"I will be here," I doggedly replied. I was resolved to let nothing, not even my prejudices as a gentleman, interfere with the successful pursuit of this undertaking. "Will his story contain any reference to Miss Meredith?"

"Not the least in the world. Why?"

"Because I always find it difficult to sit still when I hear ladies spoken of in any way short of the deepest respect; and you say he is not a gentleman."

"He won't transgress to that degree. If he does, trust to my bringing him to order. Sorry I must place an embargo on the cigars you will find on the table. Smoking on your part would give away your presence; for the man whose story you are coming to hear is one of those fellows who smell a rat round the corner. In other words, he's a private detective with whom I was once thrown in a peculiar way. What now?"

"Perhaps he's the very fellow I want. I have use for a private detective."

"So--I--suppose."

This sentence, so long in coming, was uttered in a peculiar way, and at the moment we were rising from table. Though I said nothing, I experienced an access of courage. Unpromising as Sam's manner had been, he was really in sympathy with me, and willing to lend me a helping hand.

That day the law suffered, or, rather, I should say, such clients as were misguided enough to come to my office. The uncertain nature of the disclosure I awaited, and the doubt as to which of the three brothers it would chiefly affect, kept me restless up to the hour set apart for my return to Sam Underhill's room. Not till nine o'clock arrived and I found myself in the small apartment called his den, did I recover my poise and show anything like a steady countenance in the long mirror stretched above the mantel. This has always been a characteristic of mine. Great agitation up to the moment of action, and then an unnatural calmness. In this case it was an event I awaited; but the characteristic remained unchanged.

Sam Underhill, on the contrary, never appeared more at his ease. I could hear him singing between the whiffs of his cigar, and, as I followed the mellow strains of one of the finest tenors I have ever known, I recalled the fact that I myself had not sung a note since the experience which had made such heavy inroads into my life. Was I growing misanthropic? Sam had not been without his dark days. I remembered quite well all the talk that went about at the time of his mad pa.s.sion for Dorothy Loring,--that bewitching madcap who afterwards found her match in Steve Wilson,--and I could not reconcile that disappointment with his present gaiety.

But these reflections cannot be of any interest to my readers; enough that they occupied me at the time and killed my impatience, till a sudden stoppage in the strain I objected to warned me that the expected visitor had arrived. I squared myself for the ordeal, held my breath, and prepared to listen.

The greetings were commonplace. Sam is a proud chap and does not put himself out much for anybody. To this man he scarcely showed common courtesy. Perhaps he was afraid of awakening distrust by any betrayal of interest in the coming interview; perhaps he recognised that a barely civil greeting was all the man expected or desired.

"Halloo, Yox!"

"Good evening, Mr. Underhill."

"Did I ask you to call on me to-night?"

"You certainly did, Mr. Underhill, and set the hour."

"Well, well, I suppose you are correct. Sit down. My memory is not much longer than this cigar, which you may observe is almost smoked up. Have one, Yox; you won't get a better in your shop; and now, what have you come to tell me?"

"Not much. Dennison bought seven shares last Tuesday and Little invested in as many more yesterday. Both men show confidence, and to-morrow's report will be all you can wish."

"Good! How much do I owe you? Will that do?"

I heard a rustle, then a short laugh preceding the remark, "You might halve it and still please me. Oh, I'll take it. Not too much grist comes to my mill."

Here there was a silence. Underhill was evidently lighting a fresh cigar. When they spoke again it was to drift into generalities, to which I listened with an impatience in marked contrast to the complacency of Sam, who seemed just too tired to live; that is, if I could judge from his tone and the total absence of interest he expressed in anything said either by himself or his somewhat vulgar guest. But suddenly there was a change, not in Underhill, whose voice was even more languishing than before, but in myself; for I heard Sam remark between two prolonged whiffs:

"What is that story you were trying to tell me the other night about the row in lower ---- Street? I thought it promised to be interesting at the time, but the other fellows were in such a hurry I couldn't stay to hear it out. Tell it again, Yox, just as you did then; perhaps it will wake me up."

The answer came more quickly than I expected.

"Oh, that? Well, I don't mind. It was a curious adventure and brought me too near the police for me to forget it in a hurry. I wish I knew who that fellow was. Did I show you the match-box I found in one of the pockets of the coat he gave me? The monogram----"

"Never mind the monogram. We'll talk about that afterwards," broke in Sam in the sleepiest tones imaginable. "I don't care so much about the man as the way he acted. This struck me as being strange for a gentleman. But begin, Yox; you relate adventures well. I have heard you talk more than once."

Yox, who was not above flattery, hemmed, hawed, and launched out in the following tale. I transcribe his words as nearly as I can remember them. At first he did not interest me much.

"You see, I had business at old Mother Merry's. Do you know the place?

It's not likely, so I will describe it; you need to know something about it in order to understand my story.

"It's an old fish-market, or, rather, that was its use once; now it's a sort of lodging-house, standing half on the dock and half on piles, somewhere down near ---- Street. I like the place. That is, it has a mysterious air which we fellows don't object to. Seen from the docks and in daylight, it has the appearance of four squat walls without windows. But if you take the trouble to crawl around on the river side, you will find two glazed loopholes overlooking the water, one on the lower story and one under the roof. There is also, I am told, a sky-light or two up above, but I can't swear to that. By night, the one bright glimmer you see on getting near it shines through the door.

This stands open in the summer, or, rather, the upper half of it does, for it is made in two parts, like the old Dutch ones you see in the pictures; but in winter time an agreeable light shines through the four small holes arranged along the top half. A calico curtain blows in and out of this door on such nights as we have been having lately; for Mother Merry likes a fire, and the little stove she sits at, netting, heats the one big room below to smotheration, and the men won't stand it. If this curtain blows high you can, if you're nervy enough, get a peep at the inside, stewing with a horrible smell of fish, and bright with kerosene lamps and the busy little stove. You won't see much furniture, for Mother Merry don't spend her money on anything she can do without; but there is a table or two and some chairs, and in one of the corners a door which sometimes stands half open, but more often is to be seen tight shut. Behind this door whatever mischief the house hides takes place. You can tell this from the old woman's eye, which is always on it; and, if you know her well, it is quite enough to watch her twitching underlip to satisfy yourself as to whether the mischief is big or little; prosperous in its character, or of a kind likely to damage her reputation and empty her well-stuffed pockets. She is no fool, this old Mother Merry; and though she has not much of what we men call nerve, and trembles like a leaf at the approach of a policeman, she has more control than you would think over the tough crowd of boatmen who knock their heads together in that little room. I have even been told that she is feared quite beyond all reason by the few stray females who find a refuge in the scanty garret rooms, which have given to this shanty the highfalutin name of lodging-house. What harm goes on under her twinkling red eye, I do not know. I have been in the place altogether three times, but have never yet found out what that door conceals. The men play at some sort of game around a large table, on which black bottles and thick gla.s.ses take up as much room as the cards; but I do not think it is gambling only which makes it next to impossible for a fellow to get in there at night. There is something else--but I won't stop over that. It is a h.e.l.l of a place, as you can judge, and unless one's business led him there, scarcely a spot where a man would brag of being found.

"One night--the night I am telling you about--I got in, but got in late. There was some sort of pa.s.sword necessary, and I had a hard time getting hold of it, and a harder time yet making old Mother Merry hear it when I had got hold of it. Yet she isn't deaf and doesn't pretend to be. This trouble over, and the door pa.s.sed, I encountered another check. A man was there; a slouchy, disreputable wretch, and it was he, instead of Mother Merry, who was watching that mysterious door, which for once stood far enough ajar for one room to share the smells, sights, and uproar of the other. I did not like this man. I did not like the way he stood, or looked, or held his tongue. There was something peculiar and unnatural in his whole manner, and I glanced at Mother Merry to see what she thought of him.

"Evidently nothing bad; for she moved about quite comfortable-like, and did not so much as look at the door I had never before seen her let out of her sight a moment.

"'Who can he be?' I naturally asked myself, a little put out by my doubts; for my business would soon take me into the inner room, and I did not like to imagine myself under his eye.

"'Drink!' I suddenly shouted, to see if I could make any impression on him.

"But I might as well have shouted at a hitching-post. Mother Merry brought me whiskey, but the man did not budge. I began to think of putting off my affair to a more convenient season, when I was taken with a sudden curiosity to see just what he was staring at.

"Approaching gently, I looked over his shoulder. A portion of the inside room was all I could see, but in that portion sat a man with a red face and a cruel jaw. It was this face which held the attention of the boatman before me; and while I was wondering what he found in it to hold him stock-still for so long, I heard a sigh escape from under the coa.r.s.e jacket I dreaded touching with my own, and, much amazed at this show of feeling in a den of such boiled-down filth and wickedness, I moved back to where Mother Merry stood, and whispered in her ear:

"'Who's that man? Do you know him? Has he any business here?'

"Her gaunt shoulders lifted in a shrug--she is far from jolly, cheerful as her name is--then she drew near the man and I saw her touch him. At that, or some low words she uttered, he roused and cast a quick look about him, then he pointed towards a door on the other side of the room.

"She answered by a nod, and he moved off with a poor try at a slouchy gait. When I saw this I knew he was no sailor.

"As the door closed behind him, a sound of women screaming and scolding came from the docks, then a child's cry cut into the night, after which there was quiet in that quarter and in the house, too. For Mother Merry, with a scared look, jumped towards the room where the men were sitting, and, pushing her way in, held up her hand so as to draw all eyes.

"'The warning,' she cried. 'It's the cops! See if you can get out by the window.'

"One of the men arose and went to the window, looked out, and came crawling back, putting out a light as he did so.

"'They're on the water,' he whispered; and, whether I am a fool or not, that whisper sent the creeps up my back.

"'Both front and back?' she cried. 'That means business; you'll have to squeeze into the hole, boys.'

"Another light went out.

"Meanwhile I had crept to the door.

"''Ware there! that fellow's trying to sneak,' shouted a voice.

"I drew back. Old Merry came to my aid.

"'Don't be a fool,' she whispered. 'Stay here or they'll think you're in with them!'

"The growl of some half-dozen of them brought the warning home. I laughed and got in line with the boys, grumbling aloud as I did so:

"'Then they'll make a mistake. If you are wanted by the cops, I am, too. But how about that other fellow?' I whispered, getting close to Mother Merry in the hubbub.

"She didn't hear me; she was telling how something was to be done.

Then another light went out. The place now was in nearly total darkness.
