Meek, thin fiction rewritten at the very last moment (2,3,4,2,4)
I believe the answer is:
in the nick of time
'at the very last moment' is the definition.
I can't judge whether this definition defines the answer.
'meek thin fiction rewritten' is the wordplay.
'rewritten' indicates an anagram.
'meek'+'thin'+'fiction'='meekthinfiction'
'meekthinfiction' with letters rearranged gives 'IN THE NICK OF TIME'.
Can you help me to learn more?
(Other definitions for in the nick of time that I've seen before include "at the critical moment" , "almost, but not quite, too late" , "not a moment too soon" , "at last possible moment" , "at the eleventh hour" .)
