1“You are right. My real name is Harry Lucas. My father was a retired soldier who came out to farm in Rhodesia. He died when I was in my second year at Cambridge.”

2“Were you fond of him?” I asked suddenly.

3“I—don’t know.”

4Then he flushed and went on with sudden vehemence:

5“Why do I say that? I did love my father. We said bitter things to each other the last time I saw him, and we had many rows over my wildness and my debts, but I cared for the old man. I know how much now—when it’s too late,” he continued more quietly. “It was at Cambridge that I met the other fellow——”

6“Young Eardsley?”

7“Yes—young Eardsley. His father, as you know, was one of South Africa’s most prominent men. We drifted together at once, my friend and I. We had our love of South Africa in common and we both had a taste for the untrodden places of the world. After he left Cambridge, Eardsley had a final quarrel with his father. The old man had paid his debts twice, he refused to do so again. There was a bitter scene between them. Sir Laurence declared himself at the end of his patience—he would do no more for his son. He must stand on his own legs for a while. The result was, as you know, that those two young men went off to South America together, prospecting for diamonds. I’m not going into that now, but we had a wonderful time out there. Hardships in plenty, you understand, but it was a good life—a hand-to-mouth scramble for existence far from the beaten track—and, my God! that’s the place to know a friend. There was a bond forged between us two out there that only death could have broken. Well, as Colonel Race told you, our efforts were crowned with success. We found a second Kimberley in the heart of the British Guiana jungles. I can’t tell you our elation. It wasn’t so much the actual value in money of the find—you see, Eardsley was used to money, and he knew that when his father died he would be a millionaire, and Lucas had always been poor and was used to it. No, it was the sheer delight of discovery.”

8He paused, and then added, almost apologetically:

9“You don’t mind my telling it this way, do you? As though I wasn’t in it at all. It seems like that now when I look back and see those two boys. I almost forget that one of them was—Harry Rayburn.”

10“Tell it any way you like,” I said, and he went on:

11“We came to Kimberley—very cock-a-hoop over our find. We brought a magnificent selection of diamonds with us to submit to the experts. And then—in the hotel at Kimberley—we met her——”

12I stiffened a little, and the hand that rested on the doorpost clenched itself involuntarily.

13“Anita Grünberg—that was her name. She was an actress. Quite young and very beautiful. She was South African born, but her mother was a Hungarian, I believe. There was some sort of mystery about her, and that, of course, heightened her attraction for two boys home from the wilds. She must have had an easy task. We both fell for her right away, and we both took it hard. It was the first shadow that had ever come between us—but even then it didn’t weaken our friendship. Each of us, I honestly believe, was willing to stand aside for the other to go in and win. But that wasn’t her game. Sometimes, afterwards, I wondered why it hadn’t been, for Sir Laurence Eardsley’s only son was quite a parti. But the truth of it was that she was married—to a sorter in De Beers’—though nobody knew of it. She pretended enormous interests in our discovery, and we told her all about it and even showed her the diamonds. Delilah—that’s what she should have been called—and she played her part well!

14“The De Beers robbery was discovered, and like a thunderclap the police came down upon us. They seized our diamonds. We only laughed at first—the whole thing was so absurd. And then the diamonds were produced in court—and without question they were the stones stolen from De Beers’. Anita Grünberg had disappeared. She had effected the substitution neatly enough, and our story that these were not the stones originally in our possession was laughed to scorn.

15“Sir Laurence Eardsley had enormous influence. He succeeded in getting the case dismissed—but it left two young men ruined and disgraced to face the world with the stigma of thief attached to their names, and it pretty well broke the old fellow’s heart. He had one bitter interview with his son in which he heaped upon him every reproach imaginable. He had done what he could to save the family name, but from that day on his son was his son no longer. He cast him off utterly. And the boy, like the proud young fool that he was, remained silent, disdaining to protest his innocence in the face of his father’s disbelief. He came out furious from the interview—his friend was waiting for him. A week later war was declared. The two friends enlisted together. You know what happened. The best pal a man ever had was killed, partly through his own mad recklessness in rushing into unnecessary danger. He died with his name tarnished. . . .

16“I swear to you, Anne, that it was mainly on his account that I was so bitter against that woman. It had gone deeper with him than with me. I had been madly in love with her for the moment—I even think that I frightened her sometimes—but with him it was a quieter and deeper feeling. She had been the very centre of his universe—and her betrayal of him tore up the very roots of life. The blow stunned him and left him paralyzed.”

17Harry paused. After a minute or two he went on:

18“As you know, I was reported ‘Missing, presumed killed.’ I never troubled to correct the mistake. I took the name of Parker and came to this island, which I knew of old. At the beginning of the war, I had had ambitious hopes of proving my innocence, but now all that spirit seemed dead. All I felt was, ‘What’s the good?’ My pal was dead, neither he nor I had any living relations who would care. I was supposed to be dead too, let it remain at that. I led a peaceful existence here, neither happy nor unhappy—numbed of all feeling. I see now, though I did not realize it at the time, that that was partly the effect of the war.

19“And then one day something occurred to wake me right up again. I was taking a party of people in my boat on a trip up the river, and I was standing at the landing-stage, helping them in, when one of the men uttered a startled exclamation. It focused my attention on him. He was a small, thin man with a beard, and he was staring at me for all he was worth as though I was a ghost. So powerful was his emotion that it awakened my curiosity. I made inquiries about him at the hotel and learned that his name was Carton, that he came from Kimberley, and that he was a diamond-sorter employed by De Beers’. In a minute all the old sense of wrong surged over me again. I left the island and went to Kimberley.

20“I could find out little more about him, however. In the end, I decided that I must force an interview. I took my revolver with me. In the brief glimpse I had had of him, I had realized that he was a physical coward. No sooner were we face to face than I recognized that he was afraid of me. I soon forced him to tell me all he knew. He had engineered part of the robbery and Anita Grünberg was his wife. He had once caught sight of both of us when we were dining with her at the hotel, and, having read that I was killed, my appearance in the flesh at the Falls had startled him badly. He and Anita had married quite young, but she had soon drifted away from him. She had got in with a bad lot, he told me—and it was then for the first time that I heard of the ‘Colonel.’ Carton himself had never been mixed up in anything except this one affair—so he solemnly assured me, and I was inclined to believe him. He was emphatically not of the stuff of which successful criminals are made.

21“I still had the feeling that he was keeping back something. As a test, I threatened to shoot him there and then, declaring that I cared very little what became of me now. In a frenzy of terror he poured out a further story. It seems that Anita Grünberg did not quite trust the ‘Colonel.’ Whilst pretending to hand over to him the stones she had taken from the hotel, she kept back some in her own possession. Carton advised her, with his technical knowledge, which to keep. If, at any time, these stones were produced, they were of such colour and quality as to be readily identifiable, and the experts at De Beers’ would admit at once that these stones had never passed through their hands. In this way my story of a substitution would be supported, my name would be cleared, and suspicion would be diverted to the proper quarter. I gathered that, contrary to his usual practice, the ‘Colonel’ himself had been concerned in this affair, therefore Anita felt satisfied that she had a real hold over him, should she need it. Carton now proposed that I should make a bargain with Anita Grünberg, or Nadina, as she now called herself. For a sufficient sum of money he thought that she would be willing to give up the diamonds and betray her former employer. He would cable to her immediately.

22“I was still suspicious of Carton. He was a man whom it was easy enough to frighten, but who, in his fright, would tell so many lies that to sift the truth out from them would be no easy job. I went back to the hotel and waited. By the following evening I judged that he would have received the reply to his cable. I called round at his house and was told that Mr. Carton was away, but would be returning on the morrow. Instantly I became suspicious. In the nick of time I found out that he was in reality sailing for England on the Kilmorden Castle, which left Cape Town in two days’ time. I had just time to journey down and catch the same boat.

23“I had no intention of alarming Carton by revealing my presence on board. I had done a good deal of acting in my time at Cambridge, and it was comparatively easy for me to transform myself into a grave bearded gentleman of middle age. I avoided Carton carefully on board the boat, keeping to my own cabin as far as possible under the pretence of illness.

24“I had no difficulty in trailing him when we got to London. He went straight to an hotel and did not go out until the following day. He left the hotel shortly before one o’clock. I was behind him. He went straight to a house-agent in Knightsbridge. There he asked for particulars of houses to let on the river.

25“I was at the next table also inquiring about houses. Then suddenly in walked Anita Grünberg, Nadina—whatever you like to call her. Superb, insolent, and almost as beautiful as ever. God! how I hated her. There she was, the woman who had ruined my life—and who had also ruined a better life than mine. At that minute I could have put my hands round her neck and squeezed the life out of her inch by inch! Just for a minute or two I saw red. I hardly took in what the agent was saying. It was her voice that I heard next, high and clear, with an exaggerated foreign accent: ‘The Mill House, Marlow. The property of Sir Eustace Pedler. That sounds as though it might suit me. At any rate, I will go and see it.’

26“The man wrote her an order, and she walked out again in her regal insolent manner. Not by word or a sign had she recognized Carton, yet I was sure that their meeting there was a preconceived plan. Then I started to jump to conclusions. Not knowing that Sir Eustace was at Cannes, I thought that this house-hunting business was a mere pretext for meeting him in the Mill House. I knew that he had been in South Africa at the time of the robbery, and never having seen him I immediately leaped to the conclusion that he himself was the mysterious ‘Colonel’ of whom I had heard so much.

27“I followed my two suspects along Knightsbridge. Nadina went into the Hyde Park Hotel. I quickened my pace and went in also. She walked straight into the restaurant, and I decided that I would not risk her recognizing me at the moment, but would continue to follow Carton. I was in great hopes that he was going to get the diamonds, and that by suddenly appearing and making myself known to him when he least expected it I might startle the truth out of him. I followed him down into the Tube station at Hyde Park Corner. He was standing by himself at the end of the platform. There was some girl standing near, but no one else. I decided that I would accost him then and there. You know what happened. In the sudden shock of seeing a man whom he imagined far away in South Africa, he lost his head and stepped back upon the line. He was always a coward. Under the pretext of being a doctor, I managed to search his pockets. There was a wallet with some notes in it and one or two unimportant letters, there was a roll of films—which I must have dropped somewhere later—and there was a piece of paper with an appointment made on it for the 22nd on the Kilmorden Castle. In my haste to get away before any one detained me, I dropped that also, but fortunately I remembered the figures.

28“I hurried to the nearest cloak-room and hastily removed my make-up. I did not want to be laid by the heels for picking a dead man’s pocket. Then I retraced my steps to the Hyde Park Hotel. Nadina was still having lunch. I needn’t describe in detail how I followed her down to Marlow. She went into the house, and I spoke to the woman at the lodge, pretending that I was with her. Then I, too, went in.”

29He stopped. There was a tense silence.

30“You will believe me, Anne, won’t you? I swear before God that what I am going to say is true. I went into the house after her with something very like murder in my heart—and she was dead! I found her in that first-floor room—God! It was horrible. Dead—and I was not more than three minutes behind her. And there was no sign of any one else in the house! Of course I realized at once the terrible position I was in. By one master-stroke the blackmailed had rid himself of the blackmailer, and at the same time had provided a victim to whom the crime would be ascribed. The hand of the ‘Colonel’ was very plain. For the second time I was to be his victim. Fool that I had been to walk into the trap so easily.

31“I hardly know what I did next. I managed to go out of the place looking fairly normal, but I knew that it could not be long before the crime was discovered and a description of my appearance telegraphed all over the country.

32“I lay low for some days, not daring to make a move. In the end chance came to my aid. I overheard a conversation between two middle-aged gentlemen in the street, one of whom proved to be Sir Eustace Pedler. I at once conceived the idea of attaching myself to him as his secretary. The fragment of conversation I had overheard gave me my clue. I was now no longer so sure that Sir Eustace Pedler was the ‘Colonel.’ His house might have been appointed as a rendezvous by accident, or for some obscure motive that I had not fathomed.”

33“Do you know,” I interrupted, “that Guy Pagett was in Marlow at the date of the murder?”

34“That settles it then. I thought he was at Cannes with Sir Eustace.”

35“He was supposed to be in Florence—but he certainly never went there. I’m pretty certain he was really in Marlow, but of course I can’t prove it.”

36“And to think I never suspected Pagett for a minute until the night he tried to throw you overboard. The man’s a marvellous actor.”

37“Yes, isn’t he?”

38“That explains why the Mill House was chosen. Pagett could probably get in and out of it unobserved. Of course he made no objection to my accompanying Sir Eustace across in the boat. He didn’t want me laid by the heels immediately. You see, evidently Nadina didn’t bring the jewels with her to the rendezvous as they had counted on her doing. I fancy that Carton really had them and concealed them somewhere on the Kilmorden Castle—that’s where he came in. They hoped that I might have some clue as to where they were hidden. As long as the ‘Colonel’ did not recover the diamonds, he was still in danger—hence his anxiety to get them at all costs. Where the devil Carton hid them—if he did hide them, I don’t know.”

39“That’s another story,” I quoted. “My story. And I’m going to tell it you now.”
