Biloxi by Mary Miller
novel about an ordinary man, recently divorced and recently retired, learning to live alone. When Louis accepts a dog from a man who says his wife is allergic he is basically saved from being lonely. He then finds himself in a bit of trouble when the wife wants the dog back and discovers that Louis may have an inheritance coming to him.
This is a nice read and a reflection of a man on his own after having been cared for by women all his life.
