Old master with stock found in Charlie's place? He'll have questions to answer (8)
I believe the answer is:
examinee
But I can't explain it at all! Could you help me understand?
(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" .)
