Disguised in Emerald Isle, a spy: Tees won't blab (2,4,3,6)
I believe the answer is:
my lips are sealed
'disguised in emerald isle a spy tees won't blab' is the definition.
I can't judge whether this defines the answer.
'disguised in emerald isle a spy tees won't blab' is the wordplay.
'emerald isle a spy' can be anagrammed to 'MY LIPS ARE SEALED'.
But, I am not clear how this is indicated.
Can you help me to learn more?
(Other definitions for my lips are sealed that I've seen before include "I'll keep mum" , "I can't say" , "I won't say a word" .)
