"What's the mystery?" Grace went on, with an amused smile. "You haven't told me, you know. Has she lost her jewels, or only her husband?"

Duvall raised his hand.

"No questions, my dear. This is a professional matter. But I don't mind telling you this much, if I ever become a motion picture 'fan,' you'll have her to thank for it."

"Really. Then I'm glad she came. I hate going alone. And it seems I shall also have to thank her for a trip to New York. She has my eternal gratitude. Now I'm going up to pack."

Duvall resumed his seat, and once more took up his examination of the letters Mrs. Morton had left with him, but they told him little. There were the usual individual peculiarities in the typewritten characters, but that was about all he could discover. The letter paper, while of excellent quality, was such as might be bought at any first-class stationery store. The death's head seal, of course, was highly individual, but to trace anyone by means of it presented almost insuperable difficulties. To find the seal, one must of necessity first find its owner, and then the chase would be over. He replaced the letters in his pocket book, and went to his room to make ready for their journey.

CHAPTER IV

Mrs. Morton returned to New York that afternoon, greatly pleased with the results of her trip. That she had been able to enlist the services of Richard Duvall gave her a sense of security. She found Ruth at home, safe and well, with no further threats or warnings to disturb her peace of mind. The girl was absorbed in her new rôle. The picture promised to be the most successful of her career.

The following morning Mrs. Morton rose early, in order to go through the mail before Ruth had an opportunity to do so. The shock caused by the first threatening letter had passed from the girl's mind. The second she knew nothing of. Mrs. Morton was determined that if any more arrived, she should not see those either.

Trembling with eagerness she opened the pile of letters, but found nothing. With a sigh of relief she turned away. Perhaps, after all she had exaggerated the importance of the matter. Half an hour later, while Ruth was eating her breakfast, a messenger boy arrived with a telegram, addressed to Miss Ruth Morton. The maid, seeing no reason to do otherwise, brought it to the girl as she sat at the table. Mrs. Morton, who had been at the rear of the apartment, hurried in as she heard the sound of the doorbell, but by the time she had reached the dining room, Ruth had already opened and read the message. She sat staring at a bit of yellow paper, her face pale and drawn.

"What is it, dear?" Mrs. Morton cried, hurrying to her side.
