Consumed in fire at Enniskillen (5)
I believe the answer is:
eaten
'consumed' is the definition.
('eaten' can be similar in meaning to 'consumed')
'in fire at enniskillen' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EATEN' can be found hidden inside 'fire at enniskillen'.
(Other definitions for eaten that I've seen before include "dined" , "corroded" , "Scoffed" , "Upset" , "What's taken in" .)
