"There is something very astonishing about this whole affair," he exclaimed. "What do you make of those?" He indicated a series of dark smudges upon the bedspread, arranged in little groups.
Baker bent over and examined the marks with an exclamation of surprise.
"Why—they look like finger prints," he cried. "Large finger prints."
"It is impossible to say whether they are finger prints or not," Duvall replied. "As you see, there are a great many of them, very confusingly arranged. But there is something else, that you have not noticed. What do you suppose could have made a mark like this?" He pointed to a long straight dark line, which extended half way across the counterpane, and pointed directly toward the window which faced upon the court. The line was very faint, but clearly defined, as though someone had laid a thin dusty stick across the bed.
"I can't make anything of it," Baker exclaimed, gazing toward the window.
"Nor can I," said Duvall. "At one time, because of certain indentations on the letters found in this room, I had thought that they might have been introduced through the partly opened window by means of a long rod, a fishing pole, perhaps. This mark on the counterpane appears to bear out that theory. The smudges which look like finger prints may have been merely the points at which the end of the pole, or whatever was attached to the end of the pole, came in contact with the bed. All that is perfectly supposable. But you can see for yourself that if a long pole were thrust through the window, raised as the latter was but a trifle above the level of the bed, the other end of such a pole must of necessity have been held at approximately the same level, and the only point outside the window from which it could have been so held is in the air, forty feet above the bottom of the court! The thing is absurd."
"There is, of course, the window of the apartment below," Baker suggested. "Might not it have been used?"
"I thought of that," Duvall replied. "You can see for yourself that even a tall man standing on the window sill below, would find not only his hands, but even his head, far below the sill of this window, nor could anyone so support themselves, without something to hold on to. But all that is beside the question. The people in the apartment below are friends of Mrs. Morton's, a middle-aged man and his wife, with two young children. They are eminently respectable people, and quite above suspicion."
"Then I give the thing up," exclaimed Baker. "Suppose we have a talk with Miss Morton."
They found the girl lying on a couch in the library, with her mother sitting beside her. She seemed very weak and quiet, but in full possession of her faculties. Duvall drew up a chair, and asked her if she felt able to tell them what had occurred.
