Proof (häftad, eng)

Catherine has spent years caring for her brilliant but unstable father, Robert. When he dies she has more than grief to deal with: there''s her estranged sister, Claire, and Hal, a former student of her father''s who hopes to find valuable work in the 103 notebooks that Robert left behind.

And a further problem: how much of her father''s madness - or genius - will Catherine inherit?
