And once, just because the sky was blue and the air was sweet, and it was so good to be alive, David lifted his bow and put it all into a rapturous paean of ringing exultation--that a sick man in a darkened chamber above the street lifted his head, drew in his breath, and took suddenly a new lease of life, David still again did not know.

All of which merely goes to prove that David had perhaps found his work and was doing it--although yet still again David did not know.
It was in the cemetery one afternoon that David came upon the Lady in Black.

She was on her knees putting flowers on a little mound before her.

She looked up as David approached.

For a moment she gazed wistfully at him; then as if impelled by a hidden force, she spoke.
"Little boy, who are you ?" "I'm David." "David! David who?
Do you live here?
I've seen you here before." "Oh, yes, I've been here quite a lot of times." Purposely the boy evaded the questions.
