of the deceased Mr. Holmes.

There was a fire in the room, and before proceeding further, I cauterized that prick with the end of a red-hot poker. Then I made my adieux to Mrs. Holmes and went immediately to a chemist friend of mine.

"Test the end of this bit of steel for me," said I. "I have reason to believe it carries with it a deadly poison."

He took the toy, promised to subject it to every test possible and let me know the result. Then I went home. I felt ill, or imagined that I did, which under the circumstances was almost as bad.

Next day, however, I was quite well, with the exception of a certain inconvenience in my thumb. But not till the following week did I receive the chemist's report. It overthrew my whole theory. He had found nothing, and returned me the bit of steel.

But I was not convinced.

"I will hunt up this John Graham," thought I, "and study him."

But this was not so easy a task as it may appear. As Mrs. Holmes possessed no clue to the whereabouts of her quondam lover, I had nothing to aid me in my search for him, save her rather vague description of his personal appearance and the fact that he was constantly interrupted in speaking by a low, choking cough. However, my natural perseverance carried me through. After seeing and interviewing a dozen John Grahams without result, I at last lit upon a man of that name who presented a figure of such vivid unrest and showed such desperate hatred of his fellows, that I began to entertain hopes of his being the person I was in search of. But determined to be sure of this before proceeding further, I confided my suspicions to Mrs. Holmes, and induced her to accompany me down to a certain spot on the "Elevated" from which I had more than once seen this man go by to his usual lounging place in Printing-house Square.

She showed great courage in doing this, for she had such a dread of him that she was in a state of nervous excitement from the moment she left her house, feeling sure that she would attract his attention and thus risk a disagreeable encounter. But she might have spared herself these fears. He did not even glance up in passing us, and it was mainly by his walk she recognized him. But she did recognize him; and this nerved me at once to set about the formidable task of fixing upon him a crime which was not even admitted as a fact by the authorities.

He was a man-about-town, living, to all appearance, by his wits. He was to be seen mostly in the downtown portions of the city, standing for hours in front of some newspaper office, gnawing at his finger-ends, and staring at the passers-by with a hungry look that alarmed the timid and provoked alms from the benevolent. Needless to say that he rejected the latter expression of sympathy, with angry contempt.

His face was long and pallid, his cheek-bones high and his mouth bitter and resolute in expression. He wore neither beard nor mustache, but made up for their lack by an abundance of light brown hair, which hung very nearly to his shoulders. He stooped in standing, but as soon as he moved, showed decision and a certain sort of pride which caused him to hold his head high and his body more than usually erect. With all these good points his appearance was decidedly sinister, and I did not wonder that Mrs. Holmes feared him.

My next move was to accost him. Pausing before the doorway in which he stood, I addressed him some trivial question. He answered me with sufficient politeness, but with a grudging attention which betrayed the hold which his own thoughts had upon him. He coughed while speaking and his eye, which for a moment rested on mine, produced upon me an impression for which I was hardly prepared, great as was my prejudice against him. There was such an icy composure in it; the composure of an envenomed nature conscious of its superiority to all surprise. As I lingered to study him more closely, the many dangerous qualities of the man became more and more apparent to me; and convinced that to proceed further without deep and careful thought, would be to court failure where triumph would set me up for life, I gave up all present attempt at enlisting him in conversation, and went my way in an inquiring and serious mood.

In fact, my position was a peculiar one, and the problem I had set for myself one of unusual difficulty. Only by means of some extraordinary device such as is seldom resorted to by the police of this or any other nation, could I hope to arrive at the secret of this man's conduct, and triumph in a matter which to all appearance was beyond human penetration.

But what device? I knew of none, nor through two days and nights of strenuous thought did I receive the least light on the subject. Indeed, my mind seemed to grow more and more confused the more I urged it into action. I failed to get inspiration indoors or out; and feeling my health suffer from the constant irritation of my recurring disappointment, I resolved to take a day off and carry myself and my perplexities into the country.

I did so. Governed by an impulse which I did not then understand, I went to a small town in New Jersey and entered the first house on which I saw the sign "Room to Let." The result was most fortunate. No sooner had I crossed the threshold of the neat and homely apartment thrown open to my use, than it recalled a room in which I had slept two years before and in which I had read a little book I was only too glad to remember at this moment. Indeed, it seemed as if a veritable inspiration had come to me through this recollection, for though the tale to which I allude was a simple child's story written for moral purposes, it contained an idea which promised to be invaluable to me at this juncture. Indeed, by means of it, I believed myself to have solved the problem that was puzzling me, and relieved beyond ex-pression, I paid for the night's lodging I had now determined to forego, and returned immediately to New York, having spent just fifteen minutes in the town where I had received this happy inspiration.

My first step on entering the city was to order a dozen steel coils made similar to the one which I still believed answerable for James Holmes' death. My next to learn as far as possible all of John Graham's haunts and habits. At a week's end I had the springs and knew almost as well as he did himself where he was likely to be found at all times of the day and night. I immediately acted upon this knowledge. Assuming a slight disguise, I repeated my former stroll through Printing-house Square, looking into each doorway as I passed. John Graham was in one of them, staring in his old way at the passing crowd, but evidently seeing nothing but the images formed by his own disordered brain. A manuscript-roll stuck out of his breast-pocket, and from the way his nervous fingers fumbled with it, I began to understand the restless glitter of his eyes, which were as full of wretchedness as any eyes I have ever seen.

Entering the doorway where he stood, I dropped at his feet one of the small steel coils with which I was provided. He did not see it. Stopping near him I directed his attention to it by saying:

"Pardon me, but did I not see something drop out of your hand?"

He started, glanced at the seeming inoffensive toy at which I pointed, and altered so suddenly and so vividly that it became instantly apparent that the surprise I had planned for him was fully as keen and searching a one as I had anticipated. Recoiling sharply, he gave me a quick look, then glanced down again at his feet as if half expecting to find the object vanished which had startled him. But, perceiving it still lying there, he crushed it viciously with his heel, and uttering some incoherent words, dashed impetuously from the building.

Confident that he would regret this hasty impulse and return, I withdrew a few steps and waited. And sure enough, in less than five minutes he came slinking back. Picking up the coil with more than one sly look about, he examined it closely. Suddenly he gave a sharp cry and went staggering out. Had he
