The Copper Badgers make their appearance in the Ditch as the House of the Griffin lies in wait. Dr Pavel was very clear in his instructions: do not alert the Harmonium, the Bleak Cabal cannot be implicated and if you get all the packages there will be a big reward. It’s their first real challenge as a team, how well can they pull this off and just how dirty can it get when you are fighting in sewage?

The House of the Griffin make their way under the Zaddfum trestle and explore the shantytown built in the shallow part of the Ditch. There they meet a motley crew of children, dubious adults and signs of clandestine of activity. Will their preparations be enough to catch the Copper Badgers unawares?
