John Spencer is a man trapped in the past - in the second world war of his childhood. Virtually everything since then is more or less blank. Stewart Norriss, a 17 year old Sheffield schoolboy didn't recognise his mother after hitting his head on a kitchen unit. Keith Warren's memory loss is unique. Tests have failed to identify the problem and some doctors have suggested that he is simulating amnesia. His wife Lorraine doubts this - "Nobody could pretend amnesia for three years, 24 hours a day".
