Crisis isn't about a deity (4)

I believe the answer is:

isis

'a deity' is the definition.
(Isis is an example)

'crisis isn't about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'ISIS' is hidden within 'crisis isnt'.

(Other definitions for isis that I've seen before include "Revered figure" , "Egypt. goddess" , "River Thames at Oxford" , "Old Egyptian fertility goddess" , "A dark blue flower" .)

I've seen this clue in The Daily Express.
