There was a message in typewritten characters upon the sheet, and Mrs. Morton read it with a groan of despair.

"Only twenty-nine days more!" the message said. "We shall not fail." Below the words grinned the frightful death's head seal.

CHAPTER II

Mrs. Harriet Morton was a courageous woman, but when she read the second threat against her daughter, she was filled with instant indignation and horror. The thing was so appallingly mysterious, so utterly without reasonable explanation.

Ruth had left the room but a few moments before. Certainly the letter was not upon the floor then. The maid, Nora, had gone with her. That removed her from any suspicion, even had such a thought been reasonable or possible, and Mrs. Morton felt it was not. The only other person in the apartment was Mary, their old cook, a negro from the south, who had been a faithful and patient member of the Morton household for over ten years. That she could have had a hand in placing this mysterious message in Ruth's bedroom seemed incredible, not to be entertained for a moment. And yet, there was the message, appallingly simple, direct, threatening. "Only twenty-nine days more!" Mrs. Morton shuddered.

She glanced about the room. How had the letter come there? Certainly not by means of the door. Yet it seemed equally out of the question that it could have been brought in through one of the windows.

There were two in the room, one facing to the front, and opening upon a court, the other in the rear, overlooking the yards of the houses on the next street. She went to the front window, which was raised only a few inches, and gazed out.

Below her stretched the wide court, flanked on one hand by the side of the apartment building, on the other by the blank wall of an adjoining house. The latter was some ten feet from where she stood, and there were no windows in it! She turned to the window at the other side of the room.

Here a fire escape led down to an alley at the rear of the building. Could it have been in this way that the letter had been delivered? The thing seemed impossible. Not only was the window closed, but she knew that the ladders did not reach all the way to the ground, the last section being pulled up, to be dropped only in case of fire. With a mystified look she returned to the center of the room.

The letter grinned at her from the dresser, on which she had left it. Ruth must never hear of the matter, she knew. Taking it up, she placed it in the bosom of her dress along with the one which had arrived earlier in the day. Then she sat down to decide what she had best do next.
