It had indeed lasted three days, but Roddy would never know that, during those three days, he had been incarcerated in the Kafir kraal on the hillside, outside the aloe hedge. It was only when the golden wig was washed up from the river that the mysterious kraal people, silent and impassive, seemingly ignorant of all but their duties, yet knowing every single thing that passed at the farm, even down to the use of the false hair (though Bernard van Cannan himself had never suspected this), gave him back to those who awaited.
If Dick Saltire had not so thoroughly understood the native mind and inspired the confidence of his boys, the truth might never have been known. As it was, it lay in his power to relate to those whom it concerned that a certain woman named Sophy Bronjon, formerly nurse to the van Cannans, and sent away by them to be conveyed to Robin Island because she had developed leprosy, had never left the precincts of the farm, but stayed there, brooding over the little ones she loved. The kraal people to whom (though a mission-educated woman) she belonged had hidden and sheltered her. Through Meekie's instrumentality, she undoubtedly knew all that passed on the farm, and as surely as she had noted the fate of the van Cannan heirs, she recognized Christine as an ally and friend, and had warned her as best she could of the dangers that beset Roddy. It was she who had sighed and whispered through the closed shutters, frightening Christine at first, but in the end engendering trust, and it was she who, on hearing of the narrow escape of Roddy from the tarantula, had made up her mind to spirit him, with the aid of Meekie and the storm, from the farm and its dangers until the return of his father.
With the disappearance of Mrs. van Cannan and the death of Saxby, the menace was removed and the child brought back as silently as he had been taken away. Even he knew no more than that he had dreamed a strange dream.
Saltire went to meet Bernard van Cannan at Cradock, taking with him the papers left in his care by Richard Saxby. There was not so much to explain to the owner of Blue Aloes, as might have been expected. The doctor who treated him for neuritis and found him dying of slow poisoning by antimony had lifted the scales from his eyes, and a little clear thought, away from the spell of the woman known as Isabel van Cannan, had done much to show him that the sequence of tragedies in his home was due to something more than the callousness of fate. Thus he was, in some measure, prepared for Saxby's confession, though not for the fact that the woman he had adored to fanaticism had never been his wife, or more to him than might have been an adder gathered from his own aloe hedge, with all the traits and attributes peculiar to adders who are gathered to the bosom and warmed there.
