The novel was about a boat trip that the narrator took to thames river along with his friends. He goes on rambling about the trip and takes the time to digress or go off topic to tell anecdotes. What was really memorable about the book was the places visited which were described beautifully.
Apparently Jerome got the inspiration from one of his trip to the thames for his honeymoon in 1888, and his experiences provided him the subject material for the novel.
