SHERLOCK NINJA (2009)

"A mysterious killer is stalking the streets of Victorian London, terrorizing its Chinese immigrant community. Scotland Yard enlists the aid of the world's greatest detective, a man who combines a brilliant deductive mind with commensurate skill in the ancient arts of ninjitsu. The evidence he finds all leads to a mysterious figure known as the Iron Monkey. But are the clues really pointing him in the right direction, or is he climbing the wrong tree?"
