This is a farewell walking tour of England by an American expatriate who has decided to return home after two decades. It is full of rich conversations, humorous anecdotes and amusing interactions with the natives who often astonish him (and the reader) with their observations and attitudes. A good-natured tour de force through the country's foibles as well as its charms, this is a congenial companion for any trip to the sceptered isle.  (GBR16, $14.95)
