"Mystery of the Manse pt. 4" is written by Dan Vado and drawn by Mike Moss. In this, our ghost host Master Gracey recounts how he met Emily De Claire, with whom he instantly fell in love. They planned to marry, but William couldn't think of letting her live in a haunted house. Desperate, he calls on Madame Leota, who promises to relieve him of his troubles and "make me happier than I had ever been." Spurning her advances, he demands she complete her task and leave. That night, during a storm, Madame Leota discovers the ghosts are the crew of the "Pomona", whom Master Gracey had betrayed. She decided to make his home even more appealing to other ghosts instead of ridding it of the current ones. After this, Master Gracey prepares for the wedding, not knowing that in the attic, his former captain is preparing to become the infamous Hatbox Ghost.
