Murderer secures suitable chef for explorer (7,4)
I believe the answer is:
captain cook
'explorer' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'murderer secures suitable chef' is the wordplay.
'murderer' becomes 'cain' (Biblical figure).
'secures' indicates putting letters inside.
'suitable' becomes 'apt' (apt means appropriate or fitting).
'chef' becomes 'cook' (both can mean someone who cooks).
'cain' enclosing 'apt' is 'captain'.
'captain'+'cook'='CAPTAIN COOK'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for captain cook that I've seen before include "18th century navigator and explorer" , "English explorer, killed in Hawaii" , "New Zealand's charter" .)
