One with an uncanny ability to make money may be said to have the ____ touch (5)
I believe the answer is:
midas
(Other definitions for midas that I've seen before include "Mythical king who had the power to turn everything to gold" , "King of Phrygia who had a golden touch" , "One with a golden touch" , "Greek mythological king with money-making touch" , "Legendary king whose touch turned things to gold" .)
