Most people like to read about intrigue and spies. I hope to provide a metaphor for the average reader's daily life. Most of us live in a slightly conspiratorial relationship with our employer and perhaps with our marriage.

The quote is saying that a lot of people find stories about intrigue and spies interesting. The speaker is suggesting that these stories can be compared to the relationships that many people have with their employers and spouses. In both cases, there is an element of mystery and secrecy. This is because the motivations and thoughts of people are sometimes unknown or hard to figure out. The speaker is suggesting that the reader’s daily life can be equally mysterious, even though it might not appear that way on the surface.
