It sent a thrill through him.

He ran to the door, and whined, but Joan was deep in slumber and did not hear him.

Once more he heard the cry, and only once.

He crouched down near the door.
Joan found him there, still watchful, still listening, when she awoke in the early morning.

She came to open the door for him, and in a moment he was gone.
