"Do you know who lives at that farm?" enquired Mr. Hobhouse speaking very distinctly. "Tolly, you say? Oh, jolly? Yes, very jolly! Ha, ha! Good-bye, my lad, good-bye to you!" Jock's hoot of laughter was answered by Mr. Hobhouse's giggle, and they set off down to the farm, the antiquary in front limping rather more markedly than usual, and the idiot rambling behind. The visit to the Scollays was a distinct success, so far as establishing the personality of Mr. Thomas Sylvester Hobhouse went. At first they looked at him with an obvious suspicion and replied to his questions with a reticence that gave him a few uneasy moments. But in ten minutes his indefatigable friendliness had conquered the household and he knew that he was safe to visit that knoll whenever the fancy took him. Peter senior told him a long story about the fairies who were seen dancing round the knoll in his father's time, and though his family were evidently a little distressed by his reference to anything so unfashionable, and Jock hooted several times, their visitor exhibited the liveliest interest and put the tale religiously down in his note book. This was all that could be done at the moment; the establishment of a perfectly harmless reputation and of a natural reason for visiting that particular place at odd times. Mr. Hobhouse obtained permission to do a little digging there if he desired it, and parted with the family on the best of terms. "Slow work!" he said to himself as he struck out for home, with his limp rapidly vanishing. "But what the devil else can one do? What is there definite to take hold of?" That was the baffling feature of the business. As my cousin said, such scent as there was had grown cold by this time, and one had to begin at the beginning again. And so far there seemed to be no beginning. The detectives of fiction might have found some clue to start a train of logical and inevitable reasoning that led straight to the criminal, but the detective of fact had utterly failed, and the brilliant young amateur of fact was likewise completely at sea. What good for instance had my visit to the Scollays done? I asked myself. If they were innocent I had wasted my time. If they were guilty, what had I discovered to bring it home to them? Absolutely nothing! And the same with each inhabitant of that island whom I had seen. Some cunning and powerful organisation was certainly at work, to the detriment of my country, but the only point I had scored against them, was that I had got into the place without their recognising me. At least I presumed I had or I should scarcely still be alive to tell the tale--unless they had grown either more merciful or more timid since I was here last. And their continued immunity would scarcely be likely to produce either of those effects.
