Old master with stock found in Charlie's place? He'll have questions to answer (8)
I believe the answer is:
examinee
'old master with stock found in charlie's place? he'll have questions to answer' is the definition.
The definition suggests a singular noun which matches the answer.
'in charlie's place? he'll have questions to answer' is the wordplay.
I cannot really see how this works, but
'in' is present in the answer.
'questions' could be 'exam' (a set of questions) and 'exam' is located in the answer.
The remaining letters 'ee' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for examinee that I've seen before include "in France, one taking the Baccalaureat?" , "one facing Test" , "One being tested" , "One's tested" , "GCSE entrant" .)
