In his 1883 memoir "Retrospect of a Long Life", Samuel Carter Hall writes of Landon's marriage and husband in very negative terms. "Her marriage wrecked her life; but before that fatal mistake was made, slander had been busy with her fair fame" (Retrospect, p. 395). Landon had taken "refuge from . . . in union with a man utterly incapable of appreciating her or making her happy, and [she went out with him to his government at the Gold Coast -- to die" (ibid.). Her death was "not even -- tragical as such an ending would have been . . . to wither before the pestilential influences that steam up from that wilderness of swamp and jungle" but rather "to die a violent death -- a fearful one" (ibid.). Here Hall asserts his belief that Landon was murdered by her husband's common-law wife: "unhappy 'L.E.L.' was murdered I have had a doubt. . . . She landed at Cape Coast Castle in July, 1838, and on the 15th of October she was dead . . . from having accidentally taken a dose of prussic acid. But where was she to have procured that poison? . . . .It was not among the contents of the medicine-chest she took out from England" (ibid., pp. 395–396). Rather, claims Hall, after arriving in Africa, "Maclean left her on board while he went to arrange matters on shore. A negro woman was there, with four or five children -- his children; she had to be sent into the interior to make room for her legitimate successor. It is understood the negress was the daughter of a king . . . from the moment 'L.E.L.' landed her life was at the mercy of her rival; that by her hand she was done to death I am all but certain" (ibid., p. 396).
