King of money-makers? (5)
I believe the answer is:
midas
This clue might be a double definition.
'king' is the first definition.
(mythical king)
'of money-makers?' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for midas that I've seen before include "King of Phrygia who had a golden touch" , "Phrygian king" , "Legendary king whose touch turned anything to gold" , "Mythical king who had the power to turn everything to gold" , "Golden-touch king" .)
