This is an absolute joy if you like: journey novels, gentle humour, English history, PG Wodehouse, & can withstand discussions about whether it‘s smart to bring cheese & tallow on a close boat trip & if you have ever wondered whether the maze at Hampton Court is worth the effort. There‘s no plot, but many extended anecdotes. This book wanders like a drunken tourist. It‘s a book about nothing. A Seinfeldian journey up the Thames and through time.
