I have read this a few times because I love Ms. Sharp's writing style -- it is a beautifully drawn picture of a household of British civilians at loose ends at the end of WWII, having to share accommodations with other people that they really would prefer not to be with. The mistress of the household is an elderly widow, and although she has a reputation for being foolish (hence, the title), she is goodhearted. The domestic drama arises from the woman's conviction that she should invite a distant cousin to join the household to atone for her bad behavior towards this relative when they were young girls. The cousin, a classic "poor relation", has an overwrought and anxiety-ridden personality which probably resulted from years of precarious employment in various households as a ladies' companion. She is unlikable and mean-spirited, seeking out gossip and attempting whenever she can to disrupt the lives of the others. The mistress of the household tries to sooth her busybody cousin and convince her that she has a permanent home with them, and more. The other members of the household are adamant that this decidedly difficult person entering their family circle is not to be borne and do their best to try to get her to leave. Margery Sharp manages to make it all work out and tells a very compelling story about people who are not at their best trying to make the best of a difficult situation.
