Stoker & Bash: The Fangs of Scavo

At Scotland Yard, DI Timothy Stoker is no better than a ghost. A master of arcane documents and niggling details who, unlike his celebrity-chasing colleagues, prefers hard work to headlines. But an invisible man is needed to unmask the city's newest amateur detective, Hieronymus Bash. A bon vivant long on flash and style but short on personal history, Bash just may be a Cheapside rogue in Savile Row finery.
When the four fangs of the Demon Cats of Scavo-trophies that protect the hunters who killed the two vicious beasts-disappear one by one, Stoker's forced to team with the very man he was sent to investigate to maintain his cover. He finds himself thrust into a world of wailing mediums, spiritualist societies, man-eating lions, and a consulting detective with more ambition than sense. Will this case be the end of his career, or the start of an unexpected liaison? Or will the mysterious forces at play be the death of them both?
And just who is Hieronymus Bash?
