Cunning scheme making you gasp (6)
I believe the answer is:
wheeze
I believe this clue is a double definition.
'cunning scheme' is the first definition.
(a wheeze is a deceptive plan)
'gasp' is the second definition.
(I've seen this before)
'making you' is the link.
(Other definitions for wheeze that I've seen before include "To make husky sound when breathing" , "Struggle for breath - cunning plan" , "Clever trick or scheme" , "Breathe noisily; clever dodge" , "Joke; cunning plan" .)
