Diarist ____ Frank (4)
I believe the answer is:
anne
'diarist frank' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for anne that I've seen before include "Second or fourth wife of Henry VIII" , "Girl's name" , "One of Henry VIII's wives" , "She married Shakespeare" , "- - Hathaway, wife of Shakespeare" .)
