of the soul that guardeth the door till it shall let him go." When would the shapeless form that was inside the coffin let us go? Doubtless when our bones were dry.

I looked at my watch. It was half-past eleven o'clock. Surely we had been more than ten minutes in this awful place! We had left the house at eleven, and I knew that must have been many hours ago. I glanced at the second hand. _The watch had stopped._

"What is the time, Clinton?" I asked. "My watch has stopped."

"What does it matter?" he murmured. "What is time to us now? The sooner we die the better."

He pulled out his watch as he spoke, and held it to the lantern.

"Twenty-five minutes past eleven," he murmured dreamily.

"Good heavens!" I cried, starting up. "Has your watch stopped, too?"

Then, like the leap of a lightning flash, an idea struck me.

"I have got it; I have got it! My G.o.d! I believe I have got it!" I cried, seizing him by the arm.

"Got what?" he replied, staring wildly at me.

"Why, the secret--the curse--the door. Don't you see?"

I pulled out the large knife I always carry by a chain and swivel in my trouser pocket, and telling Clinton to hold the lantern, opened the little blade-saw and attacked the coffin with it.

"I believe the secret of our deliverance lies in this," I panted, working away furiously.

In ten minutes I had sawn half through the wooden edge, then, handing my tool to Clinton, I told him to continue the work while I rested. After a few minutes I took the knife again, and at last, after nearly half an hour had gone by, succeeded in making a small hole in the lid.

Inserting my two fingers, I felt some rough, uneven ma.s.ses. I was now fearfully excited. Tearing at the opening like a madman, I enlarged it and extracted what looked like a large piece of coal. I knew in an instant what it was. It was magnetic iron-ore. Holding it down to my knife, the blade flew to it.

"Here is the mystery of the soul," I cried; "now we can use it to open the door."

I had known a great conjurer once, who had deceived and puzzled his audience with a box trick on similar lines: the man opening the box from the inside by drawing down the lock with a magnet. Would this do the same? I felt that our lives hung on the next moment. Taking the ma.s.s, I pressed it against the door just opposite the hasp, and slid it up against the wood. My heart leapt as I heard the hasp fly up outside, and with a push the door opened.

"We are saved," I shouted. "We are saved by a miracle!"

"Bell, you are a genius," gasped poor Clinton; "but now, how about the stone at the end of the pa.s.sage?"

"We will soon see about that," I cried, taking the lantern. "Half the danger is over, at any rate; and the worst half, too."

We rushed along the pa.s.sage and up the stair until we reached the top.

"Why, Clinton," I cried, holding up the lantern, "the place was not shut at all."

Nor was it. In his terror he had imagined it.

"I could not see in the dark, and I was nearly dead with fright," he said. "Oh, Bell, let us get out of this as quickly as we can!"

We crushed through the aperture and once more stood in the chapel. I then pushed the stone back into its place.

Dawn was just breaking when we escaped from the chapel. We hastened across to the house. In the hall the clock pointed to five.

"Well, we have had an awful time," I said, as we stood in the hall together; "but at least, Clinton, the end was worth the ghastly terror.

I have knocked the bottom out of your family legend for ever."

"I don't even now quite understand," he said.

"Don't you?--but it is so easy. That coffin never contained a body at all, but was filled, as you perceive, with fragments of magnetic iron-ore. For what diabolical purposes the cell was intended, it is, of course, impossible to say; but that it must have been meant as a human trap there is little doubt. The inventor certainly exercised no small ingenuity when he devised his diabolical plot, for it was obvious that the door, which was made of iron, would swing towards the coffin wherever it happened to be placed. Thus the door would shut if the coffin were _inside the cell_, and would remain open if the coffin were _brought out_. A cleverer method for simulating a spiritual agency it would be hard to find. Of course, the monk must have known well that magnetic iron-ore never loses its quality and would ensure the deception remaining potent for ages."

"But how did you discover by means of our watches?" asked Clinton.

"Any one who understands magnetism can reply to that," I said. "It is a well-known fact that a strong magnet plays havoc with watches. The fact of both our watches going wrong first gave me a clue to the mystery."

Later in the day the whole of this strange affair was explained to Miss Curzon, and not long afterwards the pa.s.sage and entrance to the chapel were bricked up.

It is needless to add that six months later the pair were married, and, I believe, are as happy as they deserve.

THE MYSTERY OF THE FELWYN TUNNEL

I was making experiments of some interest at South Kensington, and hoped that I had perfected a small but not unimportant discovery, when, on returning home one evening in late October in the year 1893, I found a visiting card on my table. On it were inscribed the words, "Mr. Geoffrey Bainbridge." This name was quite unknown to me, so I rang the bell and inquired of my servant who the visitor had been. He described him as a gentleman who wished to see me on most urgent business, and said further that Mr. Bainbridge intended to call again later in the evening. It was with both curiosity and vexation that I awaited the return of the stranger. Urgent business with me generally meant a hurried rush to one part of the country or the other. I did not want to leave London just then; and when at half-past nine Mr. Geoffrey Bainbridge was ushered into my room, I received him with a certain coldness which he could not fail to perceive. He was a tall, well-dressed, elderly man. He immediately plunged into the object of his visit.

"I hope you do not consider my unexpected presence an intrusion, Mr.

Bell," he said. "But I have heard of you from our mutual friends, the Greys of Uplands. You may remember once doing that family a great service."

"I remember perfectly well," I answered more cordially. "Pray tell me what you want; I shall listen with attention."

"I believe you are the one man in London who can help me," he continued.

"I refer to a matter especially relating to your own particular study. I need hardly say that whatever you do will not be unrewarded."
