"The liar!" I cried.

"He told me many things which naturally excited me, and which, loving you as I did, drove me to madness. I refused at first to heed his words, for somehow I mistrusted him--I know not why! But he offered to give me proof. If I went that night, or early in the morning, to Harrington Gardens, I would find her there, and I might question her. Imagine my state of mind after what he had revealed to me. I promised I would come there in secret, and I went home, my mind full of the lies and suspicion which he had, I now see, so cleverly suggested. I didn't then know him to be an a.s.sa.s.sin, but, mistrusting him as I did, I took for my own protection the old knife from the table in the drawing-room, and concealed it inside my blouse. At one o'clock next morning I crept out of the house noiselessly, and walked to Harrington Gardens, where I opened the outer door with the latch-key he had given me. On ascending to his flat I heard voices--I heard your voice, dear--therefore I descended into the dark and waited--waited until you came down the stairs and left. I saw you, and I was mad--mad! Then I went up, and he admitted me. The trap was already laid for me. I crossed that threshold to my doom!"

"How?" I asked in my despair. "Tell me all, Phrida,--everything!"

But at this point the Peruvian, Senos, interrupted, saying:

"Let me speak, sare. I tell you," he cried quickly.

"When I speak to the lady in Pall Mall I follow her. She go that afternoon to Harrington Gardens, but there see Mrs. Petre, whom she already know. Mrs. Petre find her excited, and after questioning her, induce her to tell her what I say--that Cane he kill my master. Then Mrs.

Petre say, Sir Digby away in the country--not return to London--at Paddington--till one o'clock in the morning. I listen to it all, for Senos friend of the hall-porter--eh? So young laidee she says she come late in the night--half-past one or two o'clock--and ask himself the truth. But Cane in his room all the time, of course."

"Well, Phrida?" I asked quickly. "Tell us what happened on that night when you entered."

"Yes," cried Cane sarcastically, "Lie to them--they'll believe you, of course!"

"When I entered that man took me into the sitting-room, and I sat down.

Naturally I was very upset. Mrs. Petre, whom I had met before, was there, and after he had told me many things about your relations with the daughter of a hair-dresser--things which maddened me--Mrs. Petre admitted her from the adjoining room. I was mad with jealousy, loving you as I did. What happened between us I do not know. I--I only fear that--that I took the knife from my breast and, in a frenzy of madness--killed her!"

And she covered her face with her hands.

"Exactly!" cried Cane. "I'm glad you have the moral courage to admit it."

"But describe exactly what occurred--as far as you know," Edwards said, pressing her.

"I know that I was in a frenzy of pa.s.sion, and hysterical, perhaps," she said at last. "I recollect Mrs. Petre saying that I looked very unwell, and fetching me some smelling-salts from the next room. I smelt them, but the odour was faint and strange, and a few moments later I--well, I knew no more."

"And then--afterwards?" I asked very gravely.

"When, later on I came to my senses," she said in slow, hard tones, as though reflecting, "I found the girl whom I believed to be my rival in your affections lying on the ground. In her breast was the knife. Ah, shall I ever forget that moment when I realised what I had done! Cane was bending over me, urging me to remain calm. He told me that my rival was dead--that I had killed her and that she would not further interfere with my future. I--I saw him bend over the body, withdraw the knife, and wipe it upon his handkerchief, while that woman, his accomplice, looked on.

Then he gave me back the knife, which instinctively I concealed, and bade me go quickly and noiselessly back home, promising secrecy, and declaring that both he and Mrs. Petre would say nothing--that my terrible secret was safe in their hands. I believed them, and I crept down the stairs out into the road, and walked home to Cromwell Road. I replaced the knife in the drawing-room, and I believed them until--until I knew that you guessed my secret! Then came that woman's betrayal, and I knew that my doom was sealed," she added, her chin sinking upon her breast.

"You see," laughed Cane defiantly, "that the girl admits her guilt. She was jealous of Marie Bracq, and in a frenzy of pa.s.sion struck her down.

Mrs. Petre was there and witnessed it. She will describe it all to you, no doubt, when she recovers."

"And what she will say is one big lie," declared Senos, coming forward again. "We all know Mrs. Petre," he laughed in his high-pitched voice; "she is your tool--she and Luis. But he become a snake-charmer and give exhibitions at music-halls. He bit by one snake at Darlington, a month ago, and die quick. Ah, yes! Senos know! Snake bite him, because he brought snake and give him to that man to bite my poor master."

"Why will Mrs. Petre tell lies, Senos?" demanded Edwards who, with Fremy, was listening with the greatest interest and putting the threads of the tangled skein together in their proper sequence.

"Because I, Senos, was at Harrington Gardens that night. I knew that the laidee I had spoken to was going there, and I feared that some-ting might happen, for Cane a desperate man when charged with the truth."

"You were there!" I gasped. "What do you know?"

"Well, this," said the narrow-eyed man who had hunted down the a.s.sa.s.sin of his master. "I waited outside the house--waited some hours--when about eleven Cane he came down and unfastened the door and leave it a little open. I creep in, and soon after you, Mr. Royle, you come in. I wait and see you go upstairs. Then I creep up and get out of the window on the landing and on to the roof, where I see inside Cane's room--see all that goes on. My friend, the hall-porter, he tell me this sometime before, and I find the spot where, kneeling down, I see between the blinds. I see you talk with him and I see you go. Then I see Miss Shand--she come in and Mrs. Petre, and Cane talk to her. She very excited when she meet young laidee, and Mrs. Petre she give her bottle to smell. Then she faint off.

The laidee, daughter of great Duke, she say something to Cane. He furious. She repeat what I say to her. Then Mrs. Petre, who had given Miss Shand the smelling-salts, find knife in her breast and secretly puts it into Cane's hand. In a moment Cane strikes the young lady with it--ah!

full in the chest--and she sinks on the floor--dead! It went into her heart. Cane and the woman Petre talk in low whispers for few minutes, both very afraid. Then Miss Shand she wakes, opens her eyes, and sees the young laidee dead on the floor. She scream, but Mrs. Petre puts her hand over her mouth. Cane take out the knife, wipe it, and after telling her something, Miss Shand creep away. Oh, yes, Senos he see it all! Miss Shand quite innocent--she do nothing. Cane kill daughter of the great Duke--he with his own hand--he kill her. Senos saw him--with his own eyes!"

"Ah!" I cried, rushing towards the native, and gripping both his brown hands. "Thank you, Senos, for those words. You have saved the woman I love, for you are an eye-witness to that man's crime which with such subtle ingenuity he has endeavoured to fasten upon her, and would have succeeded had it not been for your dogged perseverance and astuteness."

"He kill my master," replied the Peruvian simply. "I watch him and convict him. He bad a.s.sa.s.sin, gentlemens--very bad man!"

CHAPTER x.x.xII.

IS THE CONCLUSION.

"Do you really believe that man?" asked Cane, turning to us quite coolly, a sarcastic smile upon his lips.

He was a marvellous actor, for he now betrayed not the slightest confusion. He even laughed at the allegations made against him. His bold defiance utterly amazed us. Yet we knew now how resourceful and how utterly unscrupulous he was.

"Yes, I do!" was the officer's reply. "You murdered her Highness, fearing that she should go to her father and expose you before you could have time to dispose of your stolen concession to him. Had she gone to him, the police would hunt you down as Sir Digby's a.s.sa.s.sin. But by closing her lips you hoped to be able to sell back the concession and still preserve your guilty secret."

"Of course," remarked Fremy, "the whole affair is now quite plain. Poor Miss Shand was drawn into the net in order to become this scoundrel's victim. He intended from the first to make use of her in some way, and did so at last by making her believe she had killed her alleged rival in Mr. Royle's affection. Truly this man is a clever and unscrupulous scoundrel, for he succeeded in obtaining a quarter of a million francs from a reigning sovereign for a doc.u.ment, to obtain which he had committed a foul and dastardly crime!"

"A lie--lies, all of it!" shouted the accused angrily, his face as white as paper.

"Oh, do not trouble," laughed Fremy, speaking in French. "You will have an opportunity to make your defence before the judge--you and your ingenious accomplice, Mrs. Petre."

"We want her in England for the attempted murder of Mr. Royle," Edwards remarked. "I'll apply for her extradition to-morrow. Your chief will, no doubt, decide to keep Cane here--at least, for the present. We shall want him for the murder of the Englishman, Sir Digby Kemsley."

"You may want me," laughed the culprit with an air of supreme defiance, "but you'll never have me! Oh, no, no! I'll remain over here, and leave you wanting me."

"Prisoner, what is the use of these denials and this defiance?" asked Fremy severely in French, advancing towards him. "You are in my custody--and under the law of the Kingdom of Belgium I arrest you for the murder of Sir Digby Kemsley, in Peru, and for the murder of Stephanie, daughter of his Highness the Grand Duke of Luxemburg." Then, turning to his two subordinates, he added briefly: "Put the handcuffs on him! He may give trouble!"

"Handcuffs! Ha, ha!" cried Senos the Peruvian, laughing and snapping his brown fingers in the prisoner's face. "It is my triumph now. Senos has avenged the death of his poor, good master!"

"A moment," exclaimed the prisoner. "I may at least be permitted to secure my papers before I leave here, and hand them over to you? They will, perhaps, interest you," he said quite coolly. Then he took from his watch-chain a small key, and with it opened a little cupboard in the wall, from whence he took a small, square deed-box of j.a.panned tin, which he placed upon the table before us.

With another and smaller key, and with a slight grin upon his face, he opened the lid, but a cry of dismay escaped us, for next second we saw that he held in his hand a small, black object, sinuous and writhing--a small, thin, but highly venomous black snake!

It was over in an instant, ere we could realise the truth. Upon his white wrist I saw a tiny bead of blood, where the reptile had struck and bitten him, and as he flung it back into the box and banged down the lid he turned upon us in defiance, and said:

"Now take me! I am ready," he cried, uttering a peal of fiendish laughter. "Carry me where you will, for in a few moments I shall be dead.

Ah! yes, my good friends! I have played the great game--and lost. Yet I've cheated you all, as I always declared that I would."

The two men sprang forward to slip the metal gyves upon his wrists, but Fremy, noticing the instant change in the a.s.sa.s.sin's countenance, motioned them off.

The culprit's face grew ashen grey, his thin jaws were fixed. He tried to utter some further words, but no sound came from him, only a low gurgle.

We stood by and watched. He placed both his palms to his brow and stood for a few seconds in the centre of the room. Then a paroxysm of pain seemed to double him completely up, and he fell to the carpet writhing in most fearful agony. It was horrible to witness, and Phrida, with a cry, turned away.

Then suddenly he lay stiff, and stretched his limbs to such an extent that we could hear the bones crack. His back became arched, and then he expired with horrible convulsions, which held his limbs stiffened and extended to their utmost limits--truly, the most awful and agonising of deaths, and a torture in the last moments that must have been excruciating--a punishment worse, indeed, than any that man-made law might allow.

As Herbert Cane paid the penalty of his crimes the woman Petre at last recovered consciousness.
