Sleight of hand; deception (8)
I believe the answer is:
trickery
This clue is a double definition.
'sleight of hand' is the first definition.
(thesaurus)
'deception' is the second definition.
(I know that trickery is a type of deception)
(Other definitions for trickery that I've seen before include "Legerdemain" , "Hocus-pocus" , "cheating" , "Practice of deception" , "Smoke and mirrors?" .)
