Walking through my local Dollar Bookstore I found a Sunset book with a cover that looked very familiar.
I didn't recognize the house, or the pool, but I did recognize the splash. It looked like that David Hockney
painting - the one with the pool that someone had just dived into.
This is A Bigger Splash from 1967, painted when Hockney was teaching painting at UC Berkeley.
That name, A Bigger Splash is like a movie sequel, and it was.
