Woman’s husband caught in fire, perhaps (7)
I believe the answer is:
heather
'woman's' is the definition.
(woman's name)
'husband caught in fire perhaps' is the wordplay.
'husband' becomes 'h'.
'caught in' indicates putting letters inside.
'fire perhaps' becomes 'heater' (a fire provides heat).
'h' going into 'heater' is 'HEATHER'.
(Other definitions for heather that I've seen before include "Small evergreen plant with purple flowers from highlands" , "Girl's name - ling" , "Another term for ling" , "Moorland flora" , "grows wild" .)
