It was exciting to discover that this story is based upon a novel by Cornell Woolrich. Some googling made me learn that the tv series, Rendez-vous en Noir, was made in 77, with Daniel Auteuil as one of the actors. And the boyfriend doesn't kill the killers, he kills their wives or girlfriends. I remembered that wrong. Anyway, the book is ordered and I look forward to reading it. I might set myself up for a disappointment. Will the book make the same impression on me as an adult as the tv series did on me as a kid?
