The BBC has announced that Ingrid Oliver will reprise her role as UNIT scientist Osgood in the upcoming ninth season of Doctor Who.
Oliver's two-part episode is currently filming in Cardiff, with the ninth season premiering on BBC One in the autumn.
The show's lead writer and Executive Producer, Steven Moffat, said: "Osgood is back, fresh from her recent murder at the end of last series. We recently confirmed that Osgood was definitely dead and not returning - but in a show about time travel, anything can happen.
"The brilliant Ingrid Oliver is back in action. This time, though, can the Doctor trust his number one fan?"
Oliver said: "As every actor who's worked on Doctor Who will tell you, there's always the secret hope you'll get the call asking you to come back.
"To actually receive that call is both unexpected and brilliant. The word 'honour' gets banded about a lot, but it really is: it's an honour. Especially because I was so sure Osgood was a goner after the last series!"
