So Sky voted, catastrophically, to reveal identity of person who wrote about criminal penalties etc. in Russia (10)
I believe the answer is:
dostoevsky
'identity of person who wrote about criminal penalties etc in russia' is the definition.
The definition suggests a singular noun which matches the answer.
'so sky voted catastrophically' is the wordplay.
'catastrophically' is an anagram indicator.
'so'+'sky'+'voted'='soskyvoted'
'soskyvoted' with letters rearranged gives 'DOSTOEVSKY'.
'to reveal' acts as a link.
Can you help me to learn more?
(Another definition for dostoevsky that I've seen is " Russian author".)
