Opening the door, he saw Mr. Whitney standing before him, while in the background servants were running in different directions, wringing their bands and moaning and crying hysterically.

"Mr. Scott," said the attorney, in tones trembling with excitement, "come to the tower-room at once. Mr. Mainwaring has been murdered!"

"Mr. Mainwaring murdered!" he exclaimed, reeling for an instant as if from a blow. "Great heavens! it cannot be possible!"
