Gideon Smith and the Mask of the Ripper

In book three of this acclaimed Steampunk series, the action moves back to London, and the seedy underworld of the capital of the British Empire. One character is arrested on a murder charge and faces the death penalty, another is cast adrift in Londons underbelly shorn of their memory. There will be old secrets the British Empire thought long dead coming back to cause problems, and London itself is set to stand on the brink of anarchy.
