A strange new act has arrived at the fairground. Who is Grinpayne and how did he get his hideous smile? Helped by an old man, a lone wolf and a blind girl, his story must be told. The epic tale of an abandoned child with a terrible secret. A disfigured youth who is desperate to hide and a sightless girl who longs to be discovered. Let the darkness seduce you.
