[THE DUST OF DEATH.]

The Story of the Great Plague of the Twentieth Century.

The front door bell tinkled impatiently; evidently somebody was in a hurry. Alan Hubert answered the call, a thing that even a distinguished physician might do, seeing that it was on the stroke of midnight. The tall, graceful figure of a woman in evening dress stumbled into the hall. The diamonds in her hair shimmered and trembled, her face was full of terror.

"You are Dr. Hubert," she gasped. "I am Mrs. Fillingham, the artist's wife, you know. Will you come with me at once.... My husband.... I had been dining out. In the studio.... Oh, please come!"

Hubert asked no unnecessary questions. He knew Fillingham, the great portrait painter, well enough by repute and by sight also, for Fillingham's house and studio were close by. There were many artists in the Devonshire Park district—that pretty suburb which was one of the triumphs of the builder's and landscape gardener's art. Ten years ago it had been no more than a swamp; to-day people spoke complacently of the fact that they lived in Devonshire Park.

Hubert walked up the drive and past the trim lawns with Mrs. Fillingham hanging on his arm, and in at the front door. Mrs. Fillingham pointed to a door on the right. She was too exhausted to speak. There were shaded lights gleaming everywhere, on old oak and armour and on a large portrait of a military-looking man propped up on an easel. On a lay figure was a magnificent foreign military uniform.

Hubert caught all this in a quick mental flash. But the vital interest to him was a human figure lying on his back before the fireplace. The clean-shaven, sensitive face of the artist had a ghastly, purple-black tinge, there was a large swelling in the throat.

"He—he is not dead?" Mrs. Fillingham asked in a frozen whisper.

Hubert was able to satisfy the distracted wife on that head. Fillingham was still breathing. Hubert stripped the shade from a reading lamp and held the electric bulb at the end of its long flex above the sufferer's mouth, contriving to throw the flood of light upon the back of the throat.
