“Beg pardon, sir,” Wilkins interrupted. “Mary has just brought the tray downstairs again. She says she knocked and knocked, and couldn’t get an answer.”

The Attorney General and his daughter exchanged glances. It was impossible to tell which was the paler. Without a word he turned and hastened out of the room. He hardly noticed the excited servants who, attracted by the cry, had already gathered in the spacious hall outside the door of his private office. With swift, decisive step he crossed the room and stood in front of the two opened doors. A cry of unutterable horror escaped him. For one dreadful moment the room swam around him, and there was a roaring in his ears of a thousand Niagaras.

“Father?”

With a violent effort he pulled himself together. “Do not enter,” he said, sternly, to the shrinking girl who had remained by the hall door. “This is no sight for you. Wilkins, send at once for Doctor Davis. Clark, close that door, and see that no one comes in except the doctor. Then telephone the Department that I shall not be there to-day.” His orders were obeyed instantly.

The Attorney General turned back to the safe; to that still figure which was keeping vigil over his belongings. The pitiless light of a sunny morning shone full on the beautiful face. The wonderful Titian hair, her greatest glory, was coiled around the shapely head, and her low-cut evening dress was scarcely disarranged as she crouched on one knee leaning her weight on her left arm, which was pressed against the door-jamb of the safe. Her lips were slightly parted, and her blue eyes were wide open, the pupils much dilated. No need to feel pulse or heart; to the most casual observer it was apparent that she was dead.

His beautiful young wife! Edmund Trevor groaned aloud and buried his face in his hands. Clark watched him for a moment in unhappy silence; then moved quietly over to the window and looked out with unseeing eyes into the garden.

The large mottled brick- and stone-trimmed house was situated on one of Washington’s most fashionable corners, Massachusetts Avenue and Dupont Circle. On being appointed Attorney General, Trevor had taken it on a long lease. He had selected it from the many offered because it was very deep on the 20th Street side, thus allowing the drawing-room, library, and dining-room to open out of each other.

On the right of the large entrance hall was a small reception room, and back of it the big octagonal-shaped room, with its long French windows opening into the enclosed garden, that had appealed to him for his own private use, as a den, or office. And he was particularly pleased with the huge safe, more like a vault, which had been built in one of the large old-fashioned closets by the owner. It had been useful to the Attorney General on many occasions.

The silence was broken by a tap at the door.

“Doctor Davis, sir,” announced Wilkins.
