"Who is this gentleman, Dorise?" asked Hugh, when a moment later the girl and her companion had recovered from their surprise.
"I cannot introduce you," was her reply. "He refuses to give his name."
The tall man laughed, and said: "I have already told you that my name is X."
Hugh regarded the stranger with distinct suspicion. It was curious that he should discover them together, yet he made but little comment.
"We were just speaking about you, Mr. Henfrey," the tall man went on. "I believed that you were still in Belgium."
"How did you know I was there?"
"Oh!--well, information concerning your hiding-place reached me," was his enigmatical reply. "I am, however, glad you have been able to return to England in safety. I was about to arrange a meeting between you. But I advise you to be most careful."
"You seem to know a good deal concerning me," Hugh remarked resentfully, looking at the stern, rather handsome face in the moonlight.
"This is the gentleman who sought me out in Nice, and first told me of your peril, Hugh. I recognize his voice, and have to thank him for a good deal," the girl declared.
"Really, Miss Ranscomb, I require no thanks," the polite stranger assured her. "If I have been able to render Mr. Henfrey a little service it has been a pleasure to me. And now that you are together again I will leave you."
"But who are you?" demanded Hugh, filled with curiosity.
"That matters not, now that you are back in England. Only I beseech of you to be very careful," said the tall man. Then he added: "There are pitfalls into which you may very easily fall--traps set by your enemies."
"Well, sir, I thank you sincerely for what you have done for Miss Ranscomb during my absence," said the young man, much mystified at finding Dorise strolling at that hour with a man of whose name even she was ignorant. "I know I have enemies, and I shall certainly heed your warning."
"Your enemies must not know you are in England. If they do, they will most certainly inform the police."
"I shall take care of that," was Hugh's reply. "I shall be compelled to go into hiding again--but where, I do not know."
"Yes, you must certainly continue to lie low for a time," the man urged. "I know how very dull it must have been for you through all those weeks. But even that is better than the scandal of arrest and trial."
"Ah! I know of what you are accused, Hugh!" cried the girl. "And I also know you are innocent!"
