Supposing after all that he were not guilty, but the sheriff's theory that he had been killed and the body concealed, were true; then who, besides Radnor, could have had any motive for committing the crime? There was nothing from the past that afforded even the suggestion of a clue. The old man seemed to have had no enemies but his sons. His sons? The thought of Jeff suddenly sprang into my mind. If anyone on earth owed the Colonel a grudge it was his elder son. And Jeff had more than his share of the Gaylord spirit which could not lightly forgive an injury. Could he have returned secretly to the neighborhood, and, following his father into the cave, have quarreled with him? Heaven knows he had cause enough! He may, in his anger, have struck the old man without knowing what he was doing, and overcome with horror at the result, have left him and fled. I was almost as reluctant to believe him guilty of the crime as to believe it of Radnor, but the thought having once come, would not be dismissed. I knew that he had sunk pretty low in the nine years since his disappearance, but I could never think of him otherwise than as I myself remembered him. He had been the hero of my boyhood and I revolted from the thought of deliberately setting out to prove him guilty of his father's murder. I spurred my horse into a gallop, miserably trying to escape from my suspicion; but the more I put it from me as impossible, the surer I became that at last I had stumbled on a clue. Automatically, I began adjusting the evidence to fit this new theory, and reluctant as I was to see it, every circumstance from the beginning fitted it perfectly. Jeff had returned secretly to the neighborhood, had taken up his abode in the old negro cabins and made his presence known only to Mose. Mose had stolen the chicken for him, and the various other missing articles. They had resurrected the ha'nt to frighten the negroes away from the laurel walk, and the night of the party Rad, in his masquerade, had accidentally discovered his brother. Jeff demanded money, and Rad undertook to supply it in order to get him away without his father's knowing. That was why he had borrowed the hundred dollars from me, and had written to his brokers to sell the bonds. It was Jeff who was sitting beside Radnor the night they drove across the lawn. But unknown to Rad, Jeff had found his way back and had robbed the safe, and Rad suspecting it, had refused to make an investigation. During the eleven days that intervened between the robbery and the murder Jeff had still been hiding in the vicinity--possibly in the neighborhood of Luray, certainly no longer in the cabins, for he had no desire to meet his brother.
