The maniacal Rawdon was the worst difficulty, and I honestly believe that only the Chief's restraining presence saved me from the necessity of winging him with a revolver bullet to prevent his setting fire to the bungalow. That "bloody wombat" had dodged him once from that shack and he wasn't going to take chances on its happening again. The Chief and I finally induced him to leave his "ring of death" intact round the bungalow and come in and search for himself. That gave me a chance for a quiet word with Harpool, whom I did not want to have push on to town for fear he would start a search that might extend to the Mambare. Indeed, he admitted he was afraid that his man might have doubled back to Townsville and got off to the Singapore boat, which had doubtless sailed at midnight. He had lost a badly-wanted counterfeiter a fortnight ago that way. The skippers never seemed very keen to co-operate in a search of their ships. Too many little smuggling games of their own probably.

I suggested to Harpool that he have a bath, a change of clothes—my togs were about his size—and a snack of early breakfast. Afterwards—since his horse was gone—I would drive him down in my trap. In the meantime he could ring up the Police Station and give any orders he thought desirable by 'phone. (This latter suggestion I made in full knowledge of the fact that the line must be down for over a mile. I had seen myself where uprooted trees were responsible for wide hiatuses.) If it was in any way possible without arousing his suspicions, it was my intention to detain Harpool until I was sure the Mambare had sailed.

The Chief fell in with my suggestion readily, and felt so much bucked up after a bath and a couple of whiskies-and-soda that he did not appear seriously upset when the telephone turned an irresponsive ear to him. Like the straightforward gentleman he was, he accepted at once my assurance that Ranga had not entered the house again, and took no hand in Rawdon's wild scrimmages, which carried him from cellar to garret with no other result than the brushing of a bit more of the bloom off "Honeymoon Bungalow" with the soles of his hobnailed boots. Madder than ever after his vain search, he surlily refused my invitation to remain for a cup of the coffee that his Chink friend of the night before was already preparing in the kitchen, and slogged off down the road, followed by three draggled hounds and two cursing helpers. I was a good deal cheered by the thought that it was unlikely that any of them would be getting through to town, without swimming, for another twelve hours at least.

Before he left Rawdon turned over to the Chief the little piece of red rag he had been using to put the dogs on the scent with. It was at this time that Harpool told me of "Squid" Saunders' suggestion, and of the visit to the schooner in search of a clue. I did not tell him that I recognized the rag as one which Ranga had used to wrap his little Malay flute in, and that it had undoubtedly been left there the morning the big fellow helped carry Hartley Allen to the quarantine launch. It was interesting, however, to know that Ranga was absolutely guiltless of the outrage to which he had confessed. I thought I could just conceive how a well-guarded passion for the girl might have prompted that chivalrous attempt to shield her from suspicion; but why had Rona herself committed the ghastly crime?—and how? It was many months before I was to have an answer to those questions, and they came from the lips of the last person from whom I could have expected them.

Direct and straightforward as ever, Harpool was visibly impressed by my suggestion that Ranga had probably remained hidden near the fall until the pursuit had passed, and after returning to the bungalow and finding it dark, had retraced his steps and adopted the desperate expedient of trying to escape the dogs by riding down the flume. That reminded him that they had found the gate of the intake closed when they first reached it, and that it had occurred to him at the time that the fugitive might have done this so that he could walk down the bottom of the flume without risk of being carried away by the water. This would account for the patch of scent the hounds found at that point. The Chief said that he was for pushing along the path by the flume, but that Rawdon scouted his theory, insisting that their man had jumped back into the water and gone on wading downstream. The hound-master had carried his point, but, to be on the safe side, they had ratcheted up the gate to its full aperture and turned a stream down the flume heavy enough, he was afraid, almost to carry the sugar mill into the sea. And that reminded me (though, obviously, I could not speak of it) that I had not heard the roar of the mill's machinery when I paused at the brow of the cliff. There was no doubt it was hung up for some reason. Was it possible that Ranga had made his escape after coasting right down into the crushing gear? But of course not. He would never have been able to get away unpursued, even if he had survived.

I welcomed for two reasons Harpool's suggestion that we ride down the flume and investigate as soon as breakfast was over. It would keep him away from town until the Mambare had sailed for one thing, and, for another, it would give me a chance to fathom the mystery that lay at the end of that trail of blood leading down into the rift in the cliff. It seemed probable to me that both Rona and Ranga, after the former had overtaken him—probably at the foot of the fall—had started down the flume on foot. Whether there would be any indications of what had befallen when the water overtook them remained to be seen.

The gate was still wide open when we rode along beside the intake, but halfway down to the coast we met a man from the mill who said that he was going up to shut the flow off so that a break near the lower end could be repaired. The wires were down from the storm, he said, making it impossible to 'phone directions to the plantation office. The break was a bit of a mystery, he added. Flume opened right out. There were indications that some large animal—perhaps a bullock—had been carried down—probably washed in at the upper end while the stream was at flood. Funny part of it was, though, that there was no trace to be found of the bullock below the break. Must have been washed right on into the sea.

Harpool pushed on eagerly after hearing that significant piece of news, and we reached the head of the first steep pitch at the top of the cliff some minutes before the water had ceased to flow. As I did not care to have the Chief discover the trail of blood leading down to the sea for a while yet, I proposed that we tie our horses here and walk down the top of the flume on a narrow board that evidently had been placed there for the use of workmen when repairs were necessary. It proved ticklish going—both on account of the incline and the elevation,—but nothing to trouble seriously a man with a sure foot and a steady head. Harpool, who was up first, led the way, I following closely.

If the power of the flying bolt of water in the bottom of the flume had been impressive on the occasion of my first visit, it was a vast deal more so now, both on account of the greatly increased volume of flow and because of my certain knowledge that a human being—perhaps two of them—had gone down that chute, where I had been assured that a team of bullocks could not hold a man—and survived.

The foot-wide board on which we were walking was nailed to the left side of the flume. The top of the right side was a rough line of unplaned two-inch pine planks. Harpool had only taken a step or two when he brought up short with an exclamation of surprise and horror. "Look at that top board on the other side!" he shouted; "raw, red meat all the way from here right out of sight round the bend at the bottom!"
