"Samarova," he said at length to us, "was arrested for her part in the assassination of Grand Duke Sergius and thrown into solitary confinement in the fortress of St. Peter and St. Paul. They tortured her, the beasts - burned her body with their cigarettes. It was unspeakable. But she would not confess, and finally they had to let her go. Nevsky, who was a student of biology at the University of St. Petersburg when Von Plehve was assassinated, was arrested, but her relatives had sufficient influence to secure her release. They met in Paris, and Nevsky persuaded Olga to go on the stage and come to New York."

"Next to Ekaterina's devotion to the cause is her devotion to science," said Kazanovitch, opening a door to a little room. Then he added: "If she were not a woman, or if your universities were less prejudiced, she would be welcome anywhere as a professor. See, here is her laboratory. It is the best we - she can afford. Organic chemistry, as you call it in English, interests me too, but of course I am not a trained scientist - I am a novelist."

The laboratory was simple, almost bare. Photographs of Koch, Ehrlich, Metchnikoff, and a number of other scientists adorned the walls. The deeply stained deal table was littered with beakers and test-tubes.

"How is Saratovsky?" asked the writer of the doctor, aside, as we gazed curiously about.

Kharkoff shook his head gravely. "We have just come from his room. He was too weak to talk, but he asked that you tell Mr. Kennedy anything that it is necessary he should know about our suspicions."

"It is that we are living with the sword of Damocles constantly dangling over our heads, gentlemen," cried Kazanovitch passionately, turning toward us. "You will excuse me if I get some cigarettes downstairs? Over them I will tell you what we fear."

A call from Saratovsky took the doctor away also at the same moment, and we were left alone.

"A queer situation, Craig," I remarked, glancing involuntarily at the heap of feminine finery on the chair, as I sat down before Kazanovitch's desk.

"Queer for New York; not for St. Petersburg, was his laconic reply, as he looked around for another chair. Everything was littered with books and papers, and at last he leaned over and lifted the dress from the chair to place it on the bed, as the easiest way of securing a seat in the scantily furnished room.

A pocketbook and a letter fell to the floor from the folds of the dress. He stooped to pick them up, and I saw a strange look of surprise on his face. Without a moment's hesitation he shoved the letter into his pocket and replaced the other things as he had found them.
