Affirmation 

Peter Sinclair is tormented by bereavement and failure. In an attempt to conjure some meaning from his life, he embarks on an autobiography, but he finds himself writing the story of another man in another, imagined, world, whose insidious attraction draws him even further in …THE AFFIRMATION is at once an original thriller and a haunting study of schizophrenia; it has a compulsive, dream-like quality.
