Doctor Who 5/11 The Lodger

Theres a house on Aickman road, and a staircase that people go up, but never down, as the time-travelling drama continues.

To solve the mystery of the man upstairs, the Doctor faces his greatest challenge yet – he must pass himself off as a perfectly normal human being, and share a flat with Craig Owens.

Update 29/5/10

was thought this episode was going to be renamed to dont go up the stairs but the bbc changed their mind
