Operation Shylock: a confession - Philip Roth

In this book (which may or may not be fiction), Philip Roth meets a man who may or may not be Philip Roth. Because someone with that name has been touring Israel, promoting a bizarre reverse exodus of the Jews. Roth is intent on stopping him, even if that means impersonating his own impersonator.

With excruciating suspense, unfettered philosophical speculation, and a wild cast of characters, Operation Shylock barrels across the frontier between fact and fiction, seriousness and high comedy, history and nightmare.
