London, 1854. Strange forces- faerie, magic, and the more bizarre inventions of science- are everywhere, and barely secret. The infamous Kerberos Club is both a shelter for those touched by the Strangeness, and is at the same time dedicated to protecting Queen and Country from the threats offered by the Strange.
The Kerberos Club is given the tip-off that children are going missing in Whitechapel. The odd thing is that the tip-off came from the Baroness Roxanne Murray. Why would a baroness be concerned with goings on in one of the poorest and least reputable parts of the city?
