As a mountain track may be, blustery and indirect (5)
I believe the answer is:
windy
This clue is a triple definition!
'as a mountain track may be' is the first definition.
(as in a track that winds around a mountain)
'blustery' is the second definition.
(thesaurus)
'and' is a link.
'indirect' is the third definition.
(winding around)
(Other definitions for windy that I've seen before include "Gusty" , "far from calm" , "Timid - tempestuous" , "Frightened - not still" , "Chicago, the _____ City" .)
