“Yes, sir. Not only my son and my daughter have heard and seen strange things in it, but the maids have also had such experiences.”

“Such as what?”

“Hearing queer sounds. Once, there was a complete conversation carried on by voices that belonged to invisible people.”

“This is interesting only if confirmed by credible witnesses,” Hanley said.

“It interests me, anyway,” said Harbison. “I don’t believe in levitation and the passing of a human body through a locked door, but a haunted room always thrills me. Tell me some more about it.”

“I will,” said Henrietta. “For the last year or two, there have been times when voices were audible there. Not loud or entirely distinct,—but vaguely to be heard,—like the sound of a faraway speaker. My brother heard them,—he frequently told me so.”

“Well, not frequently, Henrietta,” said her mother, correcting her, “but two or three times.”

“Who else heard them?” asked Hanley, briefly.

“The servants,” Henrietta informed them. “One chambermaid was so frightened she left at once.”

“Oh, fiddlesticks!” cried Harbison. “This gets us nowhere! If they were really spirits it is absurd; and if, as I thought at first, they were human voices, heard through a secret passage or a hollow panel, it’s up to us to find the secret entrance.”
