Lie about captured king meeting with agitator (9)
I believe the answer is:
firebrand
'agitator' is the definition.
(I've seen this before)
'lie about captured king meeting' is the wordplay.
I cannot quite understand how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is located in the answer.
'lie' could be 'fib' (fib is a kind of lie) and 'fib' is located in the remaining letters.
'captured' could be 'ran' (running is a kind of capturing) and 'ran' is found in the answer.
A single letter 'd' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'with' acts as a link.
Can you help me to learn more?
(Other definitions for firebrand that I've seen before include "Troublemaker" , "Rabble-rouser" , "Energetic person often fomenting trouble" , "Agitator" , "One who stirs up trouble" .)
