Devil's Advocate: After Scully's recovery post-One Breath, Mulder & Scully pose as newlyweds on a Mystery-Solving cruise to catch a serial killer.
Sanctuary: Escaped prisoners come across Maggie Scully's house where Mulder is recuperating with the Scully family after their cruise adventure.
Not to be confused with another story of the same name, these stories feature a Season 2 Mulder and Scully, posing as a married couple on a cruise ship. I had a bit of a cruise ship binge lately, and there's still more to come...
The second fic features the whole Scully family in peril, as Scully takes Mulder there to recover after the first story.
