Novelist related incomplete tale, not right (7)
I believe the answer is:
tolstoy
'novelist' is the definition.
(I've seen this before)
'incomplete tale not right' is the wordplay.
'incomplete' becomes 'tol' (I can't explain this - if you can you should believe this answer much more).
'tale' becomes 'story' (synonyms).
'not' suggests deleting specific letters.
'right' becomes 'r' (abbreviation).
'story' with 'r' removed is 'stoy'.
'tol'+'stoy'='TOLSTOY'
'related' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tolstoy that I've seen before include "Lost toy of the Russian author" , "He wrote Anna Karenina" , "Russian writer, 1828-1910" , "Russian novelist" , "Great Russian author of 'War and Peace'" .)
