Nurse ____ Barton (5)
I believe the answer is:
clara
'nurse barton' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for clara that I've seen before include "-- Bow, silent film actress" , "Schumann" , "- Bow, US actress, the 'It Girl'" , "Home town of the Taoiseach" , "Woman" .)
