"I must go," she said; "there is a train back to town immediately, and I want to cross to the other platform."

"I will see you into the train if you will allow me."

"You will be sure not to mention that you saw me here," she said.

"I may speak of it, I suppose, to Miss Keys?"

"I wish you would not."

"I won't promise, Miss Aylmer. I am very uncomfortable regarding the position you are in. It is hateful to me to feel that you should come here like a thief in the night, and stay for hours at the railway station. What mystery is there between you and Miss Keys?"

Florence was silent.

"You admit that there is a mystery?"

"I admit that there is a secret between us, which I am not going to tell you."
