While Millard does not belabor her narrative with the excruciating day-to-day details of Burton's and Speke's expeditions, as so many writers have done for us before, she does thoroughly address the infamous Burton-Speke rivalry as it developed in some detail. Some readers might accuse her of being rather pro-Burton, but I see her as trying to be fair and to adjust somewhat the pro-Speke bias of many of the historians of the discovery of the source of the Nile. River of the Gods: Genius, Courage, and Betrayal in the Search for Source of the Nile: By CANDICE MILLARD, New York, Doubleday, 2022, xii + 353 pp., notes, select bibliography, index, $32.50 (HC).
