Rural cottage is this writer's bolthole? (6)
I believe the answer is:
alcott
'this writer's bolthole?' is the definition.
'alcott' can be an answer for 'writer's' (I've seen this before). I'm not certain of the rest of the definition.
'rural cottage' is the wordplay.
'ALCOTT' is hidden within the letters.
But, I'm unsure how the hidden word is indicated.
'is' acts as a link.
(Other definitions for alcott that I've seen before include "Louisa, a writer" , "Author of Little Women, d. 1888" , "'Louisa May ..., author of Little Women (6)'" , "Novelist" , "Louisa May . . . . . . wrote 'Little Women'" .)
