Writer of verse protests in odd places (4)
I believe the answer is:
poet
'writer of verse' is the definition.
(I've seen this before)
'protests in odd places' is the wordplay.
'in odd places' indicates alternate letters (only odd-numbered letters).
The alternate letters of 'protests' are 'POET'.
(Other definitions for poet that I've seen before include "Maker of verses" , "Burns was one" , "Eg, Keats or Auden" , "Writer in verse form" , "author" .)
