Where you can find Victoria's Secret (11)
I believe the answer is:
underground
'secret' is the definition.
(I know that secret can be written as underground)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for underground that I've seen before include "Travel on this" , "In hiding" , "Hidden away" , "Transport system" , "Subterranean" .)
