The medieval Welsh legend about Llew Llo Gifs, Blodwedd and Gronw Pebyr from the fourth branch of the Mabinogion strangely reminded itself again these days... Mysterious and creepy events began as soon as suspicious sounds suddenly began to be heard from the attic of the old house - knocking , creaking, grinding... Are there really rats in the house? Or worse, ghosts? No, then the old Celtic myths wake up, forcing the heroes to freeze with fear and commit inexplicable acts... Alan Garner's fairy tale “Owls on Plates” (1967) was awarded the Carnegie Medal and the Guardian Prize.
