Meet the Landlord in Episode 4, Knock Knock
Written by Mike Bartlett and directed by Bill Anderson, the episode guest stars David Suchet as the Landlord.
Bill is moving in with some friends and they’ve found the perfect house – so what if it’s strangely cheap to rent, and the landlord is a little creepy?
The wind blows, the floorboards creak, and the Doctor thinks something is very wrong. What lurks in the strange tower at the heart of the building – and why can’t they find any way to enter it?
