The Newton LetterRead about another entry on the list.
by John Banville (1982)
A middle-aged historian finds that he can not complete his book, distracted as he is by the two women in Fern House, the "big gloomy pile with ivy and peeling walls" on the estate where he is renting a cottage. He ends up sleeping with the wrong woman ("It is strange to be offered, without conditions, a body you don't really want"), having fallen in love with another "wrong" woman: her older, more reserved aunt. In John Banville's later work, he has managed desire's disconnect by focusing on his characters' sense of their own duality. (Banville recently split his own writerly persona in two, creating an alter ego, the thriller writer Benjamin Black). "The Newton Letter" shows the moment of fission; for a slim, allusive book, it contains a great and secret energy.
