In "An Echo in the Bone" by Diana Gabaldon, the narrator reflects on the advantages of respectability, considering how it could be beneficial in various circumstances. The mention of using elderly ladies as spies raises the idea that their societal roles could provide them with unexpected advantages, allowing them to operate under the radar.
The thought prompts a deeper contemplation about the nature of spies and the effectiveness of those who are overlooked. The narrator suggests that the lack of apparent elderly women in espionage might be a testament to their skillfulness, implying that they could indeed be adept at gathering information without drawing attention to themselves.
