John discovers that his presence has already been made known to the Moor.
He is expected to come forward.

Under the circumstances, the young man is in no condition for delay.

That song, that heavenly voice, has gone straight to his heart, and he longs to look upon the face of the sweet singer.
So he advances, not slowly and with any show of dignity, but in the eager way that does credit to his heart.
He sees a figure in black, seated near the old Moor, and instantly his eyes are glued upon that face.
Then his heart tells him he now looks upon the face of the mother who has been lost to him so long.
Does she know?
has she received his note, or is her presence here simply at the desire of her friend, the old Moor?
She does not show any intense excitement as he approaches, and this tends to make him believe she has been kept in ignorance of the truth.
The Mohammedan doctor and his lovely daughter watch his advance with deep interest, for they are human, and take pleasure in a good deed done.

The Koran commends it just as thoroughly as does our Bible.

At the same time slaves are in waiting near by, armed with deadly cimeters, and should it prove that John has deceived them, that the Sister does not greet him with love, but fear, because he bears the name of Craig, a signal from Ben Taleb will be the signing of his death warrant.
John fastens his eyes hungrily upon the face he now sees.
