Touchy one? (5)
I believe the answer is:
midas
'touchy one?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for midas that I've seen before include "Everything he touched turned to gold" , "King of Phrygia who had a golden touch" , "I'm sad (anag) -- king of Phrygia" , "Greek mythological king with money-making touch" , "Legendary king who could turn everything to gold" .)
