Sherlock Holmes vs. Cthulhu

A series of grisly murders rocks London. At each location, only a jumble of bones remains of the deceased, along with a bizarre sphere covered in strange symbols. The son of the latest victim seeks the help of Sherlock Holmes and his former partner, Dr. John Watson. They discover the common thread tying together the murders. Bizarre geometries, based on ancient schematics, enable otherworldly creatures to enter our dimension, seeking to wreak havoc and destruction. 

Amelia Scarcliffe’s monstrous brood, harbingers of Cthulhu, will soon spawn. Her songs spell insanity, death...and illimitable wealth. And Moriarty will do anything to get his hands on gold, even if it means tearing down the walls between this world and a realm of horrors. Meanwhile, after Sherlock Holmes’s last tangle with the Order of Dagon, horrifying monsters haunt the Thames, and madness stalks the streets of Whitechapel. Gang war between Moriarty’s thugs and the powerful cult can only bring more terror - unless Holmes and Dr. Watson can prevent it.

The deadly dimensions over London have been sealed, and the monsters have departed. But word has come to Sherlock Holmes and Dr. Watson of a more terrifying creature still - the great Cthulhu has been sighted off the waters of Innsmouth, Massachusetts. Only Holmes can defeat him. And in the muddy village of Innsmouth, surrounded by villagers who are more sea-monster than human, Holmes meets again his nemesis, Moriarty, and yet greater foes: Amelia Scarcliffe and Maria Fitzgerald, harbingers of Dagon, who have called forth Cthulhu.
