... while [Millard's] book is neither as infectiously readable as Moorehead’s (which is now outdated) nor as comprehensive and deeply researched as Jeal’s, she does add a new dimension to the story. Perhaps as a corrective to the Anglocentrism of earlier accounts, she brings a third figure into the foreground: Sidi Mubarak Bombay, a formerly enslaved African who acted as guide and interpreter for Burton, Speke and several other explorers over the years. It’s a refreshing shift in emphasis and certainly overdue, but since relatively few details about Bombay survive in the historical record, there are limits to how much Millard can tell us.
