Contributed by alert reader Phil Dumont, whose words I duplicate here:

The main character, David Helfgoth or something like that, I think, is a gifted but eccentric pianist. In one scene, he is swimming in his pool, with pages of a score (by Ravel, I think) scattered about the yard and the pool. His wife comes out and anxiously tells him he needs to hurry to get ready for a performance, and rushes him inside to get dressed, while she gathers the score, using the skimmer net to get the ones out of the pool. The next scene is inside. David is running around partially dressed looking for an article of clothing, and his wife and some others (I didn't catch who these others were) were drying of pages with hair dryers and fans, and assembling them. One of them says "Page 37 is missing!"
