Warning of endless damage facing Netflix addict? (9)
I believe the answer is:
harbinger
'warning' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for harbinger that I've seen before include "sign of things to come" , "It indicates the future" , "Early sign" , "One announcing approach" , "One giving advance warning" .)
