Site of intrigue (4)
I believe the answer is:
plot
I believe this clue is a double definition.
'site' is the first definition.
(thesaurus)
'intrigue' is the second definition.
(I know that intrigue is a kind of plot)
'of' acts as a link.
(Other definitions for plot that I've seen before include "Conspiracy, secret plan" , "Scheme or small piece of land" , "garden area" , "Area of ground; storyline" , "Design" .)
