"Fetzer tells me that you use ammonia for household purposes," said Stephen. "Where do you keep it?"
Ellen's eyes sought Fetzer's for confirmation.
"In the cupboard in the hall."
"Have you ever missed any?"
"Why, no!"
"Does any one but yourself go to the cupboard?"
"No"—then Ellen corrected herself. She still spoke straightforwardly and innocently. "Mrs. Lanfair got some there yesterday; she filled one of the engraved bottles from her bathroom; at least I think so."
"What makes you think so?"
Ellen flushed.
"Because I saw that a new bottle had been opened, and when I cleaned Mrs. Lanfair's bathroom I saw there was ammonia in her violet water bottle. I think she probably wanted to clean a chain or something."
