Moved sneakily (5)
I believe the answer is:
crept
'moved sneakily' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for crept that I've seen before include "was obsequious" , "Sneaked" , "Went stealthily or furtively" , "Moved slowly and carefully" , "acted in subservient way" .)
