Rosina Nunn

In the Harley Quin short story The World's End, Rosina Nunn is an English actress who is travelling in  Corsica with her husband Henry Judd and her theatre producer Mr Vyse. Mr Satterthwaite, out on an excursion in the company of The Duchess of Leith and the artist Naomi Carlton Smith, meets Rosina when they are forced to seek shelter from the rain at the remote hilltop village of Coti Chiaveeri.

Mr Satterthwaite was pleased to meet her. He considered her one of England's greatest emotional actresses, someone with a talent for bringing out the finer shades of meaning. She was "an intellectual actress, one who comprehended and got inside the soul of her part". The encounter is, however, not a happy one for Naomi because her fiance, the playwright Alec Gerard had been convicted and jailed for stealing an opal from Rosina about a year earlier and was still in jail at the time of the events in the story.
