The king shifts left to right, revealing crimes (5)
I believe the answer is:
evils
'crimes' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for evils that I've seen before include "Lives (anag.)" , "transgressions" , "Sins and depravities" , "immoral actions" , "Iniquities" .)
