troubled burglar.

"And to demonstrate to his somewhat cynical cast of mind that there's nothing extraordinary in his particular line of activity, I propose to return it in the same manner that it was taken."

Benson looked troubled.

"I beg pardon, sir, but mightn't it get us all into a bit of trouble? Couldn't we leave it until morning, sir, and talk it over quiet-like with your friend Mr. McCooey, or with Lieutenant Belton, sir, or the gentleman from the Pinkerton office?"

"And have a cuff-shooter running for help over such a triviality? Never, Benson, never! You will make yourself comfortable here with this gallant gentleman of the black-jack, and keep this handsome Colt of his quite close about you while you're doing it. For I'm going to take this piece of porcelain back where it belongs, even though I have to face a dozen lap-dogs and frighten every housemaid of Twelfth Street into hysterics."

Nobody, I have more than once contended, is altogether sane after midnight. This belief came back to me as I stood before that gloomy-fronted Fifth Avenue house, in that ebb-tide hour of the night when even Broadway is empty, wondering what lay behind the brownstone mask, asking myself what dangers lurked about that inner gloom, speculating as to what sleepers stirred and what eyes, even as I stood there, might be alert and watching.

As Benson had suggested, I might have waited decorously until daylight, or I might have quietly ascended the wide stone steps and continued to ring the electric push-bell until a sleepy servant answered it. But that, after all, seemed absurdly tame and commonplace. It was without the slightest tang of drama, and I was as waywardly impatient to try that enticing tip-tilted instrument of steel on an opposing door as a boy with a new knife is to whittle on the nursery woodwork.

There was a tingle of novelty even in standing before a grimly substantial and altogether forbidding-looking house, and being conscious of the fact that you had decided on its secret invasion. I could no longer deny that it took a certain crude form of nerve. I was convinced of this, indeed, as I saw the approaching figure of a patrolman on his rounds. It caused me, as I felt the jimmy like a staybone against my ribs, and the flashlight like a torpedo-head in my pocket, to swing promptly about into Twelfth Street and walk toward Sixth Avenue. I experienced a distinct glow of satisfaction as the patrolling footsteps passed northward up the quietness of the avenue.

But the house itself seemed as impregnable as a fortress. It disheartened me a little to find that not even a basement grill had been disturbed. For the second time I turned and sauntered slowly toward Sixth Avenue. As I swung eastward again I found that the last house on the side-street, the house abutting the Fifth Avenue mansion which was the object of my attack, was vacant. Of that there could be no doubt. Its doors and windows were sealed with neatly painted shutters.

This, it occurred to me, might mark a possible line of approach. But here again I faced what seemed an impregnable position. I was backing away a little, studying that boarded and coffin-like front, when my heel grated against the iron covering of a coal-chute. This coal-chute stood midway between the curb and the area railing. I looked down at it for a moment or two. Then something prompted me to test its edge with the toe of my shoe. Then, making quite sure that the street was empty, I stooped down and clutched at the edge of the iron disk. It was quite heavy. But one tug at it showed me that its lock-chain had been forced apart.

It took but a moment to lift the metal shield to one side of the chute-head. It took but another moment to lower myself into the chute itself. I could see that it was a somewhat ignominious beginning. But I felt buoyantly sure that I was on the right track. It took an effort to work the iron disk back over the opening. It also required many strange contortions of the body to worm my way down into that narrow and dirty tunnel.

My rather peremptory advent into the coal-bin resulted in a startling amount of noise, noise enough to wake the soundest of sleepers. So I crouched there for several seconds, inhaling dust, and listening and wondering whether or not the walls above me harbored a caretaker. Then I took out the pocket searchlight, and, with the pressure of a finger, directed my ray of illumination against a wooden partition bisected by a painted wooden door.

A distinct sense of disappointment swept through me as I stooped down to examine this door and found that it had already been forced open. I knew, however, that I was following in the footsteps of my more experienced predecessor. Then came a storeroom, and then a laundry-room, with another jimmied door at the head of the stairway leading to the first floor.

Here I stood waiting and listening for some time. But still again nothing but darkness and silence and that musty aroma peculiar to unoccupied houses surrounded me. I felt more at home by this time, and was more leisurely in my survey of the passage upward. I was, of course, confronted by nothing more disturbing than ghost-like furniture covered with ticking and crystal-hung chandeliers encased in cheesecloth. I began to admire my friend the burglar's astuteness in choosing so circuitous and yet so protected a path. There was almost genius in it. His advance, I felt sure, was toward the roof. As I had expected, I found the scuttle open. The lock, I could see, had been quite cleverly picked. And, so far, there had not been a mishap.

Once out on the housetop, however, I foresaw that I would have to be more careful. As I clambered up to the higher coping-tiles that marked the line of the next roof, I knew that I had actually broken into the enemy's lines. Yet the way still seemed clear enough. For, as I came to the roof-scuttle of the second house I found that it, too, remained unlocked. My predecessor had made things almost disappointingly easy for me. Yet, in another way, he had left things doubly dangerous. I had to bear the brunt of any mis-step he may have made. I was being called to face the responsibility of both his intrusion and my own.

So it was with infinite precaution that I lifted the scuttle and leaned over that little well of darkness, inhaling the warmer air that seeped up in my face. With it came an odor quite different to that of the house I had just left. There was something expository in it, something more vital and electric, eloquent of a place inhabited, of human beings and their lairs and trails, of movement and life and vaguely defined menaces. It was, I fancied, a good deal like that man-smell which comes down-wind to a stalked and wary elk.

I stepped down on the iron ladder that led into the uncertain darkness, covering the trap after me. I began to feel, as I groped my way downward, that the whole thing was becoming more than a game. I was disturbed by the thought of how deep I had ventured into an uncertainty. I began to be oppressed by the thought of how complicated my path was proving. I felt intimidated by the undetermined intricacies that still awaited me. A new anxiety was taking possession of me, a sort of low fever of fear, an increasing impatience to replace my precious porcelain, end my mission, and make my escape to the open.

It began to dawn on me, as I groped lower and lower down through the darkness, that a burglar's calling was not all beer and skittles. I began to feel a little ashamed of my heroics of an hour before.

Then I drew up, suddenly, for a sound had crept to my ears. The tingle that ran through my body was not wholly one of fright. Yet, as I stood there in the darkness with one hand against the wall, I caught the rhythm of a slow and muffled snoring. There was something oddly reassuring in that reiterated vibration, even though it served to emphasize the dangers that surrounded me. It was not unlike the sound of a bell-buoy floating up to a fog-wrapped liner's bridge.

I was no longer a prey to any
