War and Peace creator possibly lost plaything (7)
I believe the answer is:
tolstoy
'war and peace creator' is the definition.
I can't tell whether this definition defines the answer.
'possibly lost plaything' is the wordplay.
'possibly' indicates an anagram.
'plaything' becomes 'toy' (synonyms).
'lost' with letters rearranged gives 'tols'.
'tols'+'toy'='TOLSTOY'
Can you help me to learn more?
(Other definitions for tolstoy that I've seen before include "Russian novelist" , "Great Russian author of 'War and Peace'" , "He wrote Anna Karenina" , "Writer of War and Peace, d.1910" , "Count Leo . . . . . . ., author of 'War and Peace'" .)
