Weeks after Sherlock Holmes's death, Dr. John Watson is trying to get on with life. This, however, is easier said than done. When a mysterious Midnight Visitor prowls the streets of London searching for new victims, life is anything but boring. And maybe, both the villain and the hero's identity will surprise you...

Three years after Sherlock's death, everyone is convinced that he's dead and gone- except for one person. John Watson seems to have a lot on his agenda, including, but not limited to, mysteries, plots, murders, solving the identity of the mysterious "J", and being reunited with his only and best friend, the (late?) Sherlock Holmes.
