A London P.I. investigates the disappearance of a young woman with ties to a secret cult whose roots run deeper than he imagined Arlo Abbas has never shied away from a challenge. As a private investigator in London with a complicated past, he doesn't have that luxury. But when he finds £10,000 deposited into his nearly empty bank account and a note stuffed in his mailbox that says "Find Sophie Banik," he realizes this is no ordinary missing-persons case.
Arlo's search soon reveals that Sophie was murdered five months ago, a clandestine lab is performing human trials that blur the lines between life and death, and an underground organization--part cult, part bizarre scientific experiment--toils toward some unknown end deep in the bowels of the earth.
