"The reward?"

"No; although Blair, and, I believe, Cicero, intend to work for that. The hope lies in the chance that Brown, whoever he is, may have taken away the body for blackmail. In that case we may get a letter demanding money--probably a large sum. We must pay it, and have your father's remains brought back."

"And the murder, Alan?"

"Ah! that is a difficult part. When Brown stole the body he did not intend to commit murder; that came about in some unforeseen way. The danger that he may be arrested for the murder may keep Brown from applying for blackmail, always supposing, Sophy, that such is his object."

"In that case we may never recover poor father."

"I am afraid not. However, we must live in hope."

This conversation ended in the usual unsatisfactory way. On the face of it there was nothing to be done, for Alan could obtain no clue. Brown, if Brown were indeed the guilty person, had managed so cleverly that he had completely cut his trail. Even the offer of the reward brought forth no fresh information. The mystery was more a mystery than ever.

In his capacity of trustee, Alan had looked through the papers of the dead man. He found no documents or letters whatever relating to his life in Jamaica, yet there were plenty dealing with his doings in South Africa. Twenty years before he had left Kingston with the child Sophy. He brought her to England, and placed her in the Hampstead convent. Then he sailed for the Cape, and had made his fortune there. Fifteen years after he returned, to buy the Moat House, and settled. Sophy came to live with him, and he had passed a quiet, peaceful time until his sudden death. So far all was clear; but the Jamaica life still remained a mystery. When he died he was over sixty. What had he done with himself during the forty years he had lived in the West Indies? Joe could have told; but Joe, as mysterious as his master, had disappeared, and even if he had remained, Alan could have got nothing out of him. The old sailor, as had been proved both by Thorold and the inspector, was as dumb as an oyster.

"Did Marlow ever mention Jamaica?" Alan asked Mr. Phelps, when next they met.

"Once or twice, in a casual sort of way. He said he had sailed a good deal amongst the islands."
