Mole responsible for decapitation of emperor? (6)
I believe the answer is:
adrian
This could be a double definition.
'mole' is the first definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
'decapitation of emperor?' is the second definition.
The definition suggests a singular noun which matches the answer.
'responsible for' acts as a link.
Can you help me to learn more?
(Other definitions for adrian that I've seen before include "Name of six Popes" , "Boy's name" , "The first and only English Pope" , "Man's name" , "Name of Roman emperor and only English pope" .)
