Evil spirit or devil (5)

I believe the answer is:

demon

This clue is a double definition.

'evil spirit' is the first definition.
(I know that demon are evil)

'devil' is the second definition.
(I know that devil can be written as demon)

(Other definitions for demon that I've seen before include "Ghoul" , "ace" , "Evildoer" , "Genius" , "Familiar" .)

I've seen this clue in The Times.
