Maids running from mythical king (5)
I believe the answer is:
midas
'mythical king' is the definition.
(I've seen this in another clue)
'maids running' is the wordplay.
'running' indicates an anagram (the letters run around to different places).
'maids' anagrammed gives 'MIDAS'.
'from' is the link.
(Other definitions for midas that I've seen before include "Mythical king with golden touch" , "Phrygian king" , "His touch made gold" , "King who turned what he touched to gold" , "I'm sad (anag) -- king of Phrygia" .)
