YOu are also assuming that he will think you have only one source... All you have to tell your H is
"A LOT of people know a LOT more about what you're doing than YOU THINK... We are NOT stupid..."
That's an incredibly vague statement that should intimidate him quite a bit...
AGREE!! Maybe even an "I frankly was amazed by how many people came out of the woodwork, some of whom I didn't even know. There are a lot of people concerned about you, you know."
You can also let slip a "he" when your source is really a "she," or a "I heard" when you really SAW, etc. -- to throw them off track. I hinted that my intel was visual, to throw my wife off track to the voice-recorder.
