Until recently, most people thought that the worst thing about Gunter Grass was his work as a body double for Saddam Hussein.
Now the Nobel-prize winning novelist, has admitted he was in Hitler's SS as a teenager. He says that his public confession has been a great relief to him.
Of course now everybody's saying that the truth should have been obvious all along - his name even ends in "SS"!
There's another writer, a Scottish novelist, who has a secret past in the IRA Bellshill juniors. For obvious reasons I can't identify him, except by his operational codename of Madymira. I think going public would be a load off his mind, and might allow him to give up the self-flagellation.
