the shadow which he believed to be hers on the window-blind of the room where he had by discreet inquiry located her.  Whether his memory was stimulated by his quest he never knew, but presently he was able to recall step by step and incident by incident his early courtship of her and the brief days of their married life.  He even remembered the day she accepted him, and even dwelt upon it with a sentimental thrill that he probably never felt at the time, and it was a distinct feature of his extraordinary state of mind and its concentration upon this particular subject that he presently began to look upon himself as the abandoned and deserted conjugal partner, and to nurse a feeling of deep injury at her hands!  The fact that he was thinking of her, and she, probably, contented with her lot, was undisturbed by any memory of him, seemed to him a logical deduction of his superior affection.

It was, therefore, quite as much in the attitude of a reproachful and avenging husband as of a merely curious one that, one afternoon, seeing her issue from her house at an early hour, he slipped down the stairs and began to follow her at a secure distance.  She turned into the principal thoroughfare, and presently made one of the crowd who were entering a popular place of amusement where there was an afternoon performance.  So complete was his selfish hallucination, that he smiled bitterly at this proof of heartless indifference, and even so far overcame his previous caution as to actually brush by her somewhat rudely as he entered the building at the same moment.  He was conscious that she lifted her eyes a little impatiently to the face of the awkward stranger; he was equally, but more bitterly, conscious that she had not recognized him!  He dropped into a seat behind her; she did not look at him again with even a sense of disturbance; the momentary contact had evidently left no impression upon her.  She glanced casually at her neighbors on either side, and presently became absorbed in the performance.  When it was over she rose, and on her way out recognized and exchanged a few words with one or two acquaintances.  Again he heard her familiar voice, almost at his elbow, raised with no more consciousness of her contiguity to him than if he were a mere ghost.  The thought struck him for the first time with a hideous and appalling significance.  What was he but a ghost to her—­to every one!  A man dead, buried, and forgotten!  His vanity and self-complacency vanished before this crushing realization of the hopelessness of his existence.  Dazed and bewildered, he mingled blindly and blunderingly with the departing crowd, tossed here and there as if he were an invisible presence, stumbling over the impeding skirts of women with a vague apology they heeded not, and which seemed in his frightened ears as hollow as a voice from the grave.
