Doctor's notes showing Spooner's treatment given to immoral chef (8)
I believe the answer is:
casebook
'immoral chef' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'doctor's notes showing spooner's treatment' is the wordplay.
I cannot really see how this works, but
'notes' could be 'eb' and 'eb' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'given to' is the link.
Can you help me to learn more?
(Other definitions for casebook that I've seen before include "Medical records" , "compiled by doctor for famous consultant" , "Doctor's or lawyer's record" , "Record of work" , "Doctor's written record" .)
