Quis custodiet ipsos custodes?

There is clearly someone in the Office of the Witchfinder General who is working for or with English Wizardry, and Danesh and the Crow are determined to track them down. It might even be one of the Lord High Witchfinders. Who can they trust? Can Danesh even trust the Crow?

  To ensure the traitor is not alerted, Danesh conducts an off-the-books investigation under cover of an inquiry into a cold case. But not all cold cases stay cold; not all dead witches stay dead; and not all traitors stay hidden…

  … and what is the significance of the goat’s skull?
