It’s Halloween today but it looks like the real scares are on the way tomorrow, as this year’s Doctor Who finale will officially get underway in Dark Water.

To prepare us for what lies in store, the BBC has released the episode’s introduction in which Peter Capaldi and Steven Moffat offer their usual array of cryptically tantalising hints.

“One of the questions that faces all of us is, ‘What happens when we die?’” Steven Moffat teases. “I hope it’s a lot nicer than this…”

Check out the introduction below and we’ve got plenty more where that came from! Check out our Series Finale section for trailers, pictures plus our exclusive interview with the finale’s director, Rachel Talalay. The Series 8 conclusion begins tomorrow night on BBC One at 8:15pm.
