Everyone believed that Grandfather Anschel had been killed by a Nazi beast, but one day he stands at the door, released from a mental institution: an old, shivering man muttering incomprehensible things to himself. As if he must repeatedly (like back in the camp) tell the Obersturmbannführer new adventures of the famous children's gang, stories that made him famous as a writer. An almost unbelievable story - and yet only half of this internationally award-winning novel. The other half belongs entirely to nine-year-old Momik, who is trying to find out what the grandfather might be murmuring, telling, or experiencing.
