"And you are Doctor Weston, of course," the latter answered with a smile.

"Now," said the doctor, "I will commence, Mr. Standerton, by saying that it is absolutely necessary that I should catch the six o'clock train back to London."

"I will arrange that you do so," Jim replied, and then the doctor surrendered his ticket and they strolled out of the station. "Now, perhaps, I had better tell you my reasons for asking you to come down to-day. Shall we walk a little way along the road. I have no desire to be overheard. I will now make you acquainted with the facts of the case, in order that you may go direct to the house of the gentleman I want you to see."

"He is not a member of your own family, then?" the doctor enquired.

"No, he is no sort of relation. In fact, I had not seen him until a few months ago."

They paused beside a gate and faced each other.

"I gather that it is rather an unusual case?" the doctor remarked.

"A very unusual one," Jim replied. "The matter stands in this way. I am engaged to a young lady who is the adopted granddaughter of the gentleman in question."

The doctor nodded, but said nothing. He listened attentively, while Jim told his tale, explained his fears for Helen's safety, and described the threats the old gentleman had made use of concerning himself.

When he had finished Dr. Weston drew some lines on the ground with the point of his umbrella, as if he were working out a difficult calculation.
