"In Calcutta?" cried Ralston. "Some months ago, then?"
"Yes."
"How did you come to notice him in the Maidan?" Mrs. Oliver shivered slightly as she answered:
"He seemed to be watching me. I thought so at the time. It made me uncomfortable. Now I am sure. He was watching me," and she suddenly came forward a step.
"I should like to go away to-day if you and your sister won't mind," she pleaded.
Ralston's forehead clouded.
"Of course, I quite understand," he said, "and if you wish to go we can't prevent you. But you leave us rather helpless, don't you?—as you alone can identify the man. Besides, you leave yourself too in danger."
"But I shall go far away," she urged. "As it is I am going back to
England in a month."
"Yes," Ralston objected. "But you have not yet started, and if the man followed you from Calcutta to Peshawur, he may follow you from Peshawur to Bombay."
Mrs. Oliver drew back with a start of terror and Ralston instantly took back his words.
