The writer-editor-raconteur has long hinted that he'd be writing an episode of Doctor Who. Now, via Twitter, Gaiman proves to us that he's actually done it.

His fingers may carefully obscure the script's title, but Gaiman — sitting with Blackadder creator Richard Curtis (who wrote the June 5 Who episode, "Vincent and the Doctor") and Doctor Who's executive producer Steven Moffat — can strike one item off what must be a Sisyphean to-do list. According to Gaiman, the as-yet untitled episode will air in the beginning of the next season.
