Beaver's den (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
lodge
'beaver's den' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for lodge that I've seen before include "small house alongside park" , "See 2" , "Settle" , "Small gatehouse" , "Stay (somewhere) temporarily" .)
