Sharp little stick took out Mrs Sayers' eye. (3)
I believe the answer is:
peg
'sharp little stick' is the definition.
'peg' can be an answer for 'stick' (thesaurus). I am not sure about the 'sharp little' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for peg that I've seen before include "Limit" , "Hook" , "Kind of clip for fastening clothes to line" , "Short pin or bolt" , "Wooden pin, small marker" .)
