Holder of valuable papers to conclude trial quickly (8,4)
I believe the answer is:
dispatch case
'holder of valuable papers' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'conclude trial quickly' is the wordplay.
I cannot really see how this works, but
'trial' could be 'case' (as in a legal case) and 'case' is present in the answer.
The remaining letters 'dispatch' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Another definition for dispatch case that I've seen is " documents found here".)
