No it's not.
The premise is that he and his family live in a house in Norfolk, and he goes into every room, and then gives you a history of how each room (or the hall for that matter) came into being over time.
However, most of it seems to be a history of America.
Some of it is quite interesting, but I'm giving it a rest for the moment. I only read it on the train home in the evening anyway.
There was one book of his (he was returning to the States, so did a tour of Britain before he left) that had me rolling up with laughter.
He was in a hotel, somewhere on the South Coast if I remember correctly. He was describing the menu for the evening meal.
It was Jus this, and Confit of that, etc. The dessert menu, however, was Jam Roly Poly, Rice Pudding, Treacle Pudding, etc.
His comment........ "When it comes to the British, you can do anything to their main course, but don't ever f**k with their pudding".
