Opening the door with a sudden jerk, he plunged into the hall. A shadow was just disappearing from the opposite doorway. With a shout to me to light up, he leaped across the hall into the dining-room. The next minute I heard a cry, then a low gurgle; then the match I had hastily struck flared up, and I beheld the detective holding down the butler and looking eagerly towards me for the expected light.

The man in the hall was by this time at my side, and between us we soon had three jets lit, illuminating two white faces: Sweetwater's pale with triumph, Hewson's blue-white from fear.

"Murderer! Poisoner of your benefactor and friend, I have you at last!" cried the struggling detective, watching how each terrible word he hurled blanched to a greater and greater degree the face he held pressed back for our inspection.

"You could see without faltering your master's sons, the boys you have dandled on your knee, fall one after the other under the shadow of public suspicion. Now we will see if you can show as much heroism on your own account. You are the man who drugged Mr. Gillespie's wine; and if the officer here will take you in charge for an hour or so, I will go down and procure a warrant for your arrest."

The attack was so sudden, and Sweetwater's manner one of such complete conviction, that the old man succumbed to it without a struggle.

"Mercy!" he moaned. "I was old—tired of work—a little home—a little freedom in my old age—a—a——"

I fled from the room. It seemed as if the walls must cave in upon us. For this, for this!

The sight of a half-dozen frightened faces in the hall restored my self-possession. The servants had come up from below and stood crowding and jostling each other just as they had done three weeks before. At the sight of Hewson's cowering figure they began to moan and cry.

"Be quiet there!" exhorted Sweetwater, advancing upon them with the courage born of his triumphant success. "The old man whom you have doubtless thought the best-hearted and most reliable of you all has just confessed to the crime which has desolated this house and all but ruined the three young gentlemen, your masters. Cry away if you want to, but cry quietly and without giving the least alarm, for the good news has not gone upstairs yet, and this gentleman, who was the first to announce Mr. Gillespie's death to his sons, naturally would like the satisfaction of telling them that his murderer has been found. I have no doubt that Mr. George and his brother are to be found above."

"They be, sir, they be," spoke up a voice.
