Morse cop novel one writes in bars (8)
I believe the answer is:
composer
'one writes in bars' is the definition.
I can't tell whether this defines the answer.
'morse cop novel' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'morse'+'cop'='morsecop'
'morsecop' with letters rearranged gives 'COMPOSER'.
Can you help me to learn more?
(Other definitions for composer that I've seen before include "A sedative" , "one to make notes" , "A creator of music" , "One scoring" , "Mozart or Mendellsohn" .)
