【Secret Confessions (2025) Maid in Heaven Episode 42】

Up until now we've had two Black MirrorSeason 4 episode teasers,Secret Confessions (2025) Maid in Heaven Episode 42 and neither of them exactly look cheerful.

The third trailer looks even more grim, though.

On Wednesday, the official @blackmirror account shared a 1-minute teaser video for "Black Museum":

That episode is going to contain three stories in one, according to producer Annabel Jones -- and from the looks of the teaser and the equally creepy poster that was tweeted out on Tuesday, it's going to be one of Season 4's darker episodes.

It's sort of hard to tell exactly what's going on in the clip, but the story seems to revolve around a museum dedicated to past crimes -- and possibly an experience which allows people to relive those crimes in some way, à la Strange Days?

Either way, based on the final quote of the trailer ("But how long can happiness realistically last anyhow?") it's not going to be a cheerful one.
