Sherlock Holmes, the famous detective of the 19th century, will usher in his final glory in the new era.
In 1910, major members of the "Dagon Club" were murdered one after another, including Holmes's brother Mycroft, whose bodies were beyond recognition. Holmes and Watson follow clues that ultimately lead to an evil legend - the Sussex Sea Devil. Not only that, the entire world is moving towards the inevitable catastrophic battle between the ancient gods and the outer gods.
