In The Slippage, William and Louisa have been married for a long time but Louisa seems depressed and bizarrely wants to buy a house on mysteriously inherited land while William cracks funny jokes but seems to disregard her absence. And it does not get much better, affairs and lost jobs and assorted lies later. The story is well written, the characters, especially the husband, utterly believable, and the whole thing is gloomy. Even the dog dies. Avoid on days when you need a pick-me-up.
