Billy Kane was conscious only that he had reached out and grasped the footman’s arm. They were very black, the shadows of the house, and it was dark about him, but strange quick little red flashes seemed to dance and dart and shoot before his eyes; and in his brain the man’s words kept repeating themselves over and over in an insistent sort of way, and the words seemed meaningless except that they were pregnant with an overwhelming and numbing horror.

“For God’s sake, sir, let go my arm—you’re breaking it!” moaned the footman in a whisper.

The man’s voice seemed to clear Billy Kane’s brain. David Ellsworth—murdered! The horror was still there, but now there came a fury beyond control, and a bitter grief that racked him to the soul. David Ellsworth, his second father, the gentlest man and the kindest he had ever known—murdered! His hand dropped to his side, and, turning, he sprang up the few steps to the entrance just in front of him. He whipped out his key, opened the door, and stepped forward into the passageway. At his right was the door to the stenographer’s room, and beyond, opening from that room, was the door to the library. He felt for the door handle, for there was no light in the passage, and, finding it, opened the door—and stood there rigid and motionless like a man turned to stone. Across the blackness of the intervening room the library door was partially open, and sprawled upon the floor lay the figure of a white-haired man, only the hair was blotched with a great crimson stain—and it was David Ellsworth. And something came choking into Billy Kane’s throat, and a blinding mist before his eyes shut out the sight.

“In Heaven’s name, don’t go in there, sir!” Jackson was beside him again, whispering in his ear, and pulling the door softly shut. “Don’t, sir—don’t go—they’ll get you!”

“Get—me! What do you mean?” Billy Kane whirled on the man.

“For the love of God, sir,” pleaded Jackson, “don’t speak so loud! I’m risking my neck for you, as it is, sir. There’s a couple of plain-clothesmen waiting up in your room, sir, hiding there, and there’s another two hiding in the front hall.”

“Are you mad, Jackson!” Billy Kane’s voice was low enough now in its blank amazement.

“I’m telling you the truth, sir,” Jackson whispered tensely. “They’ve got you dead to rights, sir. There ain’t a chance, except to run for it—and that’s what I’d do, sir, if I were you, Mr. Kane. I didn’t mean you to enter the house at all, but you acted so quick I couldn’t stop you.”

Billy Kane’s two hands fell in an iron grip on the other’s shoulders, and in the darkness he bent his head forward to stare into the man’s face and eyes.

“You mean, Jackson,” he said hoarsely, “that you believe I did that?”
