"The night Arthur and poor old Ichabod returned to us aboard _The Hialdo_ with the Doctor's cap and note, I believed as firmly as you did that the unfortunate man had been swallowed up in the quicksands, or swept away to death by the tide. At the time when he left me alone in the shack in order to go for help, I would not let him go until he had agreed to carry with him sealed orders under which he should act. I wrote these and gave them to him, and he promised to follow my instructions. They were for his future guidance. I believed that, if he followed them, he would not only escape punishment, but reform so as to be of service once more to the world. Naturally, when help did not arrive from Portsmouth, I concluded that his strength had not been sufficient for the task, that he had perished. So, I was not surprised by the news brought to the yacht by the men who had been searching for him. "That morning when I visited Portsmouth, Roy dear, I had two objects in view. One was to verify the fact that Doctor Garnet had not reached the town. The other was to visit the young physician whom I knew to be located there, in order to arrange with him to care for the afflicted man in case he should arrive later on. As I was about to leave the yacht, early in the morning, Captain Ichabod appeared." Ethel's gravity vanished for a moment. Her lustrous eyes narrowed and twinkled. She smiled until the dimples in her cheeks were shadows against the rose. "I suppose he stole away from the fond Sarah while she was asleep. He never could have managed it had she been awake." She became serious again, and Roy, whose mouth had widened in an appreciative grin, again listened with sober attention. "Captain Ichabod had a confession to make to me. That confession was vastly more of a surprise to me, as you will soon understand, than this news in father's letter. The old fellow first swore me to secrecy. Then he out and told me, not without a certain exultation at his shrewdness, that he had put one over on the greatest detective in America, Arthur Van Dusen. He explained that when he and Arthur reached the false inlet where they found the cap and note, he believed that Doctor Garnet had crossed in safety, for the channel was by no means so dangerous as he represented to the detective. As a matter of fact, he hoped and expected to find the Doctor's tracks on the other side, and he did so although he concealed the knowledge of their existence from Van Dusen. Ichabod went on to tell me that he was moved to sympathy in Doctor Garnet's behalf, that he believed the man would reform, would be of use to the world, that he was worth saving from the law's punishment for offenses inspired by a drug-maddened brain. He insisted that he told no lie to Arthur--only allowed the world's greatest detective to draw a few wrong conclusions from his vague remarks and the melancholy expression on his face when he returned after crossing the inlet to look for tracks.
