In Patrick O'Brian's "The Reverse of the Medal," the speaker passionately defends their integrity against an accusation of being a spy or informer. They express disdain for the suggestion that they are motivated by money or loyalty to a superior, insisting that their actions are driven by personal conviction rather than external influences. The emotive language underscores their frustration with the person's misguided assumptions.

The reference to "Christ's blood in heaven" adds a layer of solemnity and seriousness to their rebuttal, suggesting that the speaker's honor and principles are sacred. This intensity highlights not only their moral stance but also the broader theme of integrity versus manipulation in the narrative, capturing the essence of human dignity in conflict.
