This article deals with Jack London's "Good-by, Jack" (1909) , part of his "leper trilogy", in order to reevaluate both it and its author in general. Specifically, the artful combination of Jack Kersdale's story of dethronement with the tragedy of Lucy Mokunui, who, falling from her queen-like position, cries "Good-by, Jack! Good-by!" is elucidated. In addition, I suggest that the narrator does not escape dethronement either, by examining the relation of the dethronement of Mokunui and Kersdale with the narrator and the narration, and the implications of the title "Good-by, Jack."
