the final syllable of the long ones.

"Mistair Heath," he said, "I saw-a your affectionate par-ting weez Mees Warriner."

Gerald had just then the mind of a culprit, and he began to explain apologetically: "It was cowardly in me to insult a defenseless girl. She didn't invite it. I am ashamed of myself."

He hardly realized to whom he was speaking. The two men were now walking rapidly, Ravelli taking two strides to one of the bigger Gerald, in order to keep alongside.

"You-a should be ashamed—you-a scoundrel."

As much of jealous fury and venomous malice as could be vocalized in six words was in Ravelli's sudden outbreak. Gerald was astounded. He turned upon his companion, caught him by both lapels of the coat, and shook him so violently that his boot-soles pounded the ground. Ravelli staggered back upon being loosed, and threw one arm around a tree to steady himself.

"I didn't mean to hurt you," said Gerald, "but you shouldn't be reckless with your language. Perhaps you don't know what scoundrel means in English."

"I saw you-a kiss her hands."

"Did you? Well, do you know what I'd do to you, Ravelli, if I saw you kiss her hands—as I did—without her consent? I'd wring your miserable neck. Now, what are you going to do to me?"

"I am-a going to keel you!"

The blade of a knife flashed in Ravelli's right hand, as he made a furious onslaught; but the stronger and quicker man gripped both of his assailant's wrists, threw him violently to the ground, and tortured him with wrenches and doublings until he had to drop the weapon. In the encounter the clothes of both men were torn, and when Ravelli regained his feet blood was dripping from his hand. The blade had cut it.

"You meant to kill me," Gerald exclaimed.

"I said-a so," was the sullen, menacing response.

"And with my own knife!" and Gerald, picking up the knife, recognized it.

"Your own knife—ze one zat you carve-a Mary's hand with so lovingly."

Ravelli had retained it since the previous afternoon, when he had picked it up from Mary Warriner's desk. Its blade was now red with blood, as Gerald shut and pocketed it.

"You cowardly murderer!"

"Murderer? Not-a yet. But I meant to be."

Ravelli turned off by the cross-path, and Gerald passed on.

CHAPTER III.

The first man to go to work at Overlook in the morning was Jim Wilson, because he had to rouse the fire under a boiler early enough to provide steam for a score of rock drills. The night watchman awakened him at daybreak, according to custom, and then got into a bunk as the other got out of one.

"Everything all right?" Jim asked.

"I guess so," the other replied. "But I hain't seen your boiler sence before midnight. Eph was disturbin' Mary Mite, and so I hung 'round her cabin pretty much the last half of the night."

Jim went to his post at the boiler, and at an unaccustomed pace, from the point where he first saw and heard steam hissing upward from the safety valve. On quitting the night previous, he had banked the fire as usual, and this morning he should have found it burning so slowly that an hour of raking, replenishing, and open draughts would no more than start the machinery at seven o'clock. Going nearer he found that open dampers and a fresh supply of coal had set the furnace raging.

What was that which protruded from the open door, and so nearly filled the aperture that the draught was not impaired?

A glance gave the answer. It was the legs and half the body of a man, whose head and shoulders were thoroughly charred, as Jim was horrified to see when he pulled the remains out upon the ground.

Jim ran to tell the superintendent, and within a few minutes a knot of excited men surrounded the body. The gathering grew in numbers rapidly. By means of the clothing the dead and partially burned man was identified at once as Tonio Ravelli. That he had been murdered was an equally easy conclusion. The murderer had apparently sought to cremate the corpse. Whether he had found it physically impossible, or had been frightened away, could only be conjectured.

"Who can have done it?" was the question asked by Superintendent Brainerd, the autocrat of Overlook.

There was a minute of silence, with all staring intently at the body, as though half expecting it to somehow disclose the truth. The night watchman was first to speak.

"Eph might have done it," he said.

Then he told of the monomaniac's visit to the telegraph station, and of the acute stage which his malady had reached. Nobody else present had seen him since the previous evening. Superintendent Brainerd ordered a search of the lodgings. Ten minutes were sufficient for a round of the different quarters. Eph was in none of them. The searchers returned to the furnace, and with them came Gerald Heath.

"I met Eph yonder where the paths cross, not a hundred yards from here, a little past midnight," Gerald said. "He was terribly excited. That was after he had tried in vain to telegraph a crazy message. Evidently his delusion, that his whole life was condensed into a brief space, had driven him to a frenzy. He spoke of walking to Dimmersville, but I tried to quiet him, and he disappeared."

Dimmersville was a town about ten miles distant, in a direction opposite to that from which the railroad had worked its way through the mountains. No wire connected it with Overlook, and there was no public road for the nearest third of the way, although a faint trail showed the course that a few persons had taken on foot or horseback.

"Very likely Eph has gone toward Dimmersville," Brainerd argued, "and we must try to catch him."

Before the order could be specifically given a horse and a rider arose over the edge of the level ground and came into the midst of the assemblage. The man in the saddle had a professional aspect, imparted chiefly by his smoothly shaven face. In this era of mustaches a hairless visage is apt to be assigned to a clergyman, who shaves thus from a motive of propriety; an actor, who does it from necessity; or somebody who aims at facial distinction without the features suitable to that purpose. A countenance of which it can only be said that it has one nose, one mouth, and two eyes, all placed in expressive nonentity, and which is dominated utterly by hair on and around it, may be less lost to individuality if entirely shaven. Of such seemed the visage of the dark man, who calmly rode into the excitement at Overlook.

"Which way have you come?" Brainerd asked.

"From Dimmersville," was the reply.

"Did you see anybody on the way?"

"I started very early. Folks were not out of their beds in the houses—as long as there were any houses—and that is only for five or six miles, you know. After that—yes—I did see one man. A curiously excited chap. He looked tired out. He asked the distance to Dimmersville, and whether the telegraph office would be open by the time he got there. Then he skurried on before I'd half answered him."

All that was known of the murder was told to the stranger by half a dozen glib tongues, and it was explained to him that he had encountered the maniacal fugitive.

"I knew there was something wrong about him," said the stranger. "It is my business to be observant."

He dismounted and hitched his horse to a tree. The dead body was shown to him. He examined it very thoroughly. All the particulars were related to him over and over. Then he drew Superintendent Brainerd aside.

"My name is Terence O'Reagan," he said, and in his voice was faintly distinguishable the brogue of the land whence the O'Reagans came. "I am a government detective. I have been sent to work up evidence in the case of some Italian counterfeiters. We had a clew pointing to a sub-contractor here—the very man who lies there dead. Our information was that he used some of the bogus bills in paying off his gang. Now, it isn't going outside my mission to investigate
