The Latecomer by Jean Hanff Korelitz

 

Liked this a great deal. Very different from THE PLOT until the middle of the book where, indeed, there is a rather large plot swerve. The concept of triplets as never before recorded -- including how many persons that actually implies.  The high-art, wealthy milieu gets a bit wearying, but Korelitz' prose is glittering, at least.
