Roath's examination, on this day, did not disappoint the general expectation. Although somewhat paler than ordinary, he was thoroughly self-possessed; his answers were clear and to the point; not once did his memory play him false; scarcely once did he hesitate for a word. He gave evidence not only of close study, but of careful analysis, and profound, sagacious thought. But he looked worn when it was over, as if the mental strain had been severe; and seemed scarcely to hear the comments and congratulations showered upon him.

Into the midst of these burst Trubie, with the old question, "Have you seen anything of Arling?" and hardly waiting for the general "No" which answered it, upstairs he rushed, three steps at a time, to the room of his friend. The stream of talk had scarcely resumed its flow, ere he was back again, with a hurried step, and a perturbed face.

"It's odd about Arling," he began, abruptly. "I can't get any answer, and there's nothing stirring in the room. But I looked into the keyhole, and the key is certainly inside."

Some few of the students, startled by his words, and the deep gravity of his look, gathered around him to discuss the matter, when a stout, gray-haired professor came out from the examination room.

"Good day, Mr. Trubie," said he, as he passed the group. "I hope your patient is doing well."

"I—I don't know, sir," faltered Trubie; "I have not seen him since yesterday, at dusk. And he is unaccountably missing this morning;—at least, I thought he must be out when I went to his room, at eight o'clock, and couldn't get in. But I have just been up again, and—and the door is certainly locked on the inside."

Being already in possession of the main facts of the case,—namely, that Alec Arling, one of the class of medical students now undergoing examination for their degree, had been suffering for some days from severe and increasing intestinal trouble, and had been advised by the faculty to keep his room for a day or two, under the care of his friend, Frank Trubie;—the professor now, by means of a few rapid questions, elicited the additional facts, that Trubie had been suddenly called away, on the previous evening, by family affliction, to his home in a near suburb, and had spent the night there, and that Edmund Roath, who had volunteered to keep a little watch over the sick-room during his absence, had remained with Arling till past midnight, engaged in comparing notes of clinical lectures, and in psychological talk (with which matters Arling would busy himself, in spite of remonstrance), and had then left him, recommending him to go to sleep at once, and had heard the door duly locked on his exit. Roath further stated that, in consequence of this protracted sitting, and previous hard work, he had slept late this morning; and, taking it for granted that Trubie, according to promise, was already back at his post, he had seated himself at his books, immediately upon rising. Very shortly after, Trubie had appeared, and informed him that Arling had gone out, whereat he had been considerably surprised,—not that the young man was unable to leave his room, but because it was inexpedient to do so. Nevertheless, he frankly acknowledged that his mind was too much preoccupied to give more than a passing thought to the matter, especially as he knew well that any remissness on his part was sure to be amply atoned for by Trubie,—he and Arling being, as everybody knew, the Damon and Pythias of the class.

The professor was a man of few words, quick conclusions, and prompt action. "There is but one way of getting at the bottom of the matter," said he, at the end of this rapid statement. "Let somebody bring a crowbar, and pry open the door."

Scarce sooner said than done. The door yielded easily to the rude implement, in Trubie's impetuous hands, and was followed by a rush of the assembled students toward the opening,—though, even in this moment of eager curiosity, the instinct of subordination allowed the professor to in first. He went straight to the bed, where was seen a human form, lying on its side, in an easy attitude of slumber. He bent for a moment above this form, while a sudden silence fell upon the startled spectators,—he touched the brow, lifted the hand, and then, turning slowly round, said, in deep, serious tones;—

"He is dead."
