"And what about Mrs. Hall?"

"Nothing, missy. She was a silent lady. I know very little about her."

"Durban"--Beatrice looked at him keenly--"are you telling me the truth?"

"I am, missy. Why should I tell you a lie? All I know of Mrs. Hall is, that she was the daughter of a West Indian planter, who was my father's master in the time of slavery. I was born on the estate, and afterwards entered the service of Colonel Hall--a captain he was then--to whom I became greatly attached. He saw Mrs. Hall, and fell in love with her. They married, but did not get on well together, for what reason I cannot tell you. They came here to see Mr. Paslow's father, who was an old friend of the Colonel's. Mrs. Hall stopped in London for a time, and then came down for one night with the nurse and her child. My master was murdered, and the necklace disappeared. That is all I know."

"But, Durban, Major Ruck says that the Colonel gave the necklace to my mother before his death."

"That is not true," cried Durban vehemently, and his eyes blazed. "There was no reason why he should give it to--to--Mrs. Hedge. And I saw the necklace in the Colonel's hands on the very night the crime was committed. Yes, and I saw him place it in the green box beside his bed. Next morning the window was open, the Colonel was lying dead with a cut throat, and the Obi necklace was gone. I can tell you no more, and I don't know why you wish to know all this."

"Because," said Beatrice slowly, "it is my belief that the same man with the black patch who murdered Colonel Hall murdered Mr. Alpenny; and in both cases I believe that the murder was committed for the sake of this necklace."

"I did not know that Mr. Alpenny had it, missy."

"Major Ruck says that he had, and married my mother for the sake of the necklace, which doubtless--as it has not been found after his death--he turned into money."

"It might be so," murmured Durban moodily. "Major Ruck knew a great deal about Mr. Alpenny which I did not know. He was a kind of decoy duck to the master--a man about town who brought foolish youths to borrow money. A dangerous man, missy, and one you are well rid of. Missy"--he laid his hand on her arm--"be advised; seek to know no more. Mr. Alpenny's life was not a good one or a clean one. Marry Mr. Paslow, and go away."
