"'For Heaven's sake, you fellows!' he shouted. 'Look! Blood! You may take it from me there's a corpse in the chimney.'
"A dozen candles invaded the hearth, and a herculean policeman undertook the ascent. In breathless silence the crowd below waited, and, after a few seconds of intense suspense, two helpless legs appeared on the hob. Bit by bit, the rest of the body followed, until, at length, the whole figure of Hartnoll, black, bleeding, bloodstained, was disclosed to view.
"At first it was thought that he was dead; but the surgeon who had hurried to the scene pronouncing him still alive, there arose a tremendous cheer. The murderer had at all events been foiled this time.
"'Begorrah!' cried O'Farroll, 'Hartnoll was after the murderer when he was struck, and shure I'll be after him the same way myself.' And before anyone could prevent him O'Farroll was up the chimney. Up, up, up, until he found himself going down, down, down; and then—bedad—he stepped right out on to the floor of Belton's room.
"'Hulloa!' the latter exclaimed, looking not a bit disconcerted, 'that's a curious mode of making your entrance into my domain! Why didn't you come by the door?'
"'Because,' O'Farroll replied, pointing to a patch of soot near the washstand, 'I followed you. Own up, Dicky Belton. You're the culprit—you did for them all.' And Belton laughed.
"Yes, it was true; overwork had turned Belton's brain, and he was subsequently sent to a Criminal Lunatic Asylum for the rest of his life. But there were moments when he was comparatively sane, and in these interims he confessed everything. Anderson had told him that he was going to hoax the Dean, and filled with indignation at the idea of such a trick being played on a College official—for he, Belton, was a great favourite with the 'Beaks'—he had accompanied Anderson on the plea of helping him, intending, in reality, to frustrate him. It was not till he was in the chimney, crouching behind Anderson, that the thought of killing his fellow-students had entered his mind. The heat of his hiding-place, acting on an already overworked brain, hastened on the madness; and his fingers closing on a clasped knife in one of his pockets, inspired him with a desire to kill.
"The work once begun, he had argued with himself, would have to be continued, and he had then and there decided that all unruly undergraduates should be exterminated.
"With what measure of success this determination was carried out need not be recapitulated here; but with regard to the phantom dog a few words may be added. Since it appeared immediately before the committal of each of the three murders I have just recorded (it was seen by Mr. Kelly before the death of Bob Anderson; by Brady, before the murder of Maguire; and by Hartnoll, before Brady was murdered), I think there can neither be doubts as to its existence nor as to the purport of its visits.
