Howls coming from compartments (4)
I believe the answer is:
bays
I believe this is a double definition.
'howls' is the first definition.
(I've seen this in another clue)
'compartments' is the second definition.
(I know this)
'coming from' acts as a link.
(Other definitions for bays that I've seen before include "Inlets; barks" , "Indentations of a shoreline" , "Laurel trees" .)
