In the Enemy's House

The story of the agent and code breaker feels so specific and intense—I'm curious what drew the author to this chapter of espionage history.

The descriptions of code-breaking and covert operations really brought the espionage world to life. Did others feel the same sense of intrigue or was it overwhelming?

There are so many figures involved, but the focus on specific individuals made the story so compelling. Wondering what guided these choices.
