Amusing send up of academe and a mystery story about Cornut, a suicidal mathematician. He's tried to kill himself in his sleep nine times and so have a group of other academics, none of them lasting past the next few attempts. Despite the silliness that they still use magnetic recording tape and film, flapping in the projector, in the far flung future, I like Pohl's Galaxy era style. No nonsense, plot driven storytelling. Plus I have the Ballantine first edition with a marvelously ludicrous cover, a nude girl on a rug watching television, which has absolutely no relation to the book's contents.
