With just under a week to go before the big day, the official Doctor Who website has shared this gem with us: Vastra Investigates, a prelude to the big event of The Snowmen Christmas episode.
Starring Neve McIntosh as Madame Vastra, Catrin Stewart as Jenny Flint and Dan Starkey as General Strax, this short reveals some backstory to Vastra’s presence in Victorian London, plays off Steven Moffat’s other big show Sherlock and leads into next weeks Christmas special.
Note that there is no Matt Smith, although the Doctor is mentioned.
Once you’ve watched this you should just manage to last until Christmas Day, when The Snowmen airs on BBC One at 5.15pm. Our American readers can tune into BBC America and catch the episode at the usual Doctor Who time of 9/8c a few hours later!
