Bother lurking in the shadows (3)
I believe the answer is:
ado
'bother' is the definition.
(both can mean fuss or commotion)
'lurking in the shadows' is the wordplay.
'ADO' is hidden within the letters.
However, I'm unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for ado that I've seen before include "Goings-on" , "Fuss, bother" , "stir" , "Busy activity, trouble" , "puff ball!" .)
