Smart one from Stirling tracks fraud (9)
I believe the answer is:
chicanery
'fraud' is the definition.
(thesaurus)
'smart one from stirling tracks' is the wordplay.
'smart' becomes 'chic' (both can mean stylish).
'one' becomes 'an' (an apple is one apple).
'from' becomes 'e' (I've seen this in other clues).
'stirling tracks' becomes 'ry' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'chic'+'an'+'e'+'ry'='CHICANERY'
Can you help me to learn more?
(Other definitions for chicanery that I've seen before include "jiggery-pokery" , "Trickery used to gain advantage, duplicity" , "dishonest practices" , "deceptive" , "Sharp practice" .)
