I believe the answer is:
paris
'helen's abductor' is the definition.

This is all the clue.
(Other definitions for paris that I've seen before include "English chronicler" , "foreign city" , "'''I love ... in the springtime'' (Cole Porter) (5)'" , "City where one may see the Mona Lisa" , "An American in - -" .)
