The Christmas Special is just one week and day away but Doctor Who really knows how to tease its fans with promos, previews, intros and prequels. We were treated to the first prequel to the Christmas Special last month with “The Great Detective”, now Vastra, Jenny and Strax’s exploits continue with “Vastra Investigates” where they make do without the Doctor’s help, and teach Victorians a lesson in tolerance.
