Turning back through the hall, she dispensed with the hand-lamp, entering the darkened study. Here all windows had been closed and the outer shades drawn—O'Hagan's last act before leaving with the suit-case: additional proof that Maitland was not expected back that night. For the temperature was high, the air in the closed room stifling.

Crossing to the windows, the girl drew down the dark green inner shades and closed the folding wooden shutters over them. And was conscious of a deepened sense of security.

Next going to the telephone, she removed the receiver from the hook and let it hang at the full length of the cord. In the dead silence the small voice of Central was clearly articulate: "What number? Hello, what number?"—followed by the grumbling of the armature as the operator tried fruitlessly to ring the disconnected bell. The girl smiled faintly, aware that there would now be no interruption from an inopportune call.

There remained as a final precaution only a grand tour of the flat; which she made expeditiously, passing swiftly and noiselessly (one contemplating midnight raids does not attire one's self in silks and starched things) from room to room, all comfortably empty. Satisfied at last, she found herself again in the study, and now boldly, mind at rest, lighted the brass student lamp with the green shade, which she discovered on the desk.

Standing, hands resting lightly on hips, breath coming quickly, cheeks flushed and eyes alight with some intimate and inscrutable emotion, she surveyed the room. Out of the dusk that lay beyond the plash of illumination beneath the lamp, the furniture began to take on familiar shapes: the divans, the heavy leather-cushioned easy chairs, the tall clock with its pallid staring face, the small tables and tabourettes, handily disposed for the reception of books and magazines and pipes and glasses, the towering, old-fashioned mahogany book-case, the useless, ornamental, beautiful Chippendale escritoire, in one corner: all somberly shadowed and all combining to diffuse an impression of quiet, easy-going comfort.

Just such a study as he would naturally have. She nodded silent approbation of it as a whole. And, nodding, sat down at the desk, planting elbows on its polished surface, interlacing her fingers and cradling her chin upon their backs: turned suddenly pensive.

The mood held her but briefly. She had no time to waste, and much to accomplish…. Sitting back, her fingers sought and pressed the clasp of her hand-bag, and produced two articles—a golden cigarette case and a slightly soiled canvas bag. The Maitland jewels were returning by a devious way, to their owner.

But where to put them, that he might find them without delay? It must be no conspicuous place, where O'Hagan would be apt to happen upon them; doubtless the janitor was trustworthy, but still…. Misplaced opportunities breed criminals.

It was all a risk, to leave the treasure there, without the protection of nickeled-steel walls and timelocks; but a risk that must be taken. She dared not retain it longer in her possession; and she would contrive a way in the morning to communicate with Maitland and warn him.

Her gaze searched the area where the lamplight fell soft yet strong upon the dark shining wood and heavy brass desk fittings; and paused, arrested by the unusual combination of inverted bowl and super-imposed book. A riddle to be read with facility; in a twinkling she had uncovered the incriminating hand-print—incriminating if it could be traced, that is to say.
