26x05 Ghost Light Part One [2nd watch]
It's quite hard to think of a classic Who serial that's very like Listen, so this is the best I could come up with: the Doctor taking his companion to a mysterious and nigh-unfathomable thing from their past in a dark, creepy and complex tale.
It also means that, for the second week in a row, my tie-in four-parter is less than four parts. Ho hum.
