Well, this is the one we've all been waiting for. These just-released synopses from Steven Moffat reveal a lot about the story arc for the rest of this season of Doctor Who. They verge on becoming spoilers, so if you're determined to remain completely in the dark about what's coming next then I'd suggest clicking away from this page right now.

Amongst other things, we find out more about the return of James Corden as Craig Owens, the mechanisms of fate by which our heroes come face to face with Hitler, and hints that the final episode will bring everyone back to that lake in Utah. Based on these descriptions, the episode I'm looking forward to most is the "impossible hotel", what sounds like a hellish version of Holiday Inn that prevents visitors from ever checking out. Moffat shines when writing the scarier episodes of Doctor Who and hopefully this won't be an exception.

And my favourite phrase from the whole thing? "A new and unfamiliar presence is wreaking havoc in Colchester." We ask Colchester-based readers to report back on whether this is true, or if it's just that new Sainsbury's they built last year.
