"Carried off," replied the man. "Carried off . . . and his lordship as well."

"Ah!" cried Simon, overwhelmed.

The man continued:

"Rolleston is their leader, Wilfred Rolleston. He came up to me this morning at sunrise, as I was seeing to the horses, and asked me if Lord Bakefield was still there. Then, without waiting for an answer, he knocked me flat, with the help of his men, and had me carried here, where they laid an ambush for his lordship. They didn't mind what they said before me; and I learnt that Mr. Williams, the secretary, and Charles, my fellow-servant, who were to have joined us and increased the escort, had been attacked by them and, most likely, killed. I learnt too that Rolleston's idea was to keep Miss Bakefield as a hostage and to send his lordship to his Paris banker's to get the ransom. Later on, they left me alone. Then I heard two shots and, a little after, they returned with his lordship and Miss Bakefield. Both of them had their hands and feet tied."

"At what time did all this happen?" asked Simon, quivering with impatience.

"Nine o'clock, sir, or thereabouts."

"Then they have a day's start of us?"

"Oh, no! There were provisions in the saddle-bags. They sat eating and drinking and then went to sleep. It was at least two o'clock in the afternoon when they strapped his lordship and Miss Bakefield to a couple of horses and started."

"In what direction?"

"That way," said the man-servant, pointing.

"Antonio," cried Simon, "we must catch them before night! The ruffian's escort is on foot. Three hours' gallop will be enough.

"Our horses are badly done up," objected the Indian.

"They've got to get there, if it kills them."

Simon Dubosc gave the servant his instructions:

"Get Mr. Rolleston under shelter in the wreck, look after him and don't leave him for a second. Jim, can I count on you?"

"Yes."

"And on your father?"

"All depends."

"Fifty pounds for him if the wounded man is in Brighton, safe and sound, in two days' time."

"Make it a hundred," said Jim. "Not a penny less."

"Very well, a hundred."

At six o'clock in the evening, Simon and Antonio returned to the Indians' camp. They quickly bridled and saddled their horses, while Old Sandstone, who was strolling around, ran up to them shouting:

"My fault, Simon! I swear we are over my fault, the fault in the Paris basin, which I traced to Maromme and near the Ridin de Dieppe . . .

the one whose fracture caused the whole upheaval. Get on your horse, so that I may give you my proofs. There's a regular Eocene and Pliocene mixture over there which is really typical. . . . Heavens, man, listen to me, can't you?"

Simon stepped up to him and, with drawn features, shouted:

"This is no time to listen to your nonsense!"

"What do you mean?" stammered the old fellow, utterly bewildered.

"Mean? Why, shut up!"

And the young man leapt into the saddle:

"Are you coming, Antonio?"

"Yes. My mates will follow our trail. I shall leave a mark from spot to spot; and I hope we shall all be united again to-morrow."

As they were starting, Dolores, on horseback, brought up her mount alongside theirs.

"No!" said Antonio. "You come on with the others. The professor can't walk all the time."

She made no reply.

"I insist on your keeping with the others," repeated the half-breed, more severely.

But she set her horse at a trot and caught up with Simon.

For more than an hour they followed a direction which Simon took to be south by south-east, that is to say, the direction of France. The half-breed thought the same:

"The main thing," he said, "is to get near the coast, as our beasts have only enough food to last them till to-morrow evening. The water question also might become troublesome."

"I don't care what happens to-morrow," Simon rejoined.

They made much slower progress than they had hoped to do. Their mounts were poor, spiritless stuff. Moreover, they had to stop at intervals to decipher the tracks which crossed one another in the wet sand or to pick them up on rocky ground. Simon became incensed at each of these halts.

All around them the scene was like that which they had observed early in the afternoon; the land rose and fell in scarcely perceptible undulations; it was a dismal, monotonous world, with its graveyards of ships and skeleton steamers. Prowling figures crossed it in all directions. Antonio shouted questions to them as he pa.s.sed. One of them said that he had met two hors.e.m.e.n and four pedestrians leading a couple of horses on which were bound a man and a woman whose fair hair swept the ground.

"How long ago was this?" asked Simon, in a hoa.r.s.e voice.

"Forty minutes, or fifty at the most."

He dug his heels into his horse's flanks and set off at a gallop, stooping over the animal's neck in order not to lose the scoundrel's track. Antonio found it difficult to follow him, while Dolores erect in her saddle, with a serious face and eyes fixed on the distant horizon, kept up with him without an effort.

Meanwhile the light was failing, and the riders felt as though the darkness were about to swoop down on them from the heavy clouds in which it was gathering.

"We shall get there . . . we must," repeated Simon. "I feel certain we shall see them in ten minutes. . . ."

He told Dolores in a few words what he had heard of Isabel's abduction. The thought that she was in pain caused unendurable torture. His overwrought mind pictured her a captive among savages torturing her for their amus.e.m.e.nt, while her blood-bedabbled head was gashed by the stones along the track. He followed in imagination all the stages of her last agony; and he had such a keen impression of speed contending with death, he searched the horizon with so eager a gaze, that he scarcely heeded a strident call from the half-breed, a hundred yards in the rear.

Dolores turned and calmly observed:

"Antonio's horse has fallen."

"Antonio can follow us," said Simon.
