ONE:Leona Lalage came to the house at length. So far as she could see no lights were anywhere except in the hall, where there was a faint spot of gas. Everything was going to turn out favourably. Evidently the landlady had gone to bed, or the gas would not be so low. It was easy to pick the latchkey out of the bunch that she held in her hand. The lock turned easily and smoothly, and she was in the hall."That is logical, at any rate. But to go further. You borrowed a man's coat to put over your shoulders. And the coat you borrowed was mine with the latchkey in the pocket. That I got from a footman. And when I came to look for my skeleton plot, it was gone. Then I knew where I had to search. Leona Lalage was at the bottom of the Corner House mystery. It was her hand that I had to force. Once that was done the rest was easy."
