I believe the answer is:

attic

I'm a little stuck... Click here to teach me more about this clue!

'top story' is the definition.
(I've seen this in another clue)

I cannot understand how the rest of the clue works.

(Other definitions for attic that I've seen before include "Ancient Greek; loft" , "where high-ups are found?" , "Loft room" , "Room inside a building's roof space" , "Top chamber" .)

I've seen this clue in The Times and The Sun.
