"And all the time no one else has been to see you or written to you?" I asked.

"No one!"

She smothered a little sob as she answered me. It was as though my questions and Mabane's, although I had asked them gently enough, had suddenly brought home to her a fuller sense of her complete loneliness. Her eyes were full of tears. She held herself proudly, and she fought hard for her self-control. Arthur glanced indignantly at both of us. He had the wit, however, to remain silent.

"There are just one or two more questions, Isobel," I said, "which I must ask you some time or other."

"Now, please, then," she begged.

"Did Major Delahaye ever mention his wife to you?"

"Never."

"You did not even know, then, when you arrived in London where he was taking you?"

"I knew nothing," she admitted. "He behaved very strangely, and I was miserable every moment of the time I was with him. I understood that I was to have a companion and live in London."

I felt my blood run cold for a moment. I did not dare to look at Mabane.
