Scoundrels; stilettos, say (5)
I believe the answer is:
heels
I believe this is a double definition.
'scoundrels' is the first definition.
(heel is a kind of scoundrel)
'stilettos say' is the second definition.
(I know that stiletto is a type of heels)
(Other definitions for heels that I've seen before include "Foot parts" , "despicable people" , "Parts of shoes" , "Take to them and run away" , "Wedges" .)
