Grave danger (5)

I believe the answer is:

peril

'grave danger' is the definition.
(peril means great danger)

This is all the clue.

(Other definitions for peril that I've seen before include "Danger, jeopardy" , "Danger, hazard" , "Quest" , "risk" , "Hazardous situation" .)

I've seen this clue in the Universal, The Daily Mail, the Family Time, The Mirror and the LA Times.
