Hiding place revealer, maybe (6)
I believe the answer is:
sneeze
'hiding place revealer maybe' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sneeze that I've seen before include "Act of sternutation" , "Violent, involuntary expulsion of breath" , "Minor bodily explosion" , "symptom of flu" , "Nasal eruption from common cold" .)
