THE DUST OF DEATH

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 as 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.

“Diphtheria!” he exclaimed. “Label’s type unless I am greatly mistaken. Some authorities are disposed to scoff at Dr. Label’s discovery. I was an assistant of his for four years and I know better. Fortunately I happen to know what the treatment—successful in two cases—was.”

He hurried from the house and returned a few minutes later breathlessly. He had some strange-looking, needle-like instruments in his hands. He took an electric lamp from its socket and substituted a plug on a flex instead. Then he cleared a table without ceremony and managed to hoist his patient upon it.

“Now please hold that lamp steadily thus,” he said. “Bravo, you are a born nurse! I am going to apply these electric needles to the throat.”

Hubert talked on more for the sake of his companion’s nerves than anything else. The still figure on the table quivered under his touch, his lungs expanded in a long, shuddering sigh. The heart was beating more or less regularly now. Fillingham opened his eyes and muttered something.

“Ice,” Hubert snapped, “have you got any ice in the house?”

It was a well-regulated establishment and there was plenty of ice in the refrigerat
