A case of death by burning seems straightforward when a perfect match comes up on the STN-J database. The suspect has died leaving a note confessing to three murders, but two have yet to occur. When the second person on the list dies in the same manner as the first, is it a case of murder beyond the grave or a new facet of witchcraft?

A witch using electricity kills two men and disappears. STN-J knows he's hiding in Walled City, but the place is a maze and no one wants to talk. And once they've found the witch, they still have not discovered where his power came from.
