Norvin Blake dined at his club that evening, returning to his office at about half-past seven. He was relieved to find the place deserted, for he desired an opportunity to think undisturbed. Although this unforeseen twist of events had seemed remarkable, at first, he began to feel that he had been unconsciously waiting for this very hour. Something had always forewarned him that a time would come when he would be forced to take a hand once more in that old affair. Nor was he so much disturbed by the knowledge that Narcone, the butcher, was here in New Orleans as by the memories and regrets which the news aroused.

Entering his private office, he lit the gas, and flinging himself into an easy-chair, gave himself over to recollections of all that the last four years had brought forth. It seemed only yesterday that he had returned from Italy, hot upon the scent which Colonel Neri had uncovered for him. He had been confident, eager, hopeful, yet he had failed, signally, unaccountably. He had combed New York City for a trace of Margherita Ginini with a thoroughness that left no possible means untried. As he looked back upon it now, he wondered if he could ever summon sufficient enthusiasm to attack any other project with a similar determination. He doubted it. Later experience had bred in him a peculiar caution, a shrinking hesitancy at exposing his true feelings, due, no doubt, to that ever-present necessity of watching himself.

Margherita had never written him after her first disappearance; his own letters had been returned from Sicily; the police of New York had failed as those of Rome and Naples and other cities had failed. He had wasted a small fortune in the hire of private detectives. At last, when it was too late to profit him, he had learned that the three women had been in New York at the time of his arrival, but evidently they had become alarmed at his pursuit and fled. It was this which had forced him to give up—the certainty that Margherita knew the motive of his search and resented it. He had never quite recovered from the sting of that discovery, for he was proud, but he had grown too wise to cherish unjust resentment. It merely struck him as a great pity that their lives had fallen out in such unhappy fashion. He never tried to deceive himself into believing that he could forget her, become a new man, and banish the joy and the pain of his past, impartially. There were other women, it is true, who attracted him strongly, aroused his tenderness and appealed to his manhood—and among them Myra Nell Warren. His power of feeling had not been atrophied, rather it had become deeper. Yet his loyalty was never really impaired. In the bottom of his heart he knew that that tawny, slumbrous yet passionate Sicilian girl was his first and his most sacred love.

As he sat alone now, with the evidences of his accomplishment about him, he realized that in spite of his material success, life, so far, at least, had been just as stale and flat as it had promised to be on that night when he and Martel had ridden away from the feast at Terranova. He had made good, to his own satisfaction, in all respects save one, and even in that he had gained the form if not the substance, for the world regarded him as a man of proven courage. It seemed to him a grim and hideous joke, and he wondered what his friends would think if they knew that the very commonplace adventure planned for this evening filled him with a cringing horror. The prospect of this trip into the Italian quarter with the probability of encountering Narcone turned him cold and sick. His hands were like ice and the muscles of his back were twitching nervously; he could feel his heart pound as he let his thoughts have free play. But these symptoms were only too familiar; he had conquered them too many times to think of weakening.

After five years of intimate self-study he was still at a loss to account for his phenomenal cowardice. He wondered again to-night if it might not be the result of a too powerful imagination. Donnelly had no imagination whatever, and the same seemed true of others whom he had studied. As for himself, his fancies took alarm at the slightest hint and went careering off into all the dark byways of supposition, encountering impossible shapes and improbable dangers. Whatever the cause, he had long since given up hope of ever winning a permanent victory over himself and had learned that each trial meant a fresh battle.

When he saw by the clock that the hour of his appointment had come, he arose, although his body seemed to belong to some one else and his spirit was crying out a mad, panicky warning. He opened the drawer of his desk and, extracting a revolver, raised it at arm's-length. He drew it down before his eye until the sights crept into alignment, and held it there for a throbbing second. Then he smiled mirthlessly, for his hand had not shown the slightest tremor.

Donnelly was waiting as Blake walked into headquarters, and, exhuming a box of cigars from the remotest depths of a desk drawer, he offered them, saying:

"I've sent O'Connell over to reconnoiter. There's no use of our starting out until he locates Sabella. You needn't be so suspicious of those perfectos; they won't bite you."

"The last one you gave me did precisely that."

"Must have been one of my cooking cigars. I keep two kinds, one for callers and one for friends."

"Then if this is a Flor de Friendship I'll accept," Blake said with a laugh.

"I see Mr. Dreux didn't change his mind and decide to join us."

"No, this is a little too rough for Bernie. He very cheerfully acknowledged that he was afraid Narcone might recognize me and make trouble."

"I thought of that," Donnelly acknowledged. "Is there any chance?"

In the depths of Blake's consciousness something cried out fearfully in the affirmative, but he replied: "Hardly. He never saw me except indistinctly, and that was nearly five years ago. He might recall my name, but I dare say not without an introduction, which isn't necessary."

"Do you think you will know him?"

"I-I have reason to think I will."

The Chief grunted with satisfaction.

"A funny little fellow, that Dreux!" he remarked. "Wasn't it his father who fought a duel with Colonel Hammond from Baton Rouge?"

"The same. They used shotguns at forty yards. Colonel Hammond was killed."

"Humph! And he was afraid to go with us to-night?"

"Oh, he makes no secret of his cowardice."

"Well, a mule is a mule, a coward is a coward, and a gambler is a—son-of-a-gun," paraphrased the Chief. "If he hasn't any courage he can't force it into himself."

"Do you think so?"

"I know so. I've seen it tried. Some people are born cowards and can't help themselves. As for me, I was never troubled much that way. I suppose you find it the same, too."

"No. My only consolation lies in thinking it's barely possible the other fellow may be as badly frightened as I am."

Donnelly scoffed openly. "I never saw a man stand up better than you. Why I've touted you as the gamest chap I ever saw. Do you remember that dago Misetti who jumped from here into your parish when you were sheriff?"

Blake smiled. "I'm not likely to forget him."

"You walked into a gun that day when you knew he'd use it."

"He didn't, though—at least not much. Perhaps he was as badly rattled as I was."

"Have it your own way," the Chief said. "But that reminds me, he's out again."

"Indeed! I hadn't heard."

"You knew, of course, we couldn't convict him for that killing. We had a perfect case, but the Mafia cleared him. Same old story—perjury, alibis, and jury-fixing. We put him away for resisting an officer, though; they couldn't stop us there. But they've 'sprung' him and he's back in town again. Damn such people! With over two hundred Italian outrages of various kinds in this city up to date, I can count the convictions on the fingers of one hand. The rest of the country is beginning to notice it."

"It is a serious matter," Blake acknowledged, "and it is affecting the business interests of the city. We see that every day."

"If I had a free hand I'd tin-can every dago in New Orleans."

"Nonsense! They're not all bad. The great majority of them are good, industrious, law-abiding people. It's a comparatively small criminal element that does the mischief."

"You think so, eh? Well, if you held down this job for a year you'd be ready to swear they're all blackmailers and murderers. If they're so honest and peaceable, why don't they come out and help us run down the malefactors?"

"That's not their way."

"No, you bet it isn't," Donnelly affirmed. "Things are getting worse every day. The reformers don't have to call my attention to it; I'm wise. So far, they have confined their operations to their own people, but what's to prevent them from spreading out? Some day those Italians will break over and tackle us Americans, and then there will be hell to pay. I'll be blamed for not holding them in check. Why, you've no idea of the completeness of their organization; it has a thousand branches and it takes in some of their very best people. I dare say you think this Mafia is some dago secret society with lodge-rooms and grips and passwords and a picnic once a year. Well, I tell you—"

"You needn't tell me anything about La Mafia," Blake interrupted, gravely. "I know as much about it, perhaps, as you do. Something ought to be done to choke off this flood of European criminal immigration. Believe me, I realize what you are up against, Dan, and I know, as you know, that La Mafia will beat you."

"I'm damned if it will!" exploded the officer. "The policing of this city is under my charge, and if those people want to live here among us—"

The telephone bell rang and Donnelly broke off to answer it.

"Hello! Is that you, O'Connell? Good! Stick around the neighborhood. We'll be right over." He hung up the receiver and explained: "O'Connell has him marked out. We'd better go."

It was not until they were well on their way that Norvin thought to mention the letter, which he had wished to see.

"Oh, yes, I meant to show it to you," said Donnelly.

"But there's nothing unusual about it, except perhaps the signature."

"I thought you said it was anonymous."

"Well, it is; it's merely signed 'One who Knows.'"

"Does it mention an associate of Narcone—a man named Cardi?"

"No. Who's he?"

"I dare say at least a hundred thousand people have asked that same question." Briefly Norvin told what he knew of the reputed chief of the banditti, of the terrors his name inspired in Sicily, and of his supposed connection with the murder of Savigno. "Once or twice a year I hear from Colonel Neri," he added, "but he informs me that Cardi has never returned to the island, so it occurred to me that he too might be in New Orleans."

"It's very likely that he is, and if he was a Capo-Mafia there, he's probably the same here. Lord! I'd like to get inside of that outfit; I'd go through it like a sandstorm."

By this time they had threaded the narrow thoroughfares of the old quarter, and were nearing the vicinity of St. Phillip Street, the heart of what Donnelly called "Dagotown." There was little to distinguish this part of the city from that through which they had come. There were the same dingy, wrinkled houses, with their odd little balconies and ornamental iron galleries overhanging the sidewalks and peering into one another's faces as if to see what their neighbors were up to; the same queer, musty, dusty shops, dozing amid violent foreign odors; the same open doorways and tunnel-like entrances leading to paved courtyards at the rear. The steep roofs were tiled and moss-grown, the pavements were of huge stone flags, set in between seams of mud, and so unevenly placed as to make traffic impossible save by the light of day. Alongside the walks were open sewers, in which the foul and sluggish current was setting not toward, but away from, the river-front. The district was peopled by shadows and mystery; it abounded in strange sights and sounds and smells.

At the corner of Royal and Dumaine they found O'Connell loitering in a doorway, and with a word he directed them to a small cafe and wine-shop in the next block.

A moment later they pushed through swinging doors and entered. Donnelly nodded to the white-haired Italian behind the bar and led the way back to a vacant table against the wall, where he and Norvin seated themselves. There were perhaps a half-dozen similar tables in the room, at some of which men were eating. But it was late for supper, and for the most part the occupants were either drinking or playing cards.

There was a momentary pause in the babble of conversation as the two stalked boldly in, and a score of suspicious glances were leveled at them, for the Chief was well known in the Italian quarter. The proprietor came bustling toward the new-comers with an obsequious smile upon his grizzled features. Taking the end of his apron he wiped the surface of their table dry, at the same time informing Donnelly in broken English that he was honored by the privilege of serving him.

Donnelly ordered a bottle of wine, then drew an envelope from his pocket and began making figures upon it, leaning forward and addressing his companion confidentially, to the complete disregard of his surroundings. Norvin glued his eyes upon the paper, nodding now and then as if in agreement. Although he had taken but one hasty glance around the cafe upon entering, he had seen a certain heavy-muscled Sicilian whose face was only too familiar. It was Narcone, without a doubt. Blake had seen that brutal, lust-coarsened countenance too many times in his dreams to be mistaken, and while his one and only glimpse had been secured in a half-light, his mind at that instant had been so unnaturally sensitized that the photograph remained clear and unfading.

He could feel Narcone staring at him now, as he sat nodding to the senseless patter of the Chief in a sort of breathless, terrifying suspense. Would his own face recall to the fellow's mind that night in the forest of Terranova and set his fears aflame? Blake's reason told him that such a thing was beyond the faintest probability, yet the flesh upon his back was crawling as if in anticipation of a knife-thrust. Nevertheless, he lit a cigar and held the match between fingers which did not tremble. He was fighting his usual, senseless battle, and he was winning. When the proprietor set the bottle in front of him he filled both glasses with a firm hand and then, still listening to Donnelly's words, he settled back in his chair and let his eyes rove casually over the room. He encountered Narcone's evil gaze when the glass was half-way to his lips and returned it boldly for an instant. It filled him with an odd satisfaction to note that not a ripple disturbed the red surface of the wine.

"Have you 'made' him?" Donnelly inquired under his breath.

Blake nodded: "The tall fellow at the third table."

"That's him, all right," agreed the Chief. "He doesn't remember you."

"I didn't expect him to; I've changed considerably, and besides he never saw me distinctly, as I told you before."

"You've got the policeman's eye," declared Donnelly with enthusiasm. "I wanted you to pick him out by yourself. We'll go, now, as soon as we lap up this dago vinegar."

Out in the street again, Blake heaved a sigh of relief, for even this little harmless adventure had been a trial to his unruly nerves.

"We'll drift past the Red Wing Club; it's a hang-out of mine and I want to talk further with you," said Donnelly.

They turned back towards the heart of the city, stopping a moment while the Chief directed O'Connell to keep a close watch upon Narcone.

The Red Wing Club was not really a club at all, but a small restaurant which had become known for certain of its culinary specialties and had gathered to itself a somewhat select clientele of bons vivants, who dined there after the leisurely continental fashion. Thither the two men betook themselves.

"I can't see what real good those extradition papers are going to do you, even now that you're sure of your man," said Norvin as soon as they were seated. "It won't be difficult to arrest him, but to extradite him will prove quite another matter. I'm not eager myself to take the stand against him, for obvious reasons." Donnelly nodded his appreciation. "I will do so, if necessary, of course, but my evidence won't counterbalance all the testimony Sabella will be able to bring. We know he's the man; his friends know it, but they'll unite to swear he is really Vito Sabella, a gentle, sweet soul whom they knew in Sicily, and they'll prove he was here in America at the time Martel Savigno was murdered. If we had him in New York, away from his friends, it would be different; he'd go back to Sicily, and once there he'd hang, as he deserves."

Donnelly swore under his breath. "It's the thing I run foul of every time I try to enforce the law against these people. But just the same I'm going to get this fellow, somehow, for he's one of the gang that fired into the Pallozzos and killed Tony Alto. That's another thing I know but can't prove. What made you ask if that letter was written by a woman? Has Sabella a sweetheart?"

"Not to my knowledge. I—" Norvin hesitated. "No, Sabella has no sweetheart, but Savigno had. I haven't told you much of that part of my story. It's no use my trying to give you an idea of what kind of woman the Countess of Terranova was, or is—you wouldn't understand. It's enough to say that she is a woman of extraordinary character, wholly devoted to Martel's memory, and Sicilian to the backbone. After her lover's death, when the police had failed, she swore to be avenged upon his murderers. I know it sounds strange, but it didn't seem so strange to me then. I tried to reason with her, but it was a waste of breath. When I returned to Sicily after my mother died, Margherita—the Countess—had disappeared. I tried every means to find her—you know, Martel left her, in a way, under my care—but I couldn't locate her in any Italian city. Then I learned that she had come to the United States and took up the search on this side. It's a long story; the gist of it is simply that I looked up every possibility, and finally gave up in despair. That was more than four years ago. I have no idea that all this has any connection with our present problem."

Donnelly listened with interest, and for a time plied Blake with shrewd questions, but at length the subject seemed to lose its importance in his mind.

"It's a queer coincidence," he said. "But the letter was mailed in this city and by some one familiar with Narcone's movements up to date. If your Countess was here you'd surely know it. This isn't New York. Besides, women don't make good detectives; they get discouraged. I dare say she went back to Italy long ago and is married now, with a dozen or more little counts and countesses around her."

"I agree with you," said Blake, "that she can't be the 'One Who Knows.' There are too many easier explanations, and I couldn't hope—" He checked himself. "Well, I guess I've told you about all I know. Call on me at any time that I can be of assistance."

He left rather abruptly, struggling with a sense of self-disgust in that he had been led to talk of Margherita unnecessarily, yet with a curious undercurrent of excitement running through his mood.
