The second novel in Lois H. Gresh's Sherlock Holmes vs. Cthulhu
series.
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. But
can they find the cause of the neural psychoses before Watson himself
succumbs?
