After the events in Coldbay where they sealed the hell hole, Lucy is trying to learn more about it and how to save Murzzzz from eternal damnation. Yes, he’s a demon and all, but he’s also a part of the family. Lucy’s turned to her diocese for guidance but they’ve gone strangely quiet so she persuades the Rooks to drive there so they can sort this out. On the way, they realise something is incredibly wrong with a motorway service station - it’s empty except for lingering, sad ghosts and… oh no, another hell hole has opened up and sucked in a load of people. They know they need to stay until they can rescue them and close it down, but not before they’ve done everything in their collective power to rescue Murzzzz. After all, one man’s hellhole is a family of ghost-hunter’s opportunity to save their demon friend. That’s the expression, right?
