Novelist who would keep the fire burning? (6)
I believe the answer is:
stoker
This clue is a double definition.
'novelist' is the first definition.
(Bram Stoker, author of Dracula)
'who would keep the fire burning?' is the second definition.
(someone stoking a fire)
(Other definitions for stoker that I've seen before include "Worker who feeds a furnace" , "who fed the flames?" , "who added fuel to the flames?" , "Bram ...... created 'Dracula'" , "One tending furnace" .)
