Ferris calls out to her but she is mesmerised by the strange sound. She feels out to an invisible barrier that appears to be set between a series of redundant concrete fence posts... and suddenly vanishes into it! The labourer stumbles disbelievingly to the remains of the fence but finds nothing to credit what he has just witnessed save a discarded handkerchief.
