She has to live in with Lois, maybe (6)
I believe the answer is:
isobel
'she' is the definition.
'to live in with lois maybe' is the wordplay.
I cannot quite understand how this works, but
'live' could be 'be' (synonyms) and 'be' is present in the answer.
an anagram of 'lois' is 'isol' which is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
'has' acts as a link.
Can you help me to learn more?
(Another definition for isobel that I've seen is " Lobs, i.e. into a girl's name".)
