His harmlessness had been absolutely guaranteed, provided always that no restraints were put upon him and that any little innocent fancy was indulged. Thus he wandered all over the island and at all hours, sometimes even wandering out at night when the foolish fancy took him, until this was accepted as the normal thing for harmless Jock. Another innocent whim he had of making a collection of rubbishy odds and ends and keeping them in a box in the barn. He had even repeated "Lock! Lock!" and stamped his harmless foot till they good-naturedly provided him with a lock and key for this treasure chest. And thus long before August, 1914, Jock was provided with a character that rendered his habits above suspicion, and a strong box which nobody would ever dream of examining. Two or three times the same polite tourist paid a visit to the island to see how the poor demented young man was being looked after, and on these occasions he would take Jock out for quite a long walk, and afterwards assure the family that their guest's health was benefiting greatly. But this gentleman had not visited the island since the war, it seemed. This was the Scollays' story and I think we all believed that in the main it was true. In fact, since then it has stood the test of all the evidence that could be got to check it. At the same time it seemed pretty clear that their greed had made them blinder than any one without a strong monetary interest could possibly have been. For fear of losing their little gold mine they had shut their eyes when people of average common sense would have opened them pretty wide. Our questions convicted them of this much, and at the end Whiteclett said emphatically that the two Peters must depart that night with him for further examination, if for nothing more. "I'll leave you here with them, sir, for a moment, while I have a look at the other prisoner," he said quickly before our uncle could begin to issue the commands that we knew were coming, and with a sign to Jean and myself, hurried out. We were at his heels and followed him to the barn. There Jock was still lying bound with the doctor sitting over him. "Has he said anything to you?" asked my cousin when he had called the doctor aside. Dr. Rendall smiled under his grey moustache. "He offered me L200 in gold to be paid on the nail if I would let him loose. We must have a dig for that money to-morrow, Whiteclett." "Anything else?" "Not a word after I had refused, and it's my belief you'll never get another word out of the man between now and his execution." "He seems that sort," my cousin agreed. "And now, doctor, you and I will carry him into the house and keep Sir Francis company. The three of us will have an eye on all the prisoners then, till I can get some fellows up from the drifter to escort them. Do you mind going down to the boat, Roger, and sending up a party? You can find your way in the dark?" "I'll make a shift to."
