Go quietly, as a burglar may do (5)
I believe the answer is:
steal
'go quietly' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for steal that I've seen before include "Purloin" , "bargain?" , "Creep" , "Thieve" , "Nick" .)
