Showed around a vice den (7)
I believe the answer is:
evinced
'showed' is the definition.
('evince' can be a synonym of 'show')
'around a vice den' is the wordplay.
'around' indicates anagramming the letters.
'vice'+'den'='viceden'
'viceden' anagrammed gives 'EVINCED'.
(Other definitions for evinced that I've seen before include "Demonstrated" , "revealed" , "Clearly showed" , "Made evident" , "On display" .)
