The first episode of the 12th season of Doctor Who has a spy-vibe with the two part “Spyfall!” It features comedian Stephen Fry as “C” and the return of one of the Doctor’s old enemies!!!
I loved it.
But the return of an old enemy is DEFINITELY a spoiler, given his reveal is the cliffhanger of part 1
Ditto- Lenny Henry for M! Starting it here and now!
