Doctor Who: The Ninth Doctor Adventures: Thirteen O'Clock (4.06)

The Doctor and Rose return once more to the Powell Estate, but now the Doctor has a dreadful suspicion about the malevolent power that keeps pulling them back. The estate is shrouded in a strange fog, most of the residents have vanished, and the sinister Mrs Crook guards the ominous Flat 13.

What's more, Saffron Windrose has arrived in search of the Doctor, because once he helped her face a nightmarish entity at a railway station called Underbridge... and it's happening again.
