Sooner or later, all vampires go mad . . . A killer stalks the rain-shrouded streets of Victorian London, leaving a trail of brutalized, bloodless corpses in his wake. While most suspect Jack the Ripper has returned, a select few know that a far darker force is at play. Charlotte Murray, a socialite with a secret, is plagued by nightmares of a beautiful young man with a strange hunger. Gabriel Harding, her childhood love, now a charming and charismatic man-about-town, can no longer outrun the demons from his past. Leo Eriksson, an unwilling, centuries-old vampire, is losing his grip on reality. The three soon find themselves embroiled in a web of death, obsession, madness, and revenge as they investigate the horrific killings, drawing ever closer to the enigmatic figure at the heart of it all.
