Dangled it before panel of peers but they couldn't come to an agreement (4,4)
I believe the answer is:
hung jury
'an agreement' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I can't see?
'dangled it before panel of peers but they couldn't' is the wordplay.
I cannot quite understand how this works, but
'dangled' could be 'hung' (I've seen this before) and 'hung' is found within the answer.
'panel' could be 'jury' (synonyms) and 'jury' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'come to' is the link.
Can you help me to learn more?
(Other definitions for hung jury that I've seen before include "Body of twelve unable to reach a verdict" , "Group undecided" , "Cause of a mistrial" .)
