Driven by some vague detective instinct, the bewildered parent now glanced curiously at the vacant shelves to see what his son had taken up to the attic. The youth's library was plainly and rigidly classified, so that one might tell at a glance the books or at least the kind of books which had been withdrawn. On this occasion Mr. Ward was astonished to find that nothing of the occult or the antiquarian, beyond what had been previously removed, was missing. These new withdrawls were all modern items; histories, scientific treatises, geographies, manuals of literature, philosophic works, and certain contemporary newspapers and magazines. It was a very curious shift from Charles Ward's recent run of reading, and the father paused in a growing vortex of perplexity and an engulfing sense of strangeness. The strangeness was a very poignant sensation, and almost clawed at his chest as he strove to see just what was wrong around him. Something was indeed wrong, and tangibly as well as spiritually so. Ever since he had been in this room he had known that something was amiss, and at last it dawned upon him what it was.
