Le Fanu? Who scandalised the educational establishment? (8)
I believe the answer is:
sheridan
I believe this clue is a double definition.
'le fanu?' is the first definition.
(I've seen this before)
'who scandalised the educational establishment?' is the second definition.
(I've seen this before)
(Other definitions for sheridan that I've seen before include "The Rivals author" , "Who scandalised the educational establishment?" , "Irish playwright and politician, d. 1816" , "Irish playwright (The Rivals)" , "Irish writer" .)
