From behind the locked door a long-drawn cat yowl sounded fiercely. And then following it a horrible scream - and another... I recognized Lady Carmichael's voice.
"The door!" I yelled. "We must break it in. In another minute we shall be too late."
We set our shoulders against it, and heaved with all our might. It gave with a crash - and we almost fell into the room.
Lady Carmichael lay on the bed bathed in blood. I have seldom seen a more horrible sight. Her heart was still beating, but her injuries were terrible, for the skin of the throat was all ripped and torn... Shuddering, I whispered: "The Claws..." A thrill of superstitious horror ran over me.
I dressed and bandaged the wounds carefully and suggested to Settle that the exact nature of the injuries had better be kept secret, especially from Miss Patterson. I wrote out a telegram for a hospital nurse to be despatched as soon as the telegraph office was open. The dawn was now stealing in at the window. I looked out on the lawn below.
"Get dressed and come out," I said abruptly to Settle. "Lady Carmichael will be all right now."
He was soon ready, and we went out into the garden together.
"What are you going to do?"
"Dig up the cat's body," I said briefly. "I must be sure -"
I found a spade in a tool shed and we set to work beneath the large copper beech tree. At last our digging was rewarded. It was not a pleasant job. The animal had been dead a week. But I saw what I wanted to see.
"That's the cat," I said. "The identical cat I saw the first day I came here."
Settle sniffed. An odour of bitter almonds was still perceptible.
"Prussic acid," he said.
I nodded.
"What are you thinking?" he asked curiously.
"What you think, too!"
My surmise was no new one to him - it had passed through his brain also, I could see.
"It's impossible," he murmured. "Impossible! It's against all science - all nature..." His voice tailed off in a shudder. "That mouse last night," he said. "But - oh, it couldn't be!"
"Lady Carmichael," I said, "is a very strange woman. She has occult powers - hypnotic powers. Her forebears came from the East. Can we know what use she might have made of these powers over a weak lovable nature such as Arthur Carmichael's? And remember, Settle, if Arthur Carmichael remains a hopeless imbecile, devoted to her, the whole property is practically hers and her son's - whom you have told me she adores. And Arthur was going to be married!"
"But what are we going to do, Carstairs?"
"There's nothing to be done," I said. "We'll do our best, though, to stand between Lady Carmichael and vengeance."
Lady Carmichael improved slowly. Her injuries healed themselves as well as could be expected - the scars of that terrible assault she would probably bear to the end of her life.
I had never felt more helpless. The power that defeated us was still at large, undefeated, and though quiescent for the minute we could hardly regard as doing otherwise than biding its time. I was determined upon one thing. As soon as Lady Carmichael was well enough to be moved, she must be taken away from Wolden. There was just a chance that the terrible manifestation might be unable to follow her. So the days went on.
I had fixed September 18 as the date of Lady Carmichael's removal. It was on the morning of the 14th when the unexpected crisis arose.
I was in the library discussing details of Lady Carmichael's case with Settle when an agitated housemaid rushed into the room.
"Oh, sir!" she cried. "Be quick! Mr Arthur - he's fallen into the pond. He stepped on the punt and it pushed off with him, and he overbalanced and fell in! I saw it from the window."
I waited for no more, but ran straight out of the room followed by Settle. Phyllis was just outside and had heard the maid's story. She ran with us.
"But you needn't be afraid," she cried. "Arthur is a magnificent swimmer."
I felt forebodings, however, and redoubled my pace. The surface of the pond was unruffled. The empty punt floated lazily about - but of Arthur there was no sign.
Settle pulled off his coat and his boots. "I'm going in," he said. "You take the boat hook and fish about from the other punt. It's not very deep."
Very long the time seemed as we searched vainly.
Minute followed minute. And then, just as we were despairing, we found him, and bore the apparently lifeless body of Arthur Carmichael to shore.
As long as I live I shall never forget the hopeless agony of Phyllis's face.
"Not - not -" Her lips refused to frame the dreadful word.
"No, no, my dear," I cried. "We'll bring him round, never fear."
But inwardly I had little hope. He had been under water for half an hour. I sent off Settle to the house for hot blankets and other necessaries, and began myself to apply artificial respiration.
We worked vigorously with him for over an hour, but there was no sign of life. I motioned to Settle to take my place again, and I approached Phyllis.
"I'm afraid," I said gently, "that it is no good. Arthur is beyond our help."
