Big Finish Doctor Who/Recap/049 Master

In a dark old manor home, as a storm rages outside, friends have gathered to celebrate the birthday of Doctor John Smith, a disfigured but kind gentleman, who was found wandering the streets of their planet, Perfugium, with no memory of who he was or where he had come from.

But as the night continues, the occupants begin to notice something a bit...off, about the house. And when a mysterious, short scottish man arrives, who Mr Smith vaguely recognises, that's when things start to get really interesting.

Part of the "Villains Trilogy", leading up to Zagreus.

": Why, me sir? I'm ."
 * Laser-Guided Amnesia: Dr. Smith. It's not exactly a secret who he was.
 * Tomato in The Mirror: You know it's coming, but.
 * Or for the Doctor to discover that.
 * Wham! Line:  reveal at the end of episode 3.
