But now Theodore discovered a serious oversight. Reading through Aurelian’s papers a second time, he came upon that passage which detailed all that could be learnt of the descendants of Arthur Sibbold. This Arthur, Aurelian wrote, or his descendants, was the most dangerous of all. He was the man who ought to have succeeded to the farm which James Sibbold took possession of. James, or James’s sons, had not the slightest right to dispose of the farm to Sternhold Baskette; they were selling what did not belong to them. Arthur was of course dead, but Arthur’s heirs still lived; and then followed the address and further particulars. These heirs were at present quiet; but if they discovered the register of Arthur’s marriage, Aurelian could not see what was to prevent them from putting in a claim far superior either to Marese’s or to that of any other person. Even if they could not get possession, the Courts would certainly order an immense sum to be paid to them, as compensation; and Aurelian thought himself that nothing in the world could prevent them taking the property which stood on the site of the farm, if not the Swamp. The property on the site of the farm, he thought, must go. “Now,” said Theodore, “what is the use of destroying the American claimants _en masse_ if this even greater danger is to be allowed to remain close at home, within easy reach of the estate, ready at any moment to burst upon us and render nugatory all our risk and labour?” Marese was thunderstruck. For a time it seemed that their enemies were hydra-headed—no sooner was one head cut off than three sprouted up in the place. But the man was not one to be daunted. This also must be done, he said. They had not much time now to lose. It was already the middle of September, and a fortnight must be reckoned for the passage of the yacht to New York. They spent anxious days and nights considering a variety of plans. There is not time to unravel the strange mazes of the mind and trace the genesis of the idea which at last suggested itself to Theodore. It was only one degree less ingenious, and if anything still more horrible, than the infernal machine of Marese. Theodore still continued the asylum at Stirmingham. It was an important source of income, in fact. In that asylum there were confined lunatics of all degrees of insanity, most of them having wealthy friends, and some the representatives of large properties. Among these was one more remarkable than the rest. He was the representative of a long line of lunatics, or semi-lunatics. Popular tradition accused a progenitor living two centuries before of a crime too dark to be mentioned, and believed that the lunacy of his descendants was a special punishment from heaven. This particular individual had seemed tolerably sane till he was permitted to marry—a cruel thing. He then rapidly developed his inherited tendencies, living as a married man, left more free from restraint by friends and others.
