Did get led astray by a cheat! (6)
I believe the answer is:
diddle
'a cheat' is the definition.
(I've seen this in another clue)
'did get led astray' is the wordplay.
'get' is a charade indicator (letters next to each other).
'astray' indicates anagramming the letters.
'led' with letters rearranged gives 'dle'.
'did'+'dle'='DIDDLE'
'by' is the link.
(Other definitions for diddle that I've seen before include "Slang for cheat or swindle - nearly fiddle" , "Fleece" , "Slangily cheat or swindle" , "Con - do - lidded (anag)" , "Did, and led out to cheat" .)
