Clueless, fumbling for light switch? (2,3,4)
I believe the answer is:
in the dark
I believe this clue is a double definition.
'clueless' is the first definition.
(I've seen this in another clue)
'fumbling for light switch?' is the second definition.
(in the dark without a light on)
(Other definitions for in the dark that I've seen before include "overnight" , "Ignorant, unaware" , "after sundown" , "without being told" , "Ill-informed" .)
