Imagine the old wet streets of London, complete eerie fog and the echoing of horse shoes on cobblestone, masking the presence of a sadistic menace. It's Jack the Ripper and he has struck again. The police are baffled. How did someone butcher their victim in such a condensed area like Whitechapel and not get caught? In reality, Jack the Ripper was never captured or even identified. “Murder by Decree” answers the question of if the Ripper would've evaded the law had Sherlock Holmes taken the case. If that isn't awesome enough, what if the movie in question decided to be a horror film directed by the man who brought us the creepy “Black Christmas”? If that's not the best idea conceived by man, I don't know what is.
