3 writer? Yes, working through pages (5)
I believe the answer is:
pepys
'3 writer?' is the definition.
'pepys' can be an answer for 'writer?' (I've seen this before). I'm not certain of the '3' bit.
'yes working through pages' is the wordplay.
I cannot really see how this works, but
'yes' could be 'y' and 'y' is found in the answer.
'pages' could be 'p' and 'p' is located in the answer.
The remaining letters 'eps' 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 pepys that I've seen before include "Samuel ---, C seventeen Admiralty secretary" , "Journalist" , "Samuel -, English diarist" , "London diarist" , "Renowned diarist" .)
