"Breathing Lessons” author Tyler (4)
I believe the answer is:
anne
'breathing lessons author tyler' 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" , "Henry's second" , "Shakespeare's wife's name" , "Boleyn or Hathaway, say" , "Henry VIII's fourth wife" .)
