Kill the Dead — Tanith Lee

Kill the dead? How can you slay that which is already slain? Yet...sometimes the dead refuse to stay quiet.

For there are times when the dead have a duty that must be fulfilled. There are times when those must walk who defy God and Nature to do so; those are times of horror and haunting.

Then one must call the exorcist. There is work for the slayer of ghosts in the backlands of the world. There is work for Parl Dro, Ghost-Killer.

This is the story of two sisters who defied him. One did not belong on this earth, one did. But which was the one he must kill? Which was the one he must silence?
