"I _must_ find the jewels," Iris mused, as she had done a hundred times before. "And I must do it by my wits. They are somewhere in safety--of that I'm sure, and, too, Aunt Ursula has left some hint, some clue to their hiding-place. If I'm to be of any help to Win, the first thing to do is to ferret out this matter. Then, we may be better able to trace the----"
Her thoughts were interrupted by the sight of what seemed to her to be a shadow, crossing the lawn below her. The shrubbery was dense, and the night dark, but she discerned a faint semblance of a person skulking among the trees. She sat motionless, but the shadow faded, and she could see nothing more of it. Concluding she had been mistaken, she sighed and was about to draw the blinds and make a light, when she was seized with a sudden spirit of nervous energy that impelled her to _do_ something--anything, rather than go to bed, where she knew she would only toss sleeplessly on the pillow.
Silently, not to disturb Miss Darrel, she crossed the hall and went downstairs. With only a vague notion of looking around, she went into her aunt's sitting room, and flashed on a light. It was the table lamp that had been found broken on the floor at the time of the tragedy, but that now, replaced by a new electrolier, gave a pleasant, soft light. Coiling up the long green cord, lest she trip on it, Iris sank into an easy chair near the table.
Restlessly, she arose and walked about the room. Though familiar with every detail, it looked strange to her, as a room does when one is the sole occupant. She opened the wall-safe, and stared into its emptiness. She pulled open some drawers of a cabinet, looked into a few boxes, and with no definite purpose, sat down at her aunt's desk. Disinterestedly, she looked over some books and papers, but she knew them all by heart. She ran over some bundles of letters, hoping to find a penciled memorandum on the backs, that had been hitherto unnoticed.
Nothing met her eye that seemed important, and she turned from the desk, her glance falling on the cretonne window curtains that overhung the lighter lace ones.
"Come out!" she cried, and then quickly, "no, _don't_ come out! Stay where you are! Who are you?"
