Gee! CIA is lost in the glacial times (3,3)
I believe the answer is:
ice age
'the glacial times' is the definition.
The definition and answer can be both related to time as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'gee cia is lost' is the wordplay.
'is lost' is an anagram indicator.
'gee'+'cia'='geecia'
'geecia' anagrammed gives 'ICE AGE'.
'in' is the link.
Can you help me to learn more?
(Other definitions for ice age that I've seen before include "When glaciers covered a large part of the earth's surface" , "Period of extreme cold" , "Pleistocene era" , "when it gets very cold" , "Earth's period of glaciers - brrr" .)
