Adam Salton, though he talked little, did not let the grass grow under his feet in any matter which he had undertaken, or in which he was interested.  He had agreed with Sir Nathaniel that they should not do anything with regard to the mystery of Lady Arabella’s fear of the mongoose, but he steadily pursued his course in being prepared to act whenever the opportunity might come.  He was in his own mind perpetually casting about for information or clues which might lead to possible lines of action.  Baffled by the killing of the mongoose, he looked around for another line to follow.  He was fascinated by the idea of there being a mysterious link between the woman and the animal, but he was already preparing a second string to his bow.  His new idea was to use the faculties of Oolanga, so far as he could, in the service of discovery.  His first move was to send Davenport to Liverpool to try to find the steward of the West African, who had told him about Oolanga, and if possible secure any further information, and then try to induce (by bribery or other means) the nigger to come to the Brow.  So soon as he himself could have speech of the Voodoo-man he would be able to learn from him something useful.  Davenport was successful in his missions, for he had to get another mongoose, and he was able to tell Adam that he had seen the steward, who told him much that he wanted to know, and had also arranged for Oolanga to come to Lesser Hill the following day.  At this point Adam saw his way sufficiently clear to admit Davenport to some extent into his confidence.  He had come to the conclusion that it would be better—certainly at first—not himself to appear in the matter, with which Davenport was fully competent to deal.  It would be time for himself to take a personal part when matters had advanced a little further.

If what the nigger said was in any wise true, the man had a rare gift which might be useful in the quest they were after.  He could, as it were, “smell death.”  If any one was dead, if any one had died, or if a place had been used in connection with death, he seemed to know the broad fact by intuition.  Adam made up his mind that to test this faculty with regard to several places would be his first task.  Naturally he was anxious, and the time passed slowly.  The only comfort was the arrival the next morning of a strong packing case, locked, from Ross, the key being in the custody of Davenport.  In the case were two smaller boxes, both locked.  One of them contained a mongoose to replace that killed by Lady Arabella; the other was the special mongoose which had already killed the king-cobra in Nepaul.  When both the animals had been safely put under lock and key, he felt that he might breathe more freely.  No one was allowed to know the secret of their existence in the house, except himself and Davenport.  He arranged that Davenport should take Oolanga round the neighbourhood for a walk, stopping at each of the places which he designated.  Having gone all along the Brow, he was to return the same way and induce him to touch on the same subjects in talking with Adam, who was to meet them as if by chance at the farthest part—that beyond Mercy Farm.

The incidents of the day proved much as Adam expected.  At Mercy Farm, at Diana’s Grove, at Castra Regis, and a few other spots, the negro stopped and, opening his wide nostrils as if to sniff boldly, said that he smelled death.  It was not always in the same form.  At Mercy Farm he said there were many small deaths.  At Diana’s Grove his bearing was different.  There was a distinct sense of enjoyment about him, especially when he spoke of many great deaths.  Here, too, he sniffed in a strange way, like a bloodhound at check, and looked puzzled.  He said no word in either praise or disparagement, but in the centre of the Grove, where, hidden amongst ancient oak stumps, was a block of granite slightly hollowed on the top, he bent low and placed his forehead on the ground.  This was the only place where he showed distinct reverence.  At the Castle, though he spoke of much death, he showed no sign of respect.

There was evidently something about Diana’s Grove which both interested and baffled him.  Before leaving, he moved all over the place unsatisfied, and in one spot, close to the edge of the Brow, where there was a deep hollow, he appeared to be afraid.  After returning several times to this place, he suddenly turned and ran in a panic of fear to the higher ground, crossing as he did so the outcropping rock.  Then he seemed to breathe more freely, and recovered some of his jaunty impudence.

All this seemed to satisfy Adam’s expectations.  He went back to Lesser Hill with a serene and settled calm upon him.  Sir Nathaniel followed him into his s............
