"Oh, but of course!" Blood's irony laughed in his eyes. "Yet, whatever you may be, I warn you that unless you yield to a demand that I consider just and therefore uphold, you may look for trouble, and it would not surprise me if you never leave Cartagena at all, nor convey a single gold piece home to France."

"Ah, pardieu! Am I to understand that you are threatening me?"

"Come, come, M. le Baron! I warn you of the trouble that a little prudence may avert. You do not know on what a volcano you are sitting. You do not know the ways of buccaneers. If you persist, Cartagena will be drenched in blood, and whatever the outcome the King of France will not have been well served."

That shifted the basis of the argument to less hostile ground. Awhile yet it continued, to be concluded at last by an ungracious undertaking from M. de Rivarol to submit to the demands of the buccaneers. He gave it with an extreme ill-grace, and only because Blood made him realize at last that to withhold it longer would be dangerous. In an engagement, he might conceivably defeat Blood's followers. But conceivably he might not. And even if he succeeded, the effort would be so costly to him in men that he might not thereafter find himself in sufficient strength to maintain his hold of what he had seized.

The end of it all was that he gave a promise at once to make the necessary preparations, and if Captain Blood and his officers would wait upon him on board the Victorieuse to-morrow morning, the treasure should be produced, weighed in their presence, and their fifth share surrendered there and then into their own keeping.

Among the buccaneers that night there was hilarity over the sudden abatement of M. de Rivarol's monstrous pride. But when the next dawn broke over Cartagena, they had the explanation of it. The only ships to be seen in the harbour were the Arabella and the Elizabeth riding at anchor, and the Atropos and the Lachesis careened on the beach for repair of the damage sustained in the bombardment. The French ships were gone. They had been quietly and secretly warped out of the harbour under cover of night, and three sails, faint and small, on the horizon to westward was all that remained to be seen of them. The absconding M. de Rivarol had gone off with the treasure, taking with him the troops and mariners he had brought from France. He had left behind him at Cartagena not only the empty-handed buccaneers, whom he had swindled, but also M. de Cussy and the volunteers and negroes from Hispaniola, whom he had swindled no less.

The two parties were fused into one by their common fury, and before the exhibition of it the inhabitants of that ill-fated town were stricken with deeper terror than they had yet known since the coming of this expedition.

Captain Blood alone kept his head, setting a curb upon his deep chagrin. He had promised himself that before parting from M. de Rivarol he would present a reckoning for all the petty affronts and insults to which that unspeakable fellow — now proved a scoundrel — had subjected him.

"We must follow," he declared. "Follow and punish."

At first that was the general cry. Then came the consideration that only two of the buccaneer ships were seaworthy — and these could not accommodate the whole force, particularly being at the moment indifferently victualled for a long voyage. The crews of the Lachesis and Atropos and with them their captains, Wolverstone and Yberville, renounced the intention. After all, there would be a deal of treasure still hidden in Cartagena. They would remain behind to extort it whilst fitting their ships for sea. Let Blood and Hagthorpe and those who sailed with them do as they pleased.

Then only did Blood realize the rashness of his proposal, and in attempting to draw back he almost precipitated a battle between the two parties into which that same proposal had now divided the buccaneers. And meanwhile those French sails on the horizon were growing less and less. Blood was reduced to despair. If he went off now, Heaven knew what would happen to the town, the temper of those whom he was leaving being what it was. Yet if he remained, it would simply mean that his own and Hagthorpe's crews would join in the saturnalia and increase the hideousness of events now inevitable. Unable to reach a decision, his own men and Hagthorpe's took the matter off his hands, eager to give chase to Rivarol. Not only was a dastardly cheat to be punished but an enormous treasure to be won by treating as an enemy this French commander who, himself, had so villainously broken the alliance.

When Blood, torn as he was between conflicting considerations, still hesitated, they bore him almost by main force aboard the Arabella.

Within an hour, the water-casks at least replenished and stowed aboard, the Arabella and the Elizabeth put to sea upon that angry chase.

"When we were well at sea, and the Arabella's course was laid," writes Pitt, in his log, "I went to seek the Captain, knowing him to be in great trouble of mind over these events. I found him sitting alone in his cabin, his head in his hands, torment in the eyes that stared straight before him, seeing nothing."

"What now, Peter?" cried the young Somerset mariner. "Lord, man, what is there here to fret you? Surely 't isn't the thought of Rivarol!"

"No," said Blood thickly. And for once he was communicative. It may well be that he must vent the thing that oppressed him or be driven mad by it. And Pitt, after all, was his friend and loved him, and, so, a proper man for confidences. "But if she knew! If she knew! O God! I had thought to have done with piracy; thought to have done with it for ever. Yet here have I been committed by this scoundrel to the worst piracy that ever I was guilty of. Think of Cartagena! Think of the hell those devils will be making of it now! And I must have that on my soul!"

"Nay, Peter— 't isn't on your soul; but on Rivarol's. It is that dirty thief who has brought all this about. What could you have done to prevent it?"

"I would have stayed if it could have availed."

"It could not, and you know it. So why repine?"

"There is more than that to it," groaned Blood. "What now? What remains? Loyal service with the English was made impossible for me. Loyal service with France has led to this; and that is equally impossible hereafter. What to live clean, I believe the only thing is to go and offer my sword to the King of Spain."

But something remained — the last thing that he could have expected — something towards which they were rapidly sailing over the tropical, sunlit sea. All this against which he now inveighed so bitterly was but a necessary stage in the shaping of his odd destiny.

Setting a course for Hispaniola, since they judged that thither must Rivarol go to refit before attempting to cross to France, the Arabella and the Elizabeth ploughed briskly northward with a moderately favourable wind for two days and nights without ever catching a glimpse of their quarry. The third dawn brought with it a haze which circumscribed their range of vision to something between two and three miles, and deepened their growing vexation and their apprehension that M. de Rivarol might escape them altogether.

Their position then — according to Pitt's log — was approximately 75 deg. 30' W. Long. by 17 deg. 45' N. Lat., so that they had Jamaica on their larboard beam some thirty miles to westward, and, indeed, away to the northwest, faintly visible as a bank of clouds, appeared the great ridge of the Blue Mountains whose peaks were thrust into the clear upper air above the low-lying haze. The wind, to which they were sailing very close, was westerly, and it bore to their ears a booming sound which in less experienced ears might have passed for the breaking of surf upon a lee shore.
