The narrative, presented as a discovered memoir, utilizes a first-person perspective to expose the hypocrisy of the Victorian era through the eyes of a man who is consistently out for himself. He faces opposition from both ruthless slave traders and the shifting tides of international diplomacy, relying on his trademark cowardice and cunning to survive.
