Great insights into John Wilson's idealic lifestyle. He obviously still lives for his fishing to regularly go out before dawn in winter!
There's a wide range of topics from exotic overseas expeditions,through game and sea fishing. However, it comes across strongly that John's real motivation and interest stems from river fishing in Norfolk.
The demise of his beloved roach and his resentment at those who allow the cormorants to damage fish stocks unchecked is more than adequately covered throughout the book.
