Janek Mitter stumbles into his bathroom one morning after a night of heavy drinking, to find his beautiful young wife, Eva, floating dead in the bath. She has been brutally murdered. Yet even during his trial Mitter cannot summon a single memory of attacking Eva, nor a clue as to who could have killed her if he had not. Only once he has been convicted and locked away in an asylum for the criminally insane does he have a snatch of insight  but is it too late?
