The Remains Of The Day by Kazuo Ishiguro

(used, paperback)
 
In the summer of 1956, Stevens, a long-serving butler at Darlington Hall, decides to take a motoring trip through the West Country. The six-day excursion becomes a journey into the past of Stevens and England, a past that takes in fascism, two world wars, and an unrealised love between the butler and his housekeeper.
