Some quality of unexpressed insistence in the stranger—or was it the speaker's own uneasiness of spirit?—brought back the roving, brilliant eyes to the square face below.
"A little blackmail on the side, eh?"
The words were spoken low, but with a peculiar, abrupt crispness. This, then, was direct challenge. Professor Certain tautened. Should he accept it, or was it safer to ignore this pestilent disturber? Craft and anger thrust opposing counsels upon him. But determination of the issue came from outside.
"Lemme through."
From the outskirts of the crowd a rawboned giant forced his way inward. He was gaunt and unkempt as a weed in winter.
"Here's trouble," remarked a man at the front. "Allus comes with a Hardscrabbler."
"What's a Hardscrabbler?" queried the well-dressed man.
"Feller from the Hardscrabble Settlement over on Corsica Lake. Tough lot, they are. Make their own laws, when they want any; run their place to suit themselves. Ain't much they ain't up to. Hoss-stealin', barn-burnin', boot-leggin', an' murder thrown in when—"
"Be you the doctor was to Corsica Village two years ago?" The newcomer's high, droning voice cut short the explanation.
"I was there, my friend. Testimonials and letters from some of your leading citizens attest the work—"
"You give my woman morpheean." There was a hideous edged intonation in the word, like the whine of some plaintive and dangerous animal.
"My friend!" The Professor's hand went forth in repressive deprecation. "We physicians give what seems to us best, in these cases."
"A reg'lar doctor from Burnham seen her," pursued the Hardscrabbler, in the same thin wail, moving nearer, but not again raising his eyes to the other's face. Instead, his gaze seemed fixed upon the man's shining expanse of waistcoat. "He said you doped her with the morpheean you give her."
"So your chickens come home to roost, Professor," said the stranger, in a half-voice.
"Impossible," declared the Professor, addressing the Hardscrabbler. "You misunderstood him."
"They took my woman away. They took her to the 'sylum."
Foreboding peril, the people nearest the uncouth visitor had drawn away. Only the stranger held his ground; more than held it, indeed, for he edged almost imperceptibly nearer. He had noticed a fleck of red on the matted beard, where the lip had been bitten into. Also he saw that the Professor, whose gaze had so timorously shifted from his, was intent, recognizing danger; intent, and unafraid before the threat.
"She used to cry fer it, my woman. Cry fer the morpheean like a baby." He sagged a step forward. "She don't haff to cry no more. She's dead."
Whence had the knife leapt, to gleam so viciously in his hand? Almost as swiftly as it was drawn, the healer had snatched one of the heavy torch-poles from its socket. Almost, not quite. The fury leapt and struck; struck for that shining waistcoat, upon which his regard had concentrated, with an upward lunge, the most surely deadly blow known to the knife-fighter. Two other movements coincided, to the instant. From the curtain of cheesecloth the slight form of a boy shot upward, with brandished arms; and the square-built man reached the Hardscrabbler's jaw with a powerful and accurate swing. There was a scream of pain, a roar from the crowd, and an answering bellow from the quack in midair, for he had launched his formidable bulk over the rail, to plunge, a crushing weight, upon the would-be murderer, who lay stunned on the grass. For a moment the avenger ground him, with knees and fists; then was up and back on the platform. Already the city man had gained the flooring, and was bending above the child. There was a sprinkle of blood on the bright, rough boards.
"Oh, my God! Boy-ee! Has he killed you?"
"No: he isn't killed," said the stranger curtly. "Keep the people back. Lift down that torch."
The Professor wavered on his legs, grasping at the rail for support.
"You are a doctor?" he gasped.
"Yes."
"Can you save him? Any money—"
"Set the torch here."
"Oh, Boyee, Boyee!" The great, dark man had dropped to his knees, his face a mask of agony.
"Oh, the devil!" said the physician disgustedly. "You're no help. Clear a way there, some of you, so that I can get him to the hotel." Then, to the other. "Keep quiet. There's no danger. Only a flesh wound, but he's fainted."
Carefully he swung the small form to his shoulder, and forced a way through the crowd, the little girl, who had followed him to the platform, composedly trotting along in his wake, while the Hardscrabbler, moaning from the pain of two broken ribs, was led away by a constable. Some distance behind, the itinerant wallowed like a drunken man, muttering brilliant bargain offers of good conduct to Almighty God, if "Boyee" were saved to him.
Once in the little hotel room, the physician went about his business with swift decisiveness, aided by the mite of a girl, who seemed to know by instinct where to be and what to do in the way of handling towels, wash-basin, and the other simple paraphernalia required. Professor Certain was unceremoniously packed off to the drug store for bandages. When he returned the patient had recovered consciousness.
"Where's Dad?" he asked eagerly. "Did he hurt Dad?"
"No, Boyee." The big man was at the bedside in two long, velvety-footed steps. Struck by the extenuation of the final "y" in the term, the physician for the first time noted a very faint foreign accent, the merest echo of some alien tongue. "Are you in pain, Boyee?"
"Not very much. It doesn't matter. Why did he want to kill you?"
"Never mind that, now," interrupted the physician. "We'll get that scratch bound up, and then, young man, you'll go to sleep."
Pallid as a ghost, the itinerant held the little hand during the process of binding the wound. "Boyee" essayed to smile, at the end, and closed his eyes.
"Now we can leave him," said the physician. "Poppet, curl up in that chair and keep watch on our patient while this gentleman and I have a little talk in the outer room."
With a brisk nod of obedience and comprehension, the elfin girl took her place, while the two men went out.
"What do I owe you?" asked Professor Certain, as soon as the door had closed.
"Nothing."
"Oh, that won't do."
"It will have to do."
"Courtesy of the profession? But—"
The other laughed grimly, cutting him short. "So you call yourself an M.D., do you?"
"Call myself? I am. Regular degree from the Dayton Medical College." He sleeked down his heavy hair with a complacent hand.
The physician snorted. "A diploma-mill. What did you pay for your M.D.?"
"One hundred dollars, and it's as good as your four-year P. and S. course or any other, for my purposes," retorted the other, with hardihood. "What's more, I'm a member of the American Academy of Surgeons, with a special diploma from St. Luke's Hospital of Niles, Michigan, and a certificate of fellowship in the National Medical Scientific Fraternity. Pleased to meet a brother practitioner." The sneer was as palpable as it was cynical.
"You've got all the fake trimmings, haven't you? Do those
