Detective receiving cut, having secured second data storage item (4)
I believe the answer is:
disc
'storage item' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'detective receiving cut having secured second data' is the wordplay.
I cannot quite see how this works, but
'detective' could be 'di' (Detective Inspector abbreviation) and 'di' is found in the answer.
'second' could be 's' (common abbreviation) and 's' is found in the answer.
A single letter 'c' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for disc that I've seen before include "Circular flat structure in the spine" , "Gramophone record" , "Compact ---; slipped ---" , "jockey may be after" , "Circle" .)
