Agree to get involved with Mrs Wordsworth’s home (8)
I believe the answer is:
grasmere
'wordsworth's home' is the definition.
(village home to William Wordsworth)
'agree to get involved with mrs' is the wordplay.
'to get involved with' is an anagram indicator.
'agree' mixed up with 'mrs' gives 'GRASMERE'.
(Other definitions for grasmere that I've seen before include "Wordsworth's Lake District home" , "Wordsworth dwelt" , "Wordsworth's village" , "De Quincey at home here" .)
