There had by this time appeared the sheriff of Tullahoma County, who brought with him the most practical agencies of justice possible for that peculiar country, three dogs known widely as skilled followers of human trails. To the sheriff Eddring now offered the newly discovered handkerchief. The latter held it out to the dogs, which sniffed at it gravely, and sniffed also at the place where it had been found under the derailing timbers. The sheriff went about his duties methodically, now moving back all the spectators so that the dogs might have full opportunity in their work. The tail of the lead dog at length began to move slowly from side to side. He walked a pace or so down the bank and paused, the other two coming to him. The sheriff pointed silently. Distinctly marked in the soil was the print of a shoe--a woman's shoe, long, narrow. All three of the dogs now moved toward a gap in the row of stumps which formed a rude hedge for the cleared right of way. At this little gap the narrow footprint was seen again, with others made by bare feet. At the edge of the wood, there came a long, low, sobbing call from the lead dog, and presently the others wailed their confirmation; so that the trail was now steadily begun. They followed the dogs for miles, across glade and ridge and opening, through jungles of vines and matted cane; and presently they came upon paths which converged, separated and converged again, as might have been in the jungle about a village of the Black Continent. They went on and on, and finally they came out, as John Eddring in his heart knew they presently would, at the edge of a little hidden opening, surrounded by a wall of deep green cane. There before them stood a long, low, log structure, which he himself could have described in advance. Upon the door, done in the blind, morbid egotism of crime, which so often leaves open sign and signal for its own undoing, there showed, cut deep in the jamb, a rude sign, cabalistic, mysterious, fetish-like. To Eddring it seemed for the instant to be the same mark as that upon the handkerchief. He could not explain these things in his own mind. Others of the party were more interested in pointing out once more, in the confusion of footprints before the building, the imprint of the same narrow shoe. Eddring was striving to connect this imprint with the mark on the handkerchief and on the door, with certain things which he had heard on this very spot long before; and with that glimpse of a woman's garb in the darkness at the time of the night attack on the Big House.
