"She can't help it if she doesn't know. And the only way to spoil the game of Felix is to bring the two women face to face. Their mutual jealousy will do the rest, and instead of going to the altar Felix Briarfield will find himself bound for the scaffold."

"True enough! Well, I'll try, Merrick, but it's a job I don't like."

He laughed at my scruples, and tried to show me that I was really doing Olivia a service in being so plain-spoken, but in spite of all his arguments I departed from his house in low spirits. I did not relish the idea of interviewing Olivia on so delicate a subject, yet I saw it was imperative, and therefore made up my mind to carry through the business at whatever cost of personal inconvenience to myself. That is the worst of being an amateur detective: one's feelings are not under sufficient control.

The next day I called at Swansea Square, and sent up my card to Olivia. As it so happened, her mother had gone down to Hurlingham with Felix, and she remained at home on the plea of a headache. She sent down a message to the effect that she was unwell, and asked me to excuse her, but I scribbled a few lines on my card asking particularly to see her. This time the servant returned with the information that Miss Bellin would see me for a few minutes, and I was shown into the drawing room. I felt nervous, but, determined to go through with the matter, managed to screw up my courage. It was a most unpleasant task, but very necessary if I wanted to attain my object.

When Miss Bellin entered, I could not suppress a start, so changed was she in outward appearance. As I said before, she was a tall, well-developed, and very beautiful woman, but now she had grown thin, and her face wore an anxious expression. I could not help thinking that she knew something about the tragedy at the Lone Inn, as I could conjecture no other reason for her ill-health and manifest discomposure. She came forward with a nervous smile, and greeted me in a low voice.

"My mother and Mr. Briarfield have gone to Hurlingham," she said, sitting clown on a lounge near which my chair was placed.

"I am not sorry for that," I answered gravely, "as I wish to see you alone."

"What is the matter, Mr. Denham? Have you anything very terrible to tell me?"

"I think it is terrible."

"About Francis?" she demanded anxiously.
