Fireman who doesn't put fires out (6)
I believe the answer is:
stoker
'fireman' is the definition.
(someone who tends to a furnace)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for stoker that I've seen before include "Bram ...... created 'Dracula'" , "Worker who feeds a furnace" , "Dracula's creator -- furnace feeder" , "Irish author of Dracula, d. 1912" , "Fireman (on steam train)" .)
