There are many bad days in Edinburgh police's subdivision 'The Commission for the Elucidation of Unsolved Cases Presumably Related to the Odd and Ghostly'. And in the pantheon of the worst days - today takes the podium.

 And he tells them that Queen Victoria - the most powerful woman in the world - wants them both dead.
