When, after my journey through Vologda, I returned to the capital, the Tchikhatzoff Palace was closed, and the only information the burly dvornik would vouchsafe was that the Princess had gone abroad.

I longed to penetrate the mystery surrounding her, and obtain some explanation of the extraordinary coincidence of the marks upon her wrist and mine. I had never been entirely myself since first seeing her. Some strange, occult spell seemed to enthrall me, for the phenomena I had experienced were remarkable, while the varied mental sensations were utterly mystifying.

Horribly morbid thoughts constantly oppressed me. Sometimes they were of murder, which I felt impelled to commit, even though the very suggestion was repugnant. At others, in moments of blank despair, I contemplated the easiest modes of suicide; while through all, I cherished a deadly hatred towards some person of whose identity I had not the remotest notion.

In the months that had elapsed after returning to England, I had gradually grown callous to mental anguish; yet the bodily pain I frequently experienced in the wrists and across the forehead was remarkably strange, inasmuch as livid marks would sometimes appear on my arms without any apparent cause, and disappear as suddenly as they came.

Through the hot August days I was idling in that part of Norfolk that is justly termed Poppyland, making my headquarters at a farmhouse near Cromer. I had been unusually perturbed regarding Agàfia Ivanovna, and such an intense longing to see her had seized me, that I even contemplated returning to Petersburg.

One very hot afternoon, while sitting on the bench outside the house calmly smoking, some unknown force prompted me to rise and set out for a long walk along the cliffs. I had no motive for doing this, yet a lichen-covered stile, nearly five miles in the direction of Yarmouth, was fixed in my mind as my destination, and I felt myself compelled to reach it.

The sun blazed down mercilessly, notwithstanding the cool breeze that had sprung up, and sparkling waves were breaking with sad music on the shingly beach. Engrossed in my own thoughts, I had sped on, and was just approaching the stile, when the rustle of a woman’s dress startled me, and I saw a graceful form clad in cream-coloured serge, with a bright ribbon at the waist, standing before me.

I recognised her features. It was Agàfia!

“You, Princess?” I cried in astonishment, grasping her hand.

But she uttered a low scream, and, twisting her fingers from mine, dashed swiftly away. I was unable to overtake her, for, taking a desperate leap, she alighted on a projecting rock, and, scrambling down among the bushes, descended the precipitous face of the cliff and disappeared.

Not daring to follow, I remained breathless and bewildered for about half an hour, and at length turned my heavy steps again towards Cromer.

While walking in London’s al fresco pleasure exchange, the Row, one bright spring afternoon, exchanging salutes with those I knew, a brilliantly-varnished carriage, drawn by a magnificent pair of bays, suddenly passed me. Notwithstanding the rapid pace at which it was driven, I caught a glimpse of the tip of a tiny bronze shoe stretched against the cushion of the front seat, the fold of a light fawn dress, and under a lace-fringed sunshade a fair face – the face of Agàfia Ivanovna, Princess Tchikhatzoff.

Until the equipage turned out of the Park, I kept it in sight; then I jumped into a hansom, and followed, until I watched her alight and enter one of the largest houses in Queen’s Gate. On inquiry, I ascertained that the house had been taken furnished for the season by a young foreign lady, whose name nobody seemed to know.

That evening, after dining at the club, I sat in the smoking-room, shrinking with horror from some terrible deed that I seemed forced to commit. Then gradually there crept over me that strange attraction that drew me irresistibly towards her; until at last, unable to remain, I put on my hat and drove to the house.

“I wish to see the Princess,” I said, giving my card to the grave, elderly man-servant who opened the door.

Bowing, he ushered me into a small, well-furnished room and disappeared. The moment he had gone, I heard voices speaking rapidly in Russian in the next apartment. Agàfia was addressing some man, and I thought I heard her utter my name, and refuse to see me. The rooms communicated by means of folding-doors, and, determined to speak with her, I turned the handle and entered.

The scene that met my gaze was only momentary, but it was one of tragedy. In a low lounge chair a young man was sitting, calmly smoking a cigarette. He had blonde hair, but his face was turned from me. Stealthily Agàfia crept up behind him, her face distorted by the same terrible look of vengeance that I had sometimes seen in my weird day-dreams. In her uplifted hand something gleamed in the lace-shaded lamplight. It was the knife upon which she had taken the ikon oath in Petersburg.

“Princess! At last!” I cried, rushing forward in an endeavour to prevent her from striking the deadly blow at her unsuspecting visitor.

At that moment, however, I felt my hands gripped tightly, and a man flung himself before me. With an imprecation, I tried to push him aside, for I had instantly recognised him as the man who had dined with the Princess at the Dominique.

My senses seemed paralysed. With one hand he held me, and with the thumb and finger of the other he pressed my temples so tightly that I became dazed. For a moment I was conscious of his sinister face peering into mine, and of a peal of harsh, demoniacal laughter that rang through the room. Then I knew no more.

When I recovered consciousness, I found myself lying in bed in a long hospital ward, with the kind face of my friend, Dr Ferguson, a specialist in mental diseases, looking down upon me.

I had, he told me, been found by the police early one morning lying in a back street in Kensington in a state of collapse, owing to injuries I had received on the head. For a week I had been delirious, and no hope had been entertained for my recovery; but at last I had rallied, and was now gaining strength.

He questioned me, apparently in order to ascertain if my brain had been affected; but it was remarkable that my mind was much clearer than hitherto.

It was many days before I was able to rise, but at last, when I was allowed to go out, I related to him all the circumstances surrounding the mysterious Princess.

Being much interested, he consented to accompany me to the house, and late that evening I placed my revolver in my pocket, and together we took a cab to the corner of Queen’s Gate.

Dismissing the man, we walked together to the house, only to find the shutters up and the place deserted. Our knocks and rings having been unanswered, we descended to the area, and after considerable difficulty entered by the kitchen window. By the aid of a candle we had brought with us, we searched the house, which we found still furnished, although unoccupied, and on the carpet of the room in which I had seen Agàfia was a great dark stain – the stain of blood. Was it mine, or that of the unknown victim?

Ascending to the floor above, we opened the door of the drawing-room, and on glancing round the great, handsome apartment, our eyes fell upon an object that caused us both to start back in amazement.

Attired in a long, loose gown, and chained by her wrists to one of the polished granite columns, was Agàfia!

With her hair unbound, she had sunk at the base of the pillar, and was apparently dead. Evidently she was a prisoner, for the empty jug and plate standing near told their own tale.

As in a moment of passion I bent to kiss her, Ferguson, who had placed his hand upon her breast, took out a lancet and made a slight incision in her arm.

“There is yet life,” he said.

“Thank heaven!” I cried. “We must save her.”

Opening her eyes, he took the candle and looked intently into them. They still had a fixed, stony stare, and there seemed a film upon them.

Then the doctor, with his forefinger and thumb, stroked her forehead in a downward direction, pressing her temples, saying —

“You shall now awake and feel exactly as you were before that villain placed you under his influence. Come, rouse yourself! Rouse yourself!”

Several times he repeated this, until at length her eyes twitched, her face flushed, and she gradually became perfectly conscious, answering the doctor’s questions quite rationally. But at me she glanced shyly, and blushed.

“She remembers nothing distinctly since she was hypnotised,” Ferguson said, “therefore you are a stranger.”

I endeavoured to explain that I had delivered the letter she entrusted to me; but she shook her head, saying —

“I only saw you once, in the Dominique Restaurant in Petersburg, when you drank the wine over which Petrovitch Délianoff had made passes during the few moments you were absent.”

Ferguson, who was one of the greatest English authorities on hypnotism and a student of the occult, eagerly asked what the man had done.

“He touched my forehead quickly in a curious way,” she answered, “and he afterwards dipped his finger in the wine, saying, ‘Your sensibility and soul will now leave you and be transferred to this glass of wine. In future you will feel nothing.’ Since that time I – I seem to have been in a long dream; I can remember nothing distinctly.”

“Ah! I now understand,” exclaimed my friend, raising the candle and looking into my eyes. “The man has experimented successfully upon you with the novel method of producing hypnosis recently discovered by Charcot at La Salpêtrière. Remarkable as it may seem, it is, nevertheless, possible to transfer by suggestion the sensibility of hystero-epileptic subjects to any liquid. On drinking the wine, you absorbed her sensibility, and her very soul thus transferred to you, produced the mysterious affinity of thought and deed. The very singular coincidence of the marks upon your wrists, and the curious magnetic force that impelled you towards her, are nothing more than demonstrations of the powerful psychical influence of the mind on the body.”

“What can have been the motive for all this?” I exclaimed, when, after considerable difficulty, we had broken the chains and led her to a chair.

“The motive was gold,” she answered in a weak voice. “I – I am the victim of the man Délianoff. Mine has been a tragic career. Three years ago I loved Nikanôr Baranovitch; but, although only eighteen, my mother compelled me to marry the Prince, who was nearly forty years older than myself. It is true he idolised me, but I cannot say that I experienced the least regret when, five months later, he died, leaving me all his wealth. Then, alas! my unhappiness commenced. The management of the estate was left to Délianoff, and there was a clause in the will which provided that if I died, or married Nikanôr, the property should go to Vladimir Lemontzeff, a nephew of the Prince’s who was an attaché at the Embassy in London.

“Almost as soon as the Prince was buried, Délianoff proceeded to place me under his influence, for, my mother and most of my near relations being dead, I was utterly alone. The scoundrel was an accomplished hypnotist, and in order to further his villainous scheme, he put cruel rumours in circulation which caused Petersburg society to shun me. His irresistible power of fascination I was unable to withstand, and by hypnotic suggestion he has caused me to hand over to him the greater part of my fortune. He kept me constantly in his thrall by threatening to give information to the police that I had committed murder. This crime he had suggested to me, causing me to believe that I had actually stained my hands with blood. Just at that period I saw you in the Dominique, and, as I have already explained, he practised on you one of his devilish experiments. He was a Nihilist, and on that night he used his influence to induce me to attend a meeting alone, and swear to kill whoever the Executive decided should be removed. Soon afterwards I heard of Nikanôr’s illness in Pavlova, and you were good enough to convey to him a letter in which I told him how Délianoff had attempted to cut my throat, and how utterly helpless I was in his hands.”

“Nikanôr died, and could not save you,” I observed sorrowfully.

“Yes,” she sighed; “Délianoffs motive for getting me to take the oath was as ingenious as his other villainies, for, when his plans were complete, he brought me to London, invited Vladimir here, and then, by the exercise of his occult power, he made me believe that the Prince’s nephew was the man the Executive had ordered me to kill. But you saved me, for just as I was about to strike the fatal blow, you entered. Délianoff at that moment came behind you, and, with his curious touch, insinuated in your brain the image of sleep. Of what afterwards occurred I know nothing, for I fainted.

“This scoundrel, who had planned that I should kill Vladimir and afterwards commit suicide, in order that his villainy should not be exposed, was mad with rage at the failure of his plot. When I regained consciousness, he dragged me about the room, brandishing a knife and threatening to murder me; but at last his anger cooled, and his demoniacal ingenuity devised a terrible torture. My passive will was still under his influence, and I could not escape or utter cry when he locked the fetters upon my wrists and chained me to yonder column. For several days he came regularly with food and water, but four days ago, after telling me how he had obtained possession of all that belonged to me, he laughed derisively, and said he should leave me to die of starvation.”

“Yes; we were only just in time,” the doctor remarked, feeling her pulse, with his eyes upon his watch. “You would have been dead to-morrow.”

The Princess had no friends in London, therefore I gave up my chambers to her, taking up quarters at a neighbouring hotel, while the hospital nurse I engaged attended her until she fully recovered.

She can never recover the bulk of her fortune; nevertheless she has the satisfaction of knowing that Délianoff speedily met with his deserts.

Although ostensibly a Nihilist, it was ascertained that he acted as a spy in the pay of the Secret Police. His end was befitting a coward and a traitor, for while assisting in an attempt to wreck the Winter Palace, he handled a bomb carelessly, with the result that it exploded and killed him.

Some are of opinion that, being an informer, the vengeance of the Narodnaya Volya fell upon him, and I incline to that belief.
