Inevitably, journalist’s letter found in home (5,4)
I believe the answer is:
needs must
'inevitably' is the definition.
(what must happen)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for needs must that I've seen before include "Perforce" , "Of necessity" , "'. . . . . . . . . when the devil drives'" , "unavoidable" , "It can't be helped" .)
