Watch The 'Doctor Who' Christmas Special Prequel 'Vastra Investigates'

"Heartbreak is a burden to us all, pity the man with two."

Let's see where Madame Vastra, her wife Jenny and "the Turkish fellow" Strax are prior to the snowy terror of this year's "Doctor Who" Christmas Special, "The Snowmen." Steven Moffat wrote this nicely-crafted little number that illuminates a sweet bit of personality for the reptilian detective, her human companion, and that dude who looks like a melted gingerbread man combined with a turtle.

"The Snowmen" airs Dcember 25 at 9pm ET on BBC America.
