Imogen Grisham has a relationship with her husband, Evelyn, that is probably not unusual when this novel was written, in the 1950s. His job as a barrister being demanding, she feels it is her job to provide a stress-free home life. Unfortunately, since he is difficult to please and often impatient with her, she placates him. Her young son, Gavin, is like his father and treats her with disdain.
Imogen, who is some years younger than her husband, notices his growing friendship with Blanche Silcox but doesn’t worry about it because Blanche, a spinster, is old and unattractive, to her mind. However, Evelyn and Blanche have more in common, and eventually Imogen finds herself being excluded from occasions in which Blanche is included.
Although I thoroughly disliked Evelyn and Blanche, it was hard for me to be sympathetic at times with Imogen because she is superficial and so passive. For example, there is a situation in which Gavin has a serious problem at school while Evelyn is involved in an important case. Instead of going to school herself, she sends her friend Phil to deal with it, I assume because she believes she will be ineffectual. Even Imogen’s best friend thinks, not that Imogen should have gone herself, but that Evelyn would have respected her more if she’d interrupted him at work. Maybe there’s something about mothers going to school at that time that I don’t understand.
However I felt about the characters, this novel is a realistic portrayal of the breakdown of a marriage with all of its hesitations and heart-rendings on the one side and its self-justifications on the other. It is layered and ultimately affecting.

I have The Blush on my TBR, but haven’t read anything else by her. You’ve intrigued me!
The other book by her that I read was Harriet.
This is a title I have heard so often, and intend to read, even if I might be a little bit discourage by your review. But I hang on to your last paragraph.
I liked the book. It’s just one of those modernist novels where no one is completely sympathetic.
I enjoyed this and read that same lovely edition, it’s a heart-rending read even when you want to shake her, isn’t it!
Yes.
