Don Luis unfolded the page of the note-book on which Vorski had written down the prophecy and, holding it under his eyes, continued:
"What remains to be said is not so important, once the general explanation is accepted. Nevertheless, we must go into detail to some slight extent, show the mechanism of the affair imagined and built up by Vorski and lastly come to the part played by our attractive ancient Druid . . . . So we are now in the month of June. This is the season fixed for the execution of the thirty victims. It was evidently appointed by Brother Thomas because the rhythm of his verse called for a month in one syllable, just as the year fourteen and three was selected because three rhymes with be and tree and just as Brother Thomas decided upon the number of thirty victims because thirty is the number of the Sarek reefs and coffins. But Vorski takes it as a definite command. Thirty victims are needed in June '17. They will be provided. They will be provided on condition that the twenty-nine inhabitants of Sarek—we shall see presently that Vorski has his thirtieth victim handy—consent to stay on the island and await their destruction. Well, Vorski suddenly hears of the departure of Honorine and Maguennoc. Honorine will come back in time. But how about Maguennoc? Vorski does not hesitate: he sends Elfride and Conrad on his tracks, with instructions to kill him and to wait. He hesitates the less because he believes, from certain words which he has overheard, that Maguennoc has taken with him the precious stone, the miraculous gem which must not be touched but which must be left in its leaden sheath (this is the actual phrase used by Maguennoc)!
"Elfride and Conrad therefore set out. One morning, at an inn, Elfride mixes poison with the coffee which Maguennoc is drinking (the prophecy has stated that there will be poison). Maguennoc continues his journey. But in an hour or two he is seized with intolerable pain and dies, almost immediately, on the bank by the road-side. Elfride and Conrad come up and go through his pockets. They find nothing, no gem, no precious stone. Vorski's hopes have not been realized. All the same, the corpse is there. What are they to do with it? For the time being, they fling it into a half-demolished hut, which Vorski and his accomplices had visited some months before. Here Véronique d'Hergemont discovers the body . . . and an hour later fails to find it there. Elfride and Conrad, keeping watch close at hand, have taken it away and hidden it, still for the time being, in the cellars of a little empty country-house.
"There's one victim accounted for. We may observe, in passing, that Maguennoc's predictions relating to the order in which the thirty victims are to be executed—beginning with himself—have no basis. The prophecy doesn't mention such a thing. In any case, Vorski goes to work at random. At Sarek he carries off François and Stéphane Maroux and then, both as a measure of precaution and in order to cross the island without attracting attention and to enter the Priory more easily, he dresses himself in Stéphane's clothes, while Raynold puts on François'. The job before them is an easy one. The only people in the house are an old man, M. d'Hergemont, and a woman, Marie Le Goff. As soon as these are got rid of, the rooms and Maguennoc's in particular will be searched. Vorski, as yet unaware of the result of Elfride's expedition, would not be surprised if Maguennoc had left the miraculous jewel at the Priory.
"The first to fall is the cook, Marie Le Goff, whom Vorski takes by the throat and stabs with a knife. But it so happens that the ruffian's face gets covered with blood; and, seized with one of those fits of cowardice to which he is subject, he runs away, after loosing Raynold upon M. d'Hergemont.
"The fight between the boy and the old man is a long one. It is continued through the house and, by a tragic chance, ends before Véronique d'Hergemont's eyes. M. d'Hergemont is killed. Honorine arrives at the same moment. She drops, making the fourth victim.
"Matters now begin to go quickly. Panic sets in during the night. The people of Sarek, frightened out of their wits, seeing that Maguennoc's predictions are being fulfilled and that the hour of the disaster which has so long threatened their island is about to strike, make up their minds to go. This is what Vorski and his son are waiting for. Taking up their position in the motor-boat which they have stolen, they rush after the runaways and the abominable hunt begins, the great disaster foretold by Brother Thomas:
"'There will be shipwrecks, terrors, grief and crimes.'
"Honorine, who witnesses the scene and whose brain is already greatly upset, goes mad and throws herself from the cliff.
"Thereupon we have a lull of a few days, during which Véronique d'Hergemont explores the Priory and the island without being disturbed. As a matter of fact, after their successful hunt, leaving only Otto, who spends his time drinking in the cells, the father and son have gone off in the boat to fetch Elfride and Conrad and to bring back Maguennoc's body and fling it in the water within sight of Sarek, since Maguennoc of necessity has one of the thirty coffins earmarked for his reception.
