“Oh, a perfect fever of excitement, of course; for it now became evident that a crime had been committed in both instances; and the Press made a great to-do over it. Within the course of the next fortnight it was positively frothing, throwing panic into the public mind by the wholesale, and whipping up people’s fears like a madman stirring a salad; for, by that time a third body had been found—under some furze bushes, upward of half a mile distant from where the second had been discovered. Like the first body, this one was wearing night clothes; but it was in an even more advanced state of decomposition than the second, showing that the man must have died long before either of them!”

“Oho!” said Cleek, with a strong rising inflection. “What a blundering idiot! Our assassin is evidently a raw hand at the game, Mr. Narkom, and not, as I had begun to fancy, either a professional or the appointed agent of some secret society following a process of extermination against certain marked men. Neither the secret agent nor the professional bandit would be guilty of the extreme folly of operating several times in the same locality, be assured; and here is this muddling amateur letting himself be lulled into a feeling of security by the failure of anybody to discover the bodies of the first victims, and then going at it again in the same place and the same way. For it is fair to assume, I daresay, that the fourth man was discovered under precisely similar circumstances to the first.”

“Not exactly—very like them, but not exactly like them, Cleek. As a matter of fact, he was alive when found. I didn’t credit the report when I first heard it (a newspaper man brought it to me), and sent Petrie to investigate the truth of it.”

“Why didn’t you believe the report?”

“Because it seemed so wildly improbable. And, besides, they had hatched up so many yarns, those newspaper reporters, since the affair began. According to this fellow, a tramp, crossing the heath in quest of a place to sleep, had been frightened half out of his wits by hearing a voice which he described as being like the voice of some one strangling, calling out in the darkness, ‘Sapphires! Sapphires!’ and a few moments later, when, as the reporter said, the tramp told him, he was scuttling away in a panic, he came suddenly upon the figure of a man who was dancing round and round like a whirling dervish, with his mouth wide open, his tongue hanging out, and the forefinger of each hand stuck in his nostril as if——”

“What’s that? What’s that?” Cleek’s voice flicked in like the crack of a whip. “Good God! Dancing round in circles? His mouth open? His tongue hanging out? His fingers thrust into his nostrils? Was that what you said?”

“Yes. Why? Do you see anything promising in that fact, Cleek? It seems to excite you.”

“Never mind about that. Stick to the subject. Was that report found to be correct, then?”

“In a measure, yes. Only, of course, one had to take the tramp’s assertion that the man had been calling out ‘Sapphires’ upon faith, for when discovered and conveyed to the hospital, he was in a comatose condition and beyond making any sound at all. He died, without recovering consciousness, about twenty minutes after Petrie’s arrival; and, although the doctors performed a post-mortem immediately after the breath had left his body, there was not a trace of anything to be found that differed in the slightest from the other cases. Heart, brain, liver, lungs—all were in a healthy condition, and beyond the reddened throat and the signs of recent enteric there was nothing abnormal.”

“But his lips—his lips, Mr. Narkom? Was there a smear of earth upon them? Was he lying on his face when found? Were his fingers clenched in the grass? Did it look as if he had been biting the soil?”
