Plot to succeed — leave carrying large bed cover (9,5)
I believe the answer is:
patchwork quilt
'cover' is the definition.
(I've seen this before)
'plot to succeed leave carrying large bed' is the wordplay.
I cannot really see how this works, but
'plot' could be 'patch' (synonyms) and 'patch' is found within the answer.
'succeed' could be 'work' (work can mean to succeed at a purpose) and 'work' is found within the answer.
'large' could be 'l' (eg in clothes sizes) and 'l' is found within the answer.
'leave' could be 'quit' (synonyms) and 'quit' is found within the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for patchwork quilt that I've seen is " cover".)
