Like the French, he's free from deceit (3)
I believe the answer is:
les
'like the french he's free from deceit' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for les that I've seen before include "-- Dawson, English comic" , "Boy's name (abbr)" , "French article; name" , "- Dawson, Br. comedian" , "-- Miserables, musical" .)
