I think everyone in America has heard my message by now.
Even if they hear the message it won't mean a thing to them inside.
"They must have heard the message on the radio last night, when we did!"
But West had heard the message of his partner's pass.
Something had made one or both of them call his house and they heard the taped message.
They'd actually heard my message, and were spreading the word.
"Whoever was waiting for me must have heard the message."
The time might come, of course, when he would not consciously hear the message.
Yet it was still whispering, and now he could hear its message.
