A sardonic look at upper class lefties in the 30s. Brutal prose. Lewis understands the darkness of the human heart as well as, say, Green or Waugh, he writes as well, but here he is, neglected as ever, even on Amazon (where people would review an elephant's fart) without a review - at least til I have stepped in. If you are considering a Lewis book, this (along with Tarr and Snooty Baronet) is one of his most readable.
Very modern style - doesn't date at all. Lewis's art is good too. He is misanthropic, I'll concede. If you are looking for a writer full of the milk of human kindness, then, Wyndham is not for you. On the other hand if you think might enjoy the company of a prose master, with a healthy contempt for the apes of god Lewis is your man.
