“Ha! It is the answer!” He tore it open, glanced his eyes over it, and crumpled it into his pocket. “That’s all right,” said he.

“Have you found out anything?”

“I have found out everything!”

“What!” Lestrade stared at him in amazement. “You are joking.”

“I was never more serious in my life. A shocking crime has been committed, and I think I have now laid bare every detail of it.”

“And the criminal?”

Holmes scribbled a few words upon the back of one of his visiting cards and threw it over to Lestrade.
