Queen once taken in by judge hides here, perhaps (7)
I believe the answer is:
tannery
'hides here perhaps' is the definition.
(where animal hides may be tanned)
'queen once taken in by judge' is the wordplay.
'queen once' becomes 'anne' (Queen Anne, 18th-century queen).
'taken in by' means one lot of letters goes inside another.
'judge' becomes 'try' (as in trialling a defendant).
'anne' placed into 'try' is 'TANNERY'.
(Other definitions for tannery that I've seen before include "Leather-processing plant" , "Rather like sun lamp, arguably" , "Place where leather is made" , "Building involved in making leather" , "leather shop" .)
