London, February, 1892. Night. Foggy. A clandestine meeting. "I want him dead." One man says to the other. Within minutes, both men are themselves murdered by a man only described as a ghost. This ghost's final words to the contract killer are "I cannot allow you to kill the detective." Scotland Yard Detective Edward Willoughby and his team of police officers are pursuing contract assassin Ronald Alexander. He has already killed five people, all related to a garment factory fire seven years past, in which his entire family perished. Despite Scotland Yard's best efforts, the killer is still at large. And he has an agenda: Kill everyone responsible for the fires.
