A Shadowed Love by Fred M. White

Paul Spencer, Lord Stanmere, stood facing Martlett like a man in a dream. It seemed to him that the clouds had gathered from all sides to overwhelm him. So this man had been hunting him, too, and had at length found him. He could fight no longer.

-"If I must, I must," he said. "I knew Maxwell years ago. His mother lived near Stanmere. We were great friends at one time. We exchanged photographs. I have them at home now. And he used to come to England occasionally to see that eccentric old mother of his and bring me news of Stanmere. But I killed a man who was his partner, you see."
