Diarist takes a look, we hear (5)
I believe the answer is:
pepys
'diarist' is the definition.
(I know that Pepys is a diarist)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for pepys that I've seen before include "Famous English diarist" , "Journalist" , "Famous diary keeper" , "Samuel ---, C seventeen Admiralty secretary" , "Diary-writer" .)
