The door opened as he turned the handle, and he stepped softly into the hall. Everything seemed normal in the house. He could hear the ticking of a grandfather's clock further back on the stairs; but the noise which had first attracted his attention was not repeated. Gently closing the door to shut out the fog, he stood for a moment listening intently.

“Anybody here?” he demanded in a carrying voice.

There was no answer; but after a short time he heard again the sound which had puzzled him, evidently coming from the lighted room on the ground floor. Half a dozen swift steps took him to the door which he flung open.

“Good God! What's wrong with you?” he ejaculated, as his glance caught the only occupant of the smoke-room into which he had come.

On a chesterfield, a fair-haired young man was lying helpless. From the red stain on the lips, Dr. Ringwood guessed at a hæmorrhage of the lungs; and the quantity of blood on the boy's shirt-front and the dark pool on the carpet pointed to the severity of the attack. The youth's eyes caught the newcomer, and he beckoned feebly to the doctor. Ringwood crossed to the chesterfield and bent down. It hardly needed an expert to see that assistance had come too late. The sufferer made an effort, and the doctor stooped to catch the words.

“. . . Caught me . . . pistol . . . shot . . . thought it was . . . all right . . . never guessed . . .”

Dr. Ringwood bent closer.

“Who was it?” he demanded.

But that broken and gasped-out message had been the victim's last effort. With the final word, a cough shook him; blood poured from his mouth; and he fell back among the cushions in the terminal convulsion.

Dr. Ringwood saw the jaw drop and realised that he could be of no further service. Suddenly his weariness, accentuated by the strain of the drive through the fog, descended upon him once more. He straightened himself with something of an effort and gazed down at the body, feeling himself curiously detached from this suddenly-emergent mystery, as though it were no direct concern of his. Then, in his own despite, his cool medical brain began to work as though by some volition independent of his own. He drew out his notebook and jotted down the few disjointed words which he had caught, lest he should forget them later on.
