Beaming traitor keeps lead from DI Fleming? (7)
I believe the answer is:
radiant
'beaming' is the definition.
(synonyms)
'traitor keeps lead from di fleming?' is the wordplay.
'traitor' becomes 'rat' (I've seen this before).
'keeps' indicates putting letters inside.
'lead from di fleming?' becomes 'dian' (I can't justify this - if you can you should believe this answer much more).
'rat' going around 'dian' is 'RADIANT'.
Can you help me to learn more?
(Other definitions for radiant that I've seen before include "Brilliant" , "Brightly glowing" , "Shining brightly, being at nadir" , "Straight line" , "Beautiful" .)
