I had my greatest disappointment when it came to tracing Nina Carrington. The woman had gone without leaving a trace. Marked as she was, it should have been easy to follow her, but she was not to be found. A description to one of the detectives, on my arrival at home, had started the ball rolling. But by night she had not been found. I told Gertrude, then, about the telegram to Louise when she had been ill before; about my visit to Doctor Walker, and my suspicions that Mattie Bliss and Nina Carrington were the same. She thought, as I did, that there was little doubt of it. I said nothing to her, however, of the detective’s suspicions about Alex. Little things that I had not noticed at the time now came back to me. I had an uncomfortable feeling that perhaps Alex was a spy, and that by taking him into the house I had played into the enemy’s hand. But at eight o’clock that night Alex himself appeared, and with him a strange and repulsive individual. Homebody Shirt, Hoodie. They made a queer pair, for Alex was almost as disreputable as the tramp, and he had a badly swollen eye.
