F

or once, all the NYPD asks for precise instructions from Sherlock when M, the mysterious killer he couldn't catch in London due to his addiction, resulting from his beloved being murdered, starts his signature killings all over New York. After a corpse is left in his home, Sherlock sets a trap and catches the fiend, hell-bent on illegally merciless revenge, but is made to doubt by an apparently substantiated copycat claim.
