Did get led astray by a cheat! (6)
I believe the answer is:
diddle
'a cheat' is the definition.
(I've seen this before)
'did get led astray' is the wordplay.
'get' says to put letters next to each other.
'astray' indicates anagramming the letters.
'led' is an anagram of 'dle'.
'did'+'dle'='DIDDLE'
'by' acts as a 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" .)
