Doctor Who Series 10 Episode 4: What to expect
The fourth episode of Doctor Who Series 10 is called ‘Knock Knock’ and, once again, stars Peter Capaldi and Pearl Mackie as the Doctor and his assistant, Bill, respectively.
In this episode, we’ll also get to see David Suchet play a sinister landlord. Suchet is famous for portraying Agatha Christie’s legendary detective Hercule Poirot in countless TV adaptations, so he’s sure to deliver a sufficiently interesting performance.
Here’s the BBC’s episode synopsis:
“Why do floorboards creak? When a sinister landlord shows Bill and her friends the perfect houseshare, they have no idea what lies ahead… knock knock, who’s there?”
