There was something in her form that struck me as curious, and as she slowly raised the knife to her lips, and kissed the thin, double-edged blade, I rushed across and looked into her face.

It was the woman I had noticed in the Dominique! She had taken an oath to commit murder at the bidding of the Revolutionists! There was the same fixed look in her eyes, the same blank, expressionless countenance, and as she turned and faced the council of desperate conspirators, her teeth were firmly set and her bejewelled hands tightly-clenched.

As her eyes met mine, I fancied she started, but the words of the president attracted her attention.

“It is enough,” he said solemnly. “To-morrow you will receive instructions. You have joined us, therefore never forget that the punishment inflicted on those who divulge our secret is always swift and decisive—death!”

A shudder ran through her, the knife fell from her grasp, and she reeled and would have fallen, had not an elderly, grey-haired woman jumped up from her seat and caught her.

In a few moments, however, she recovered, and the pair walked slowly out.

When they had left, I inquired the name of the mysterious stranger, but all information was refused. Secrecy is one of the chief tenets of the Nihilistic creed, and frequently members of the same Circle do not know one another. The Terrorist organisations are most elaborate and far-reaching, and the more I have known of their operations, the more wonderful they have always seemed. The business of the Executive with me was unimportant—merely to give me some information which I might send to London, and which, when published in my journal, would be calculated to take the police off the scent of a fugitive conspirator who was being diligently sought for by the ubiquitous members of the Third Section of the Ministry of the Interior.

When I left, half an hour later, I went straight to my bachelor lodgings in a tall and rather gloomy house on the other side of the Moika. Lighting a cigarette, and drawing my armchair close to the stove, I sat for a long time in my dimly-lighted sitting-room, pondering over the events of the evening. How long I sat there I have no idea, but I was aroused by distinctly hearing a woman’s shrill scream. At the same time, I felt a tight pressure on my right wrist, as if it were being held by bony fingers, and on my throat I felt a strange, cold sensation, as if a knife had been drawn across it.

Again I was mystified on discovering that I was alone; that it was nothing but a weird sensation! Yet, on removing the green shade from my reading-lamp, and going over to the mirror, I saw upon my throat a thin red line, while upon my wrist were three red marks that had apparently been left by unseen fingers!

During the weeks that followed, I seemed filled with a terrible dread of some utterly vague danger, and before my eyes came frequent visions of the pale, handsome face of the beautiful woman who had allied herself with the most dangerous group of the Narodnaya Volya. Was there, I wondered, some mysterious affinity between us? So puzzled was I to account for the strange phenomena, and the fact that the curious marks upon my wrist still remained, that I began to fear that the periodical fits of passion and despair were precursory of madness.
