"Of course not!" she answered, shivering a little.

"Then he has a wonderful double," I declared.

"What is this that is in your mind about him?" she asked.

"I believe," I answered, "that he is personating some one, or rather I have believed it. I believe that he is personating some one else, and is afraid of being recognized by those who know."

"Will it satisfy you," she said slowly, "if I tell you, upon my honor, Capitaine Rotherby, that he is indeed my uncle?"

"I should believe you, Felicia," I answered. "I should then feel disposed to give the whole affair up as insoluble."

"That is just what I want you to do," she said. "Now, listen. I tell you this upon my honor. He is my uncle, and his name is truly Delora!"

"Then why does he leave you here alone and skulk about from hiding-place to hiding-place like a criminal?" I asked.

"It is not your business to ask those questions," she answered. "I have told you the truth. Will you do as I ask or not?"
