Good people secure home for the king (9)
I believe the answer is:
graceland
'home for the king' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'good people secure' is the wordplay.
'good' becomes 'g' (abbreviation).
'people' becomes 'race' (people can mean a national group or race).
'secure' becomes 'land' (land can mean to secure or obtain).
'g'+'race'+'land'='GRACELAND'
Can you help me to learn more?
(Other definitions for graceland that I've seen before include "Elvis Presley's home" , "Elvis shrine" , "Paul Simon album" , "The King's residence" .)
