What is General Zaroff’s implication at the end of this section of the text?

The smile on the general's face widened. "To date I have not lost," he said. Then he added, hastily: "I don't wish you to think me a braggart, Mr. Rainsford. Many of them afford only the most elementary sort of problem. Occasionally I strike a tartar. One almost did win. I eventually had to use the dogs."

"The dogs?"

"This way, please. I'll show you."

The general steered Rainsford to a window. The lights from the windows sent a flickering illumination that made grotesque patterns on the courtyard below, and Rainsford could see moving about there a dozen or so huge black shapes; as they turned toward him, their eyes glittered greenly.

"A rather good lot, I think," observed the general. "They are let out at seven every night. If anyone should try to get into my house--or out of it--something extremely regrettable would occur to him." He hummed a snatch of song from the Folies Bergere.

"And now," said the general, "I want to show you my new collection of heads. Will you come with me to the library?"

"I hope," said Rainsford, "that you will excuse me tonight, General Zaroff. I'm really not feeling well."

"Ah, indeed?" the general inquired solicitously. "Well, I suppose that's only natural, after your long swim. You need a good, restful night's sleep. Tomorrow you'll feel like a new man, I'll wager. Then we'll hunt, eh?
I've one rather promising prospect--" Rainsford was hurrying from the room.

"Sorry you can't go with me tonight," called the general. "I expect rather fair sport--a big, strong, black. He looks resourceful--Well, good night, Mr. Rainsford; I hope you have a good night's rest."

The bed was good, and the pajamas of the softest silk, and he was tired in every fiber of his being, but nevertheless Rainsford could not quiet his brain with the opiate of sleep. He lay, eyes wide open. Once he thought he heard stealthy steps in the corridor outside his room. He sought to throw open the door; it would not open. He went to the window and looked out. His room was high up in one of the towers. The lights of the chateau were out now, and it was dark and silent; but there was a fragment of sallow moon, and by its wan light he could see, dimly, the courtyard. There, weaving in and out in the pattern of shadow, were black, noiseless forms; the hounds heard him at the window and looked up, expectantly, with their green eyes. Rainsford went back to the bed and lay down. By many methods he tried to put himself to sleep. He had achieved a doze when, just as morning began to come, he heard, far off in the jungle, the faint report of a pistol.

General Zaroff did not appear until luncheon. He was dressed faultlessly in the tweeds of a country squire. He was solicitous about the state of Rainsford's health.

"As for me," sighed the general, "I do not feel so well. I am worried, Mr. Rainsford. Last night I detected traces of my old complaint."

To Rainsford's questioning glance the general said, "Ennui. Boredom."

Then, taking a second helping of crêpes Suzette, the general explained: "The hunting was not good last night. The fellow lost his head. He made a straight trail that offered no problems at all. That's the trouble with these sailors; they have dull brains to begin with, and they do not know how to get about in the woods. They do excessively stupid and obvious things. It's most annoying. Will you have another glass of Chablis, Mr. Rainsford?"

"General," said Rainsford firmly, "I wish to leave this island at once."

The general raised his thickets of eyebrows; he seemed hurt. "But, my dear fellow," the general protested, "you've only just come. You've had no hunting--"

"I wish to go today," said Rainsford. He saw the dead black eyes of the general on him, studying him. General Zaroff's face suddenly brightened.

He filled Rainsford's glass with venerable Chablis from a dusty bottle.

"Tonight," said the general, "we will hunt--you and I."

Rainsford shook his head. "No, general," he said. "I will not hunt."

The general shrugged his shoulders and delicately ate a hothouse grape. "As you wish, my friend," he said. "The choice rests entirely with you. But may I not venture to suggest that you will find my idea of sport more diverting than Ivan's?"

He nodded toward the corner to where the giant stood, scowling, his thick arms crossed on his hogshead of chest.

"You don't mean--" cried Rainsford.

"My dear fellow," said the general, "have I not told you I always mean what I say about hunting? This is really an inspiration. I drink to a foeman worthy of my steel--at last." The general raised his glass, but Rainsford sat staring at him.

"You'll find this game worth playing," the general said enthusiastically." Your brain against mine. Your woodcraft against mine. Your strength and stamina against mine. Outdoor chess! And the stake is not without value, eh?"

"And if I win--" began Rainsford huskily.

"I'll cheerfully acknowledge myself defeat if I do not find you by midnight of the third day," said General Zaroff. "My sloop will place you on the mainland near a town." The general read what Rainsford was thinking.

"Oh, you can trust me," said the Cossack. "I will give you my word as a gentleman and a sportsman. Of course you, in turn, must agree to say nothing of your visit here."

"I'll agree to nothing of the kind," said Rainsford.

"Oh," said the general, "in that case--But why discuss that now? Three days hence we can discuss it over a bottle of Veuve Cliquot, unless--"

The general sipped his wine.

Then a businesslike air animated him. "Ivan," he said to Rainsford, "will supply you with hunting clothes, food, a knife. I suggest you wear moccasins; they leave a poorer trail. I suggest, too, that you avoid the big swamp in the southeast corner of the island. We call it Death Swamp. There's quicksand there. One foolish fellow tried it. The deplorable part of it was that Lazarus followed him. You can imagine my feelings, Mr. Rainsford. I loved Lazarus; he was the finest hound in my pack. Well, I must beg you to excuse me now. I always' take a siesta after lunch. You'll hardly have time for a nap, I fear. You'll want to start, no doubt. I shall not follow till dusk. Hunting at night is so much more exciting than by day, don't you think? Au revoir, Mr. Rainsford, au revoir." General Zaroff, with a deep, courtly bow, strolled from the room.

From another door came Ivan. Under one arm he carried khaki hunting clothes, a haversack of food, a leather sheath containing a long-bladed hunting knife; his right hand rested on a cocked revolver thrust in the crimson sash about his waist.

Rainsford had fought his way through the bush for two hours. "I must keep my nerve. I must keep my nerve," he said through tight teeth.

He had not been entirely clearheaded when the chateau gates snapped shut behind him. His whole idea at first was to put distance between himself and General Zaroff; and, to this end, he had plunged along, spurred on by the sharp rowers of something very like panic. Now he had got a grip on himself, had stopped, and was taking stock of himself and the situation. He saw that straight flight was futile; inevitably it would bring him face to face with the sea. He was in a picture with a frame of water, and his operations, clearly, must take place within that frame.

"I'll give him a trail to follow," muttered Rainsford, and he struck off from the rude path he had been following into the trackless wilderness. He executed a series of intricate loops; he doubled on his trail again
and again, recalling all the lore of the fox hunt, and all the dodges of the fox. Night found him leg-weary, with hands and face lashed by the branches, on a thickly wooded ridge. He knew it would be insane to blunder on through the dark, even if he had the strength. His need for rest was imperative and he thought, "I have played the fox, now I must play the cat of the fable." A big tree with a thick trunk and outspread branches was near by, and, taking care to leave not the slightest mark, he climbed up into the crotch, and, stretching out on one of the broad limbs, after a fashion, rested. Rest brought him new confidence and almost a feeling of security. Even so zealous a hunter as General Zaroff could not trace him there, he told himself; only the devil himself could follow that complicated trail through the jungle after dark. But perhaps the general was a devil--

An apprehensive night crawled slowly by like a wounded snake and sleep did not visit Rainsford, although the silence of a dead world was on the jungle. Toward morning when a dingy gray was varnishing the sky, the cry of some startled bird focused Rainsford's attention in that direction. Something was coming through the bush, coming slowly, carefully, coming by the same winding way Rainsford had come. He flattened himself down on the limb and, through a screen of leaves almost as thick as tapestry, he watched. . . . That which was approaching was a man.

It was General Zaroff. He made his way along with his eyes fixed in utmost concentration on the ground before him. He paused, almost beneath the tree, dropped to his knees and studied the ground. Rainsford's impulse was to hurl himself down like a panther, but he saw that the general's right hand held something metallic--a small automatic pistol.

The hunter shook his head several times, as if he were puzzled. Then he straightened up and took from his case one of his black cigarettes; its pungent incenselike smoke floated up to Rainsford's nostrils.

Rainsford held his breath. The general's eyes had left the ground and were traveling inch by inch up the tree. Rainsford froze there, every muscle tensed for a spring. But the sharp eyes of the hunter stopped before they reached the limb where Rainsford lay; a smile spread over his brown face. Very deliberately he blew a smoke ring into the air; then he turned his back on the tree and walked carelessly away, back along the trail he had come. The swish of the underbrush against his hunting boots grew fainter and fainter.

The pent-up air burst hotly from Rainsford's lungs. His first thought made him feel sick and numb. The general could follow a trail through the woods at night; he could follow an extremely difficult trail; he must have uncanny powers; only by the merest chance had the Cossack failed to see his quarry.

Rainsford's second thought was even more terrible. It sent a shudder of cold horror through his whole being. Why had the general smiled? Why had he turned back?

Rainsford did not want to believe what his reason told him was true, but the truth was as evident as the sun that had by now pushed through the morning mists. The general was playing with him! The general was saving him for another day's sport! The Cossack was the cat; he was the mouse. Then it was that Rainsford knew the full meaning of terror.
