“Once he was out of sight I went to the house adopting all the style and all the mannerisms of poor Gathercole. My beginning was unfortunate for, with a shock, I recognised in the valet a fellow-convict who had been with me in the warder’s cottage on the morning of my escape from Dartmoor. There was no mistaking him, and when I heard his voice I was certain. Would he recognise me I wondered, in spite of my beard and my eyeglasses?
“Apparently he did not. I gave him every chance. I thrust my face into his and on my second visit challenged him, in the eccentric way which poor old Gathercole had, to test the grey of my beard. For the moment however, I was satisfied with my brief experiment and after a reasonable interval I went away, returning to my place off Victoria Street and waiting till the evening.
“In my observation of the house, whilst I was waiting for Kara to depart, I had noticed that there were two distinct telephone wires running down to the roof. I guessed, rather than knew, that one of these telephones was a private wire and, knowing something of Kara’s fear, I presumed that that wire would lead to a police office, or at any rate to a guardian of some kind or other. Kara had the same arrangement in Albania, connecting the palazzo with the gendarme posts at Alesso. This much Hussein told me.
“That night I made a reconnaissance of the house and saw Kara’s window was lit and at ten minutes past ten I rang the bell and I think it was then that I applied the test of the beard. Kara was in his room, the valet told me, and led the way upstairs. I had come prepared to deal with this valet for I had an especial reason for wishing that he should not be interrogated by the police. On a plain card I had written the number he bore in Dartmoor and had added the words, ‘I know you, get out of here quick.’
“As he turned to lead the way upstairs I flung the envelope containing the card on the table in the hall. In an inside pocket, as near to my body as I could put them, I had the two candles. How I should use them both I had already decided. The valet ushered me into Kara’s room and once more I stood in the presence of the man who had killed my girl and blotted out all that was beautiful in life for me.”
There was a breathless silence when he paused. T.X. leaned back in his chair, his head upon his breast, his arms folded, his eyes watching the other intently.
The Chief Commissioner, with a heavy frown and pursed lips, sat stroking his moustache and looking under his shaggy eyebrows at the speaker. The French police officer, his hands thrust deep in his pockets, his head on one side, was taking in every word eagerly. The sallow-faced Russian, impassive of face, might have been a carved ivory mask. O’Grady, the American, the stump of a dead cigar between his teeth, shifted impatiently with every pause as though he would hurry forward the denouement.
Presently John Lexman went on.
“He slipped from the bed and came across to meet me as I closed the door behind me.
“‘Ah, Mr. Gathercole,’ he said, in that silky tone of his, and held out his hand.
“I did not speak. I just looked at him with a sort of fierce joy in my heart the like of which I had never before experienced.
“‘And then he saw in my eyes the truth and half reached for the telephone.
“But at that moment I was on him. He was a child in my hands. All the bitter anguish he had brought upon me, all the hardships of starved days and freezing nights had strengthened and hardened me. I had come back to London disguised with a false arm and this I shook free. It was merely a gauntlet of thin wood which I had had made for me in Paris.
“I flung him back on the bed and half knelt, half laid on him.
“‘Kara,’ I said, ‘you are going to die, a more merciful death than my wife died.’
“He tried to speak. His soft hands gesticulated wildly, but I was half lying on one arm and held the other.
“I whispered in his ear:
“‘Nobody will know who killed you, Kara, think of that! I shall go scot free — and you will be the centre of a fine mystery! All your letters will be read, all your life will be examined and the world will know you for what you are!’
“I released his arm for just as long as it took to draw my knife and strike. I think he died instantly,” John Lexman said simply.
“I left him where he was and went to the door. I had not much time to spare. I took the candles from my pocket. They were already ductile from the heat of my body.
“I lifted up the steel latch of the door and propped up the latch with the smaller of the two candles, one end of which was on the middle socket and the other beneath the latch. The heat of the room I knew would still further soften the candle and let the latch down in a short time.
“I was prepared for the telephone by his bedside though I did not know to whither it led. The presence of the paperknife decided me. I balanced it across the silver cigarette box so that one end came under the telephone receiver; under the other end I put the second candle which I had to cut to fit. On top of the paperknife at the candle end I balanced the only two books I could find in the room, and fortunately they were heavy.
“I had no means of knowing how long it would take to melt the candle to a state of flexion which would allow the full weight of the books to bear upon the candle end of the paperknife and fling off the receiver. I was hoping that Fisher had taken my warning and had gone. When I opened the door softly, I heard his footsteps in the hall below. There was nothing to do but to finish the play.
“I turned and addressed an imaginary conversation to Kara. It was horrible, but there was something about it which aroused in me a curious sense of humour and I wanted to laugh and laugh and laugh!
“I heard the man coming up the stairs and closed the door gingerly. What length of time would it take for the candle to bend!
“To completely establish the alibi I determined to hold Fisher in conversation and this was all the easier since apparently he had not seen the envelope I had left on the table downstairs. I had not long to wait for suddenly with a crash I heard the steel latch fall in its place. Under the effect of the heat the candle had bent sooner than I had expected. I asked Fisher what was the meaning of the sound and he explained. I passed down the stairs talking all the time. I found a cab at Sloane Square and drove to my lodgings. Underneath my overcoat I was partly dressed in evening kit.
“Ten minutes after I entered the door of my flat I came out a beardless man about town, not to be distinguished from the thousand others who would be found that night walking the promenade of any of the great music-halls. From Victoria Street I drove straight to Scotland Yard. It was no more than a coincidence that whilst I should have been speaking with you all, the second candle should have bent and the alarm be given in the very office in which I was sitting.
“I assure you all in all earnestness that I did not suspect the cause of that ringing until Mr. Mansus spoke.
“There, gentlemen, is my story!” He threw out his arms.
“You may do with me as you will. Kara was a murderer, dyed a hundred times in innocent blood. I have done all that I set myself to do — that and no more — that and no less. I had thought to go away to America, but the nearer the day of my departure approached, the more vivid became the memory of the plans which she and I had formed, my girl… my poor martyred girl!”
He sat at the little table, his hands clasped before him, his face lined and white.
“And that is the end!” he said suddenly, with a wry smile.
“Not quite!” T.X. swung round with a gasp. It was Belinda Mary who spoke.
“I can carry it on,” she said.
She was wonderfully self-possessed, thought T.X., but then T.X. never thought anything
