A gripping, psychological thriller in the best tradition of film-noir, this is the story of a rich but mentally and emotionally troubled young woman, who, in an evening she can't remember, may have stabbed a man to death. It's also the tale of the former cop -- now a part-time cab driver/and would-be horror writer -- who is determined to prove her innocent. But the truth which his investigation eventually reveals is so shocking that it will be almost impossible to prove. For the true criminal is someone she trusts implicitly, someone who is about to wreak the ultimate revenge -- someone who has tampered not only with the truth but with his innocent victim's very mind.
