"From the moment when I first became aware of my father's illness I was not entirely free from suspicion; and when at length I saw that your efforts to cure him were only partially successful, and that his symptoms persistently recurred, I was convinced that there was foul play somewhere, though why, I could not at first imagine.  But when Gouroo whispered to my father, hinting at your incapacity, and suggesting that Mafuta should be sent for, my suspicions began to take definite shape, and, although I was not able to verify those suspicions, I finally made up my mind that the whole occurrence was the outcome of a plot between Gouroo and Mafuta--your only enemies--to ruin you.  And these suspicions were confirmed when, after you had been carried away and imprisoned, my father began to mend, even before the arrival of Mafuta upon the scene, while it seemed extraordinary to me that the witch-doctor should know so well the character of my father's ailment, that he was able to bring with him precisely the right remedies for administration.
