At the risk of incurring the suspicions of the police agent stationed in the hotel, I mingled some hot water in the bath which I took on the first morning after my arrival. Then, having made my toilet and eaten the heavy breakfast provided for English visitors, I set out, suffering sadly from indigestion, to present my letter of introduction to the Princess.

As this woman, the most brilliant recruit ever received into the Russian secret service, and a foe of whom I am not ashamed to confess that I felt some fear, has never been heard of by the public of Great Britain, I shall say a word concerning her.

The Princess, whose Christian name was Sophia, was the daughter of a boyar of Little Russia. Her extraordinary beauty, while she was still a very young girl, attracted the attention of the governor of the province, Prince Y——, who was one of the wealthiest nobles in the Empire, and a widower. He made proposals for her hand which were accepted by her father, without the girl herself being asked to express an opinion in the matter, and at the age when an English girl would be leaving home for a convent or “high-school,” Sophia became the Governor’s wife.

Almost immediately the Prince resigned his government and went to live in his splendid palace on the Nevsky Prospect, in Petersburg. Before very long, society in the Russian capital was startled to hear of the sudden deaths in rapid succession of both the Prince’s children by his former wife, a son and a daughter. Then, after a brief interval, followed the tragic death of the Prince himself, who was found in bed one morning by his valet, with his throat cut.

The almost satanic beauty and fascination of the youthful Princess had made her from the very first one of the most conspicuous personages at the Imperial Court. These three deaths, following on the heels of one another, roused the most dreadful suspicions, and the Czar Alexander III. personally charged his minister of justice to see that the law was carried out.

Accordingly the police took possession of the palace while the corpse of its late owner still lay where it had been found. The most searching investigations were made, the servants were questioned and threatened, and it was rumored that the widow herself was for a short time under arrest.

Suddenly a great change took place. The police withdrew, professing themselves satisfied that no crime had been committed. The deaths of the son and daughter were put down to natural causes, and that of the Prince was pronounced a suicide, due to grief at the loss of his children. Some of the servants disappeared—it was said into Siberia—and in due course the Princess resumed her place in society and at Court, as though nothing were amiss.

Nevertheless, from that hour, as I have every reason to know, her life was really that of a slave to the head of the secret police. She appeared to go about unfettered, and to revel in the enjoyment of every luxury; but her time, her actions, and the vast wealth bequeathed to her by her husband, were all at the disposal of her tyrant.

Time after time, in half the capitals of Europe, but more especially, of course, in that of Russia, I had come on traces of this terrible woman, not less terrible if it were true that she was herself the most miserable victim of the system of which she formed part.
