A sequel would be an episode of what happened between Miss Sophie and the butler in bed after dinner.

A prequel would be the life and times of her now dead guests.

Don't get me wrong, a sequel would be cool too! Perhaps we could get a glimpse into Miss Sophie's legacy after she passes away, and how her butler needs to contend with her snarky relatives who wants to get rid of that infernal tiger on the floor, only to replace it with an even larger bear pelt.
