"Twelve hours, eh?" repeated the officer. "That would bring it to about six o'clock this morning."
"I won't commit myself to a definite time," said Dr. Burrows hastily. "I only say not less than twelve hours. It might have been considerably more."
"Ah!" said the sergeant. "Well, he made a pretty good fight for his life, to all appearances." He nodded at the sand, which for some feet around the body bore the deeply indented marks of feet, as though a furious struggle had taken place. "It's a mighty queer affair," pursued the sergeant, addressing Dr. Burrows. "There seems to have been only one man in it—there is only one set of footprints besides those of the deceased—and we've got to find out who he is; and I reckon there won't be much trouble about that, seeing the kind of trade-marks he has left behind him."
"No," agreed the surgeon; "there ought not to be much trouble in identifying those boots. He would seem to be a labourer, judging by the hob-nails."
"No, sir; not a labourer," dissented the sergeant. "The foot is too small, for one thing; and then the nails are not regular hob-nails. They're a good deal smaller; and a labourer's boots would have the nails all round the edges, and there would be iron tips on the heels, and probably on the toes too. Now these have got no tips, and the nails are arranged in a pattern on the soles and heels. They are probably shooting-boots or sporting shoes of some kind." He strode to and fro with his notebook in his hand, writing down hasty memoranda, and stooping to scrutinize the impressions in the sand. The surgeon also busied himself in noting down the facts concerning which he would have to give evidence, while Thorndyke regarded in silence and with an air of intense preoccupation the footprints around the body which remained to testify to the circumstances of the crime.
"It is pretty clear, up to a certain point," the sergeant observed, as he concluded his investigations, "how the affair happened, and it is pretty clear, too, that the murder was premeditated. You see, Doctor, the deceased gentleman, Mr. Hearn, was apparently walking home from Port Marston; we saw his footprints along the shore—those rubber heels make them easy to identify—and he didn't go down Sundersley Gap. He probably meant to climb up the cliff by that little track that you see there, which the people about here call the Shepherd's Path. Now the murderer must have known that he was coming, and waited upon the cliff to keep a lookout. When he saw Mr. Hearn enter the bay, he came down the path and attacked him, and, after a tough struggle, succeeded in stabbing him. Then he turned and went back up the path. You can see the double track between the path and the place where the struggle took place, and the footprints going to the path are on top of those coming from it."
"If you follow the tracks," said Dr. Burrows, "you ought to be able to see where the murderer went to."
