Without any attempt at concealment (7)
I believe the answer is:
blatant
'without any attempt at concealment' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for blatant that I've seen before include "Very obvious and without shame" , "Brazen, flagrant" , "Totally obvious" , "Without any attempt at concealment" , "Overt and shameless" .)
