In this way, wrongly shut (4)

I believe the answer is:

thus

'in this way' is the definition.
('thus' can be a synonym of 'in this way')

'wrongly shut' is the wordplay.
'wrongly' indicates an anagram (I've seen this in other clues).
'shut' with letters rearranged gives 'THUS'.

(Other definitions for thus that I've seen before include "an original Christmas gift" , "as indicated" , "'So, therefore (4)'" , "It follows" , "Shut (anag.)" .)

I've seen this clue in the Evening Standard.
