"Nuns don't whistle, and the common is hundreds of yards away. And no boy on the common knows the bird music from 'Siegfried'? Listen, Louise, listen! There it goes, note for note. Francis is singing well to-day."
"Francis!"
"Look, look, you can see him! Now are you convinced?"
And the wonder in Louise's face passed into a look of real fear, and she said:
"Let us go away."
"But why won't you listen to Francis? None of my birds sings as he does. Let me tell you, Louise—"
But Louise's step hastened.
"Stop! Don't you hear the Sword motive? That is Aloysius."
Louise stopped for a moment, and, true enough, there was the Sword motive whistled from the branches of a sycamore. And Louise began to doubt her own sanity.
"You do hear him, I can see you do."
