Chauncey Gardiner is one of the most interesting characters - a must for anyone who wants to be in the know of social references you might hear at a party.
Very short and simple; a sort of pre-cursor to Forrest Gump. An enjoyable and quick read.
This is the movie "tie-in" edition with Peter Sellers on the cover. If you enjoyed the movie and haven't read the novel I recommend it due to the differences between the two.
