Station escort guarding dramatist (7)
I believe the answer is:
ionesco
'dramatist' is the definition.
(I've seen this before)
'station escort guarding' is the wordplay.
'guarding' indicates the answer is hidden within the clue.
'IONESCO' can be found hidden inside 'station escort'.
(Other definitions for ionesco that I've seen before include "O so nice (anag) - playwright" , "Playwright associated with the theatre of the absurd" , "Eugene -, Fr. dramatist (Theatre of the Absurd)" , "Eugene -, Romanian-born French playwright" , "Romanian-born French dramatist" .)
