In the fourth Christmas special saw the Doctor face not only Cybermen but also himself, in a snowbound Victorian London.
Was this new Who -- played by David Morrissey -- a future regeneration or a version he doesn't remember?
Either way, they have to team up to solve a murder mystery, foil a Cyberplot and stop the evil Miss Hartigan.
The resulting adventure isn't the best seasonal Doc spot -- and the climax is rather ludicrous -- but it offers lots of laughs and a few thrills.
This DVD also offers Doctor Who at the Proms, a ./... concert of Who music with clips from all four series.
