"I can't get out! The stone has sunk into its place! We are locked in!" he screamed, and, wild with fear, he plunged headlong into the cell, upsetting me in his career before I could check him. I sprang back to the door as it was closing. I was too late. Before I could reach it, it had shut with a loud clang in obedience to the infernal witchcraft.
"You have done it now," I cried angrily. "Do you see? Why, man, we are buried alive in this ghastly hole!"
The lantern I had placed just inside the door, and by its dim light, as I looked at him, I saw the terror of a madman creep into Clinton's eyes.
"Buried alive!" he shouted, with a peal of hysterical laughter. "Yes, and, Bell, it's your doing; you are a devil in human shape!" With a wild paroxysm of fury he flung himself upon me. There was the ferocity of a wild beast in his spring. He upset the lantern and left us in total darkness.
The struggle was short. We might be buried alive, but I was not going to die by his hand, and seizing him by the throat I pinned him against the wall.
"Keep quiet," I shouted. "It is your thundering stupidity that has caused all this. Stay where you are until I strike a match."
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 God! 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 masses. 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 mass, 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 passage?"
"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 passage 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."
