Fire tender Gothic writer (6)
I believe the answer is:
stoker
This clue might be a double definition.
'fire tender' is the first definition.
(I've seen this in another clue)
'gothic writer' is the second definition.
'stoker' can be an answer for 'writer' (I've seen this before). I'm not certain of the 'gothic' bit.
Can you help me to learn more?
(Other definitions for stoker that I've seen before include "piling on the heat?" , "who added fuel to the flames?" , "Worker who feeds a furnace" , "Furnace filler" , "Furnace man" .)
