Knock knock, who's there? It's David Suchet!
The actor, who is famous for playing Detective Poirot in, well, Agatha Christie's Poirot, will be joining the tenth series of Doctor Who.
The details are shrouded in mystery at the moment, which has got us putting our detective hats on and coming up with theories, helped with the arrival of this teaser-y new image of Suchet in action.
We know that David Suchet's character is called the Landlord, so instantly we are reminded of the series five episode 'The Lodger'.
Could we see a return of the aliens that were hiding in James Corden's flat? Will James Corden himself return? Is the Landlord meant to be The Landlord with a capital T, making him a potential Time Lord? Should we just stop now?
We also know the episode is going to be written by Mike Barlett, who wrote the wildly successful Doctor Foster. This doesn't go any way to explaining who Suchet will be playing, but it gives us hope the episode will be a corker, whatever happens.
Doctor Who will be returning at Christmas for a special episode, then again for a full series in 2017. The series will be showrunner Steven Moffat's last, and new companion Pearl Mackie's first.
