Retreat from a creamy tug? (5,5)
I believe the answer is:
ivory tower
'retreat' is the definition.
(I've seen this in another clue)
'a creamy tug?' is the wordplay.
'a creamy' becomes 'ivory' (I've seen this before).
'tug?' becomes 'tower' (something which tugs or tows).
'ivory'+'tower'='IVORY TOWER'
'from' is the link.
(Other definitions for ivory tower that I've seen before include "Academia (seen as secluded)" , "Seclusion from ordinary life" , "academic position" , "State of seclusion from worldly realities" .)
