The ongoing Mystery of the Manse comes to a close as one of the big mysteries surrounding the mansion is revealed. A new ongoing story begins in this issue when the arrival of the 1,000th ghost triggers a catastrophe. The Haunted Mansion series is based on the favorite Disney attraction where 999 Happy Haunts make their home.

"Doom of the Diva" is written and drawn by Alice Price and Andy Price. It tells the story of Baronessa Elda, a famous opera singer who was eventually fired for her ego. She received an invitation to sing at Gracey Manor, which she graciously accepts. However, once she figures out her audience is made up entirely of ghosts, she runs out frightened and falls over a landing, her braid acting as a noose. Now she lives among them as the Viking Ghost, leading them all in song. This story is unique in referencing both the new black widow bride and the Haunted Mansion Holiday.

"Mystery of the Manse Pt. 6" is written by Dan Vado, drawn by Mike Moss, with lettering by David Hedgecock. In the final chapter, Master Gracey explains how since Leota was killed so quick mid-trance, her soul never realized she was dead. And now ghosts from all over the world heard her cries and came to Gracey Manor. The only living thing in the house was the maid Michelle, who decided to keep her master's treasure safe and continue playing maid. She even hired numerous other girls, one of whom inherits the house and fortune when Michelle dies to join the party. Master Gracey eventually learned how to leave his body so he could keep watch over the house. However, no one, not even the ghosts, dare to go to the attic where Emily lies.

"The Final Interview" is written by Dan Vado and illustrated by Drew Rausch. In the last chapter of the potential maid Sarah, her boyfriend Steve arrives at the mansion planning to stop her from killing herself. She arrives after him, and runs into Dick the groundskeeper (named Horace in previous stories) and his dog, Boney. He tells her that the party is not as fun as she expects, and that she must have something to live for. Meanwhile, Steve sees her outside and tries to reach her, only to be literally scared to death, making him spirit #1000. Upon this turn of events, the devil clock strikes 13 and the entire house and grounds are swallowed into a void, leaving only Sarah, the maid, Dick, and Boney. Dick's last line is "Well...I didn't see that coming," creating stares from the survivors.
