There's 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.
The Lodger is due to air June 12, 6.45 pm
