And here was the problem clearly defined⁠—as strange a one as had ever confronted me. The man had not been on the beach more than a quarter of an hour at the most. Stackhurst had followed him from The Gables, so there could be no doubt about that. He had gone to bathe and had stripped, as the naked footsteps showed. Then he had suddenly huddled on his clothes again⁠—they were all dishevelled and unfastened⁠—and he had returned without bathing, or at any rate without drying himself. And the reason for his change of purpose had been that he had been scourged in some savage, inhuman fashion, tortured until he bit his lip through in his agony, and was left with only strength enough to crawl away and to die. Who had done this barbarous deed? There were, it is true, small grottos and caves in the base of the cliffs, but the low sun shone directly into them, and there was no place for concealment. Then, again, there were those distant figures on the beach. They seemed too far away to have been connected with the crime, and the broad lagoon in which McPherson had intended to bathe lay between him and them, lapping up to the rocks. On the sea two or three fishing-boats were at no great distance. Their occupants might be examined at our leisure. There were several roads for inquiry, but none which led to any very obvious goal.
