"So you know about it, you've had news of it."

"Yes, madam. I know what happened, including the tea that was served. And tell me—did your mistress die?"

"Yes, sir. She's gone to a better place."

"And what happened? Was she murdered or did she die of fright?"

"What murder? What fright?" she said with a mocking expression. "You're not in the know after all. She ate something that disagreed with her that night and it harmed her. She had a fainting fit that lasted till dawn."

This one, I thought, knows nothing about the incident with the piano and the poison or doesn't want to make me think she does. Afterwards I said in a loud voice:

"So she died of food poisoning?"

"Yes, sir. I warned her not to eat those shellfish, but she took no notice of me."

"Shellfish, eh?" I said incredulously. "I know what really happened."

"Don't you believe me?"
