Free Fall [EPUB ebook] 

Sammy Mountjoy, artist, rises from poverty and an obscure birth to see his pictures hung in the Tate Gallery. Swept into World War Two, he is taken as a prisoner-of-war, threatened with torture, then locked in a cell of total darkness to wait. He emerges from his cell transfigured from his ordeal, and begins to realise what man can be and what he has gradually made of himself through his own choices. But did those accumulated choices also begin to deprive him of his free will.
