“I knew it,” she said. “I—I think he was here the night before last. That is why I went to the tower room. I believe he would kill me if he could.” As nearly as her round and comely face could express it, Jennie’s expression was tragic at that moment. I made a quick resolution, and acted on it at once.

“You are not entirely frank with me, Jennie,” I protested. “And I am going to tell you more than I have. We are talking at cross purposes.”

“I was on the wrecked train, in the same car with Mrs. Curtis, Miss West and Mr. Sullivan. During the night there was a crime committed in that car and Mr. Sullivan disappeared. But he left behind him a chain of circumstantial evidence that involved me completely, so that I may, at any time, be arrested.”

Apparently she did not comprehend for a moment. Then, as if the meaning of my words had just dawned on her, she looked up and gasped:

“You mean—Mr. Sullivan committed the crime himself?”

“I think he did.”

“What was it?”

“It was murder,” I said deliberately.

Her hands clenched involuntarily, and she shrank back. “A woman?” She could scarcely form her words.

“No, a man; a Mr. Simon Harrington, of Pittsburg.”
