Witchfinder Vol. 4: City of the Dead (Dark Horse, 2017)

Flesheating corpses and an ancient temple discovered beneath London lead authorities to call upon Edward Grey, Queen Victoria's official occult investigator. But the sinister Heliopic Brotherhood of Ra also has interests in the underground ruins. When they ask for Grey's help, he has to wonder if the threat is great enough to team up with a secret society he's sworn to destroy. Hellboy creator Mike Mignola teams with his new writing partner Chris Roberson (iZombie, Hellboy & the BPRD 1953) and his original Witchfinder collaborator Ben Stenbeck (Frankenstein Undergound) for an occult mystery exploring the darkest corners of London.
