The Hangman's Ghost

Jacob Good was a man who could expect to see many ghosts. Angry spirits - and the wraiths of men and women filled with hate for Jacob - paraded their soured souls in front of him, surrounding Jacob with their rage.
After all, Jacob had killed a lot of people.
Now, a frightening, tragic ghost is taunting Jacob as he's about to retire, making his life a nightmare, and demanding that Jacob make sure the last guilty murderer doesn't miss his appointment with Jacob's noose. But who is to be Jacob's final victim? And do they deserve to escape the rope, or not? Will Jacob's last killing be a dreadful mistake?
