Close relations in The Guards perhaps (9)
I believe the answer is:
daughters
'close relations' is the definition.
'daughters' can be an answer for 'relations' (daughter is a kind of relation). I am not sure about the 'close' bit.
'the guards perhaps' is the wordplay.
'perhaps' indicates an anagram.
'the'+'guards'='theguards'
'theguards' with letters rearranged gives 'DAUGHTERS'.
'in' is the link.
Can you help me to learn more?
(Other definitions for daughters that I've seen before include "The guards turn out to be relatives" , "Female offspring" .)
