Lock keeper comes out of the rain (7)
I believe the answer is:
hairnet
'lock keeper' is the definition.
'hairnet' can be an answer for 'keeper' (I have seen 'keeper of locks' mean 'hairnet' so perhaps 'keeper' could also mean 'hairnet'). I'm not sure about the 'lock' bit.
'out of the rain' is the wordplay.
'out of' indicates an anagram.
'the'+'rain'='therain'
'therain' anagrammed gives 'HAIRNET'.
'comes' acts as a link.
Can you help me to learn more?
(Other definitions for hairnet that I've seen before include "protection overhead" , "Mesh worn over the head" , "Tonsorial restraint" , "Cover for head" , "It protects locks" .)
