'It was a dark winter afternoon when Helen Graham received two callers. In that dingy London room she made a decision that turned her life into a living nightmare.
'TORMENTED by the strength of Cedric Crome and the weakness of her son Maurice.
'HAUNTED by the person Maurice called 'The Grey Lady'.
'TERRIFIED because she was being forced to turn back–ultimately in defence of her own life.'
