Ooo... I knew that this back run on season four was good and so it proves here with another double episode story, one that introduces a seminal Nu-Who character and is more of the chilling horror that Steven Moffat has become synonymous with during his writing only days.
Responding to a message that appears on his physic paper, the Doctor (David Tennant) and Donna (Catherine Tate) head to the largest library in history, a whole planet dedicated to the preservation of books. Though eerily uninhabited, the Doctor discovers a security camera that seems linked to a little girl (Eve Newton) apparently living in 21st century Britain. Then they meet an archaeological team led by the enigmatic River Song (Alex Kingston) who appears to know the Doctor already, though he doesn't know her.
Moffat's penchant for horror comes out again here with the Vashta Nerada, microscopic creatures that will strip the flesh from a person in seconds. But there's also the more esoteric horror of the concept of echoes of dead people being trapped in their mental communicators - already dead, but still trying to make sense of their experience as the signal degrades. The image of the animated space suit, with only a skull inside the helmet repeating "who turned out the lights" as he chases down the others is a memorable one.
The cast of this episode is really strong, even down to tiny cameos from Sarah Niles and Josh Dallas. The archaeological team consists of several recognisable faces, from O-T Fagbenle, Talulah Riley, Harry 'Ray Bloody Purchase' Peacock and, completing the League of Gentlemen collection, Steve Pemberton. It's the first appearance of Alex Kingston's River Song though, that is the key one, as she would feature regularly from here on out during Moffat's time as show runner - which was announced just as this episode was going to air.
Two-part episodes can only really be judged at the conclusion of the second episode, but this is such an inventive start, jam packed with ideas, that it stands as one of Nu-Who's best episodes so far.
