On his way to Brownsville the next morning Dave found himself still somewhat dazed by his sudden happiness; the more he thought of it the more wonderful it seemed. During the day he went through his court duties like a man in a trance. Such joy as this was unbelievable; he felt as if he must tell the world about it. He well understood Alaire's repugnance to divorce, but he was sure that he could overcome it, if indeed her own truer understanding of herself did not relieve him of that necessity; for at this moment his desires were of a heat sufficient to burn away all obstacles, no matter how solid. It seemed, therefore, that the future was all sunshine.

He had no opportunity of speaking with Judge Ellsworth until court adjourned. Then the judge took him by the arm, with that peculiarly flattering assumption of intimacy of which he was master, and led the way toward his office, inquiring meanwhile for news of Jonesville. Dave's high spirits surprised him and finally impelled him to ask the cause. When Dave hinted unmistakably at the truth, Ellsworth exclaimed, with a sharp stare of curiosity:

"See here! You haven't forgotten what I told you that night on the train?"

"What? Yes, I had forgotten."

"You promised to tell me if you thought seriously about marriage."

"Very well, then; I'm telling you now."

"Do you mean that, Dave?"

"Of course I do. But don't look at me as if I'd confessed to arson or burglary. Listen, Judge! If you have good taste in jewelry, I'll let you help me select the ring."

But Judge Ellsworth continued to stare, and then muttered uncertainly:
"You're such a joker—"

Dave assumed a show of irony. "Your congratulations overwhelm me. You look as if you were about to begin the reading of the will."

"I want to hear about this right away." Ellsworth smiled faintly. "Can you come to my office tonight, where we can be alone?"

Dave agreed to the appointment and went his way with a feeling of amusement. Old folks are usually curious, he reflected; and they are prone to presume upon the privileges that go with age. In this instance, however, it might be well to make a clean breast of the affair, since Ellsworth was Alaire's attorney, and would doubtless be selected to secure her divorce.

The judge was waiting when Dave called after supper, but for some time he maintained a flow of conversation relating to other things than the one they had met to discuss. At last, however, he appeared to summon his determination; he cleared his throat and settled himself in his chair—premonitory signs unusual in a man of Ellsworth's poise and self-assurance.

"I reckon you think I'm trying to mix up in something that doesn't concern me," he began; "and perhaps I am. Maybe you'll make me wish I'd minded my own business—that's what usually happens. I remember once, out of pure chivalry, trying to stop a fellow from beating his wife. Of course they both turned on me—as they always do. I went to the hospital for a week, and lost a profitable divorce case. However, we try to do our duty as we see it."

This was anything but a promising preamble; Dave wondered, too, at his friend's obvious nervousness.

"So you've found the girl, eh?" the judge went on.

"Yes."

"Are you accepted? I mean, have you asked her to marry you?"

"Of course I have. That's about the first thing a fellow does."

Ellsworth shuffled the papers on his desk with an abstracted gaze, then said, slowly, "Dave—I don't think you ought to marry."

"So you told me once before. I suppose you mean I'm poor and a failure."

"Oh no! All men are failures until they marry. I'm thinking of what marriage means; of the new duties it brings, of the man's duty to himself, to the woman, and to society; I'm thinking of what lies inside of the man himself."

"Um-m! That's pretty vague."

"I've studied you a long time, Dave, and with a reason. I've studied heredity, too, and—you mustn't marry."

Law stirred in his chair and smiled whimsically. "I've done some studying along those lines, too, and I reckon I know myself pretty well. I've the usual faults, but—"

Ellsworth interrupted. "You don't know yourself at all, my boy. There's just the trouble. I'm the only man—living man, that is—who knows you." For the first time he looked directly at his caller, and now his lids were lifted until the eyes peered out bright, hard, and piercing; something in his face startled Dave. "I was your father's attorney and his friend. I know how he lived and how he died. I know—what killed him?"

"You mean, don't you, that you know who killed him?"

"I mean just what I say."

Dave leaned forward, studying the speaker curiously. "Well, come through. What's on your mind?" he demanded, finally.

"The Guadalupes had to kill him, Dave."

"Had to? HAD to? Why?"

"Don't you know? Don't you know anything about your family history?"
Dave shook his head. "Well, then—he was insane."

"Insane?"

"Yes; violently."

"Really, I—Why—I suppose you know what you're talking about, but it sounds incredible."

"Yes, it must to you—especially since you never knew the facts. Very few people did know then, even at the time, for there were no newspapers in that part of Mexico; you, of course, were a boy at school in the United States. Nevertheless, it's true. That part of the story which I didn't know at the time I learned by talking with General Guadalupe and others. It was very shocking."

Dave's face was a study; his color had lessened slightly; he wet his lips. "This is news, of course," said he, "but it doesn't explain my mother's death. Who killed her, if not the Guadalupes?"

"Can't you guess? That's what I meant when I said they had to kill Frank Law." Ellsworth maintained his fixity of gaze, and when Dave started he nodded his head. "It's God's truth. The details were too—dreadful. Your father turned his hand against the woman he loved and—died a wife-killer. The Guadalupes had to destroy him like a mad dog. I'm sorry you had to learn the truth from me, my boy, but it seems necessary that I tell you. When I knew Frank Law he was like any other man, quick-tempered, a little too violent, perhaps, but apparently as sane as you or I, and yet the thing was there."

Dave rose from his chair and bent over the desk. "So THAT'S what you've been driving at," he gasped. "That's what you meant when you said I shouldn't marry." He began to tremble now; his voice became hoarse with fury. "Now I understand. You're trying to tell me that—maybe I've got it in me, eh? Hell! YOU'RE crazy, not I. I'm all right. I reckon I know."

"HE didn't know," Ellsworth said, quietly. "I doubt if he even suspected."

Dave struck the desk violently with his clenched fist. "Bosh! You're hipped on this heredity subject. Crazy! Why, you doddering old fool—" With an effort he calmed himself, realizing that he had shouted his last words. He turned away and made a circuit of the room before returning to face his friend. "I didn't mean to speak to you like that, Judge. You pulled this on me too suddenly, and I'm—upset. But it merely proves my own contention that I'm not Frank Law's son at all. I've always known it."

"How do you know it?"

"Don't you suppose I can tell?" In spite of himself Dave's voice rose again, but it was plain from the lawyer's expression that to a man of his training no mere conviction unsupported by proof had weight. This skepticism merely kept Dave's impatience at a white heat. "Very well, then," he argued, angrily, "let's say that I'm wrong and you're right. Let's agree that I am his son. What of it? What makes you think I've inherited—the damned thing? It isn't a disease. Me, insane? Rot!" He laughed harshly, took another uncertain turn around the room, then sank into his chair and buried his face in his hands.

Ellsworth was more keenly distressed than his hearer imagined; when next he spoke his voice was unusually gentle. "It IS a disease, Dave, or worse, and there's no way of proving that you haven't inherited it. If there is the remotest possibility that you have—if you have the least cause to suspect—why, you couldn't marry and—bring children into the world, now could you? Ask yourself if you've shown any signs—?"

"Oh, I know what you mean. You've always said I go crazy when I'm—angry. Well, that's true. But it's nothing more than a villainous temper. I'm all right again afterward."

"I wasn't thinking so much of that. But are you sure it's altogether temper?" the judge insisted. "You don't merely lose control of yourself; you've told me more than once that you go completely out of your mind; that you see red and want to kill and—"

"Don't you?"

"I never felt the slightest desire to destroy, no matter how angry I chanced to be. I've always asserted that murderers, homicides, suicides, were irresponsible; that they were sick here." Ellsworth touched his forehead. "I can't see how any sane man can take his own or another's life, no matter what the provocation. But I'm not a doctor, and that's an extreme view, I know. Anyhow, you'll agree that if you have Frank Law's blood in your veins it won't do to marry."

"I haven't got it," the younger man groaned, his gaze turned sullenly downward. "Even granting that I have, that's no sign I'd ever—run amuck the way he did."

"You told me just now that you don't know your family history?"

"Yes. What little I've heard isn't very pretty nor very much to the family's credit. They were a bad lot, I believe."

"Frank Law had two brothers and a sister, had he not?"

"Yes. One of my uncles was a tough hombre. I'm told he notched his gun pretty well."

"He was about the worst man of his day. He was shot in Dodge City on one of his rampages."

Dave raised shocked and curious eyes. "You think he was crazy?"

"Most of those old-time gunmen would be so considered nowadays. Some unbelievable stories are told about that uncle of yours. The other one disappeared mysteriously."

"I believe so. He just walked away from his wife and family and business one day and was never heard of again."

Ellsworth seemed to consider this admission significant. "Now the sister, your aunt?"

"I think she's somewhere in the East; I never saw her."

"She is; she's an inmate of an institution the name and address of which I have here." Ellsworth thrust his finger into the loose pile of documents before him. Avoiding his caller's eyes he continued: "You can't very well ignore such a family history, Dave. I've never traced it back beyond the last generation, but you probably could if you tried."

In a voice hardly his own, Dave articulated: "God! This is—hideous."

"It is. I'd like to believe that you don't belong to the Laws, but I can't put much faith in that childhood fancy of yours. Run it down; convince yourself. But first go to the girl, whoever she is, and tell her the facts. If she's the right sort—"

"No, no!" The words were wrung from Dave's lips. "She knows too well how heredity acts; she's had one experience."

"Eh? You say she knows—Who is she, Dave? Don't tell me you mean—Alaire?"

Dave nodded.

"Damnation!" Ellsworth leaped to his feet and, striding around the desk, seized his caller roughly by the shoulder. "What are you telling me? Good God, Alaire! A married woman! So you—cut under Ed Austin, eh?" Momentarily Ellsworth lost control of himself; his eyes blazed and his fingers tightened painfully. "What damnable trick have you played on that girl? Tell me before I choke you."

For once Dave Law's passion failed to ignite at the heat of another's anger; he only sat limp and helpless in the judge's grasp. Finally he muttered: "I played square enough. It's one of those things that just happen. We couldn't help ourselves. She'll come to you for her divorce."

The lawyer uttered a shocking oath. "Then it's no mere romantic infatuation on her part?"

"Oh no!"

Ellsworth loosed his grip. He turned away and began to pace the office floor, shaking his head. "This is—unfortunate. Alaire, of all people—as if she didn't have enough to bear." He turned fiercely upon the cowering figure in the chair, saying: "I'll tell her the whole truth myself, before she goes any further."

"No! Oh, please! Let me, in my own way." Dave writhed and sank his face in his hands once more. After a while he said, "I'm waiting for you to tell me it's all a nightmare."

"Humph!" The judge continued his restless pacing. "I was sorry for you when you came in here, and it took all my strength to tell you; but now you don't matter at all. I was prepared to have you go ahead against my advice, but—I'll see you damned first."

"You have damned me."

When Ellsworth saw the haggard face turned to his he ceased his walk abruptly. "I'm all broken up, Dave," he confessed in a gentler tone than he had used heretofore. "But you'll thank me some day."

Law was no longer the big, strong, confident fellow who had entered the office such a short time before. He had collapsed; he seemed to have shrunk; he was pitifully appealing. Although there were many things he would have said, many questions upon his tongue, he could not voice them now, and it was with extreme difficulty that he managed to follow the judge's words at all.

After a time he rose and shook Ellsworth's hand limply, mechanically; then he shambled out of the office. Like a sick man, he stumbled down the stairs and into the street. When he entered his hotel the clerk and some of the idlers in the lobby looked at him queerly, but he did not see them.

All that night Dave walked the floor of his room or sat hunched up on the edge of his bed, staring at the wall and fighting the fears that preyed upon him.

He had faith enough in Alaire to believe that she would marry him regardless of the facts; her kiss, that one delirious moment when he had held her to his breast, had taught him much, and it was, in fact, this very certainty which made his struggle so hard. After all, why not? he asked himself a thousand times. Ellsworth's fears were surely exaggerated. Who could say that Frank Law had passed on his heritage? There was at least a chance that he had not, and it would require more than a remote possibility, more evidence than Ellsworth could summon, to dismay Alaire. Suppose it should transpire that he was somehow defective? What then? The signs of his mental failing would give ample warning. He could watch himself carefully and study his symptoms. He could lead the life of a sentinel perpetually on guard. The thing might never come—or at the worst it probably would not manifest itself until he was further along in years. That, it seemed, was the family history, and in such a case Dave was assured of half a life at least. Ellsworth was altogether too fearful. Yes, and he was too officious by far. This was something that did not concern him.

But such reasoning naturally brought little comfort. Dave's fears would not be put down. In common with most men of splendid physique, he had a vague contempt for those less perfect; disease or deformity had never failed to awaken his pity, and he had often argued that defective human beings, like unhealthy stock, should not be allowed to mate and to perpetuate their weaknesses. This eugenic conviction had helped to ease his conscience somewhat during his acquaintance with Alaire, for he had told himself that Ed Austin, by reason of his inherited vices, had sacrificed all right to love and marriage. These thoughts came home now to roost. What was Ed's evil heritage compared to his own? It was as vinegar to vitriol.

And yet shining through all Dave's distress, like a faint, flickering beacon in a storm, was that old doubt of his parentage; and to this he finally began to pin his hopes. In the day or two that followed his interview with Ellsworth, it afforded him almost the only comfort he knew; for in the end he had to face the truth; he could not marry if he were really Frank Law's son.

Those were dark hours for Dave. He discharged his duties automatically, taking no interest whatever in his work; his nights he spent in morose meditation. Unable to sleep, he tramped the hot streets in an effort to fight off his growing nervousness. He became irritable, despondent; his eyes took on the look of an invalid's; his face aged and grayed. Physically, too, he grew very tired, for no burden is heavier to bear than that of doubt and indecision.

One afternoon Ellsworth entered his office to find Dave waiting for him. The young man began in a shaky, husky voice:

"I can't stand it, Judge. I'm going to pieces, fast."

"You do look bad."

"Yes. I don't sleep. I'm so irritable I can't get along up at the courthouse. I'm licked. The worst of it is, I don't know whether it's all imagination, or whether you really stirred up that devilish sleeping thing in me. Anyhow, something has got me. All I can do is study and analyze and watch and imagine—I sit all night thinking—thinking, until everything gets queer and distorted. If I were sane before, you've about unbalanced me with your damnable suggestions."

"A few nights of sleep will make you feel better," Ellsworth said, gravely.

"I tried drugs, but they made me worse. God! Then my fancies WERE sick.
No, I'm going to get out."

"Where? How?"

"I'm going north to look up the members of my family and learn who I really am. I resigned from the Ranger force to-day. That's no place for a fellow with a—homicidal mania."

"Dave! You're taking this thing too absolutely and too hard," Ellsworth declared.

But Dave went on, unheeding. "Another reason why I want to get away now is that Alaire will expect me to come to her when she sends for me and—I wouldn't dare trust myself."

"Have you told her—written her?"

"Not yet, and I sha'n't until I trace out the last doubt in my own mind."

In an effort to cheer, Ellsworth put his arm about the sufferer's shoulders. "I'm sure you'll do the right thing, Dave," he said. "Maybe, after all, your instinct is true and you're not Frank Law's boy. I hope so, for this thing weighs me down as it weighs you; but you mustn't let it whip you. Don't give in, and meanwhile, above all things, try to get some sleep."

Dave nodded and mumbled something; then he slouched out, leaving the lawyer overcome by a great pity. Ellsworth had seen men, stunned by a court sentence, turn away from the bar with that same dumb, fixed look of hopelessness in their eyes. Impulsively he cursed the sense of duty that had prompted him to interfere.
