For exactly a month Julien disappeared. At the end of that time, looking very brown, a shade thinner, and possessed of a knowledge of the older towns of Normandy which would not have disgraced a guidebook, he arrived one cold, gray morning at the Gare du Nord. During all this time he had scarcely seen one familiar face. It was an unpleasant shock for him, as he waited for his baggage in the Customs House, to realize that he was being watched from behind a pile of trunks by the little man who had shown so much interest in him at the CafÉ l'AthÉnÉe on the night he had left England. The sight somehow annoyed him. He crossed the room and accosted his late subordinate.

"What is your name?" he asked coldly. "You are in the Intelligence
Department, I believe?"

"My name is Foster, Sir Julien," the young man replied, after a moment's hesitation.

"What are you doing over here?"

The young man hesitated.

"You will excuse me, Sir Julien," he said slowly, "but I am responsible only to the permanent officials in control of my office. Besides,—"

"You can tell me at least how long you have been in Paris?" Julien interrupted.

"Since the night, Sir Julien, when you came as far as Boulogne."

"May I ask," Julien demanded, "whether I am going to be subject to your espionage?"

The young man whose name was Foster looked blandly at a pile of luggage which was just arriving.

"I am not at liberty, Sir Julien," he said, "to explain my instructions."

Julien shrugged his shoulders.

"Do as you like, of course. At the same time, let me tell you that you irritate me. Keep out of my sight as much as possible. It will be better for you."

Julien turned and left him there, declared his luggage, and was driven to a quiet hotel in the Rue de Rivoli. There he had a bath, changed his clothes, and strolled up the Champs ÉlysÉes towards the Bois. The sun had come out and the avenue was crowded with automobiles and carriages. He walked steadily on until he reached the first of the cafÉs in the Bois. He took a chair and watched the crowd. A peculiar sensation of loneliness oppressed him, a loneliness of which he had been scarcely conscious during this last month's wanderings among the quiet places. Paris had seemed so different to him on his last visit. He was surrounded by friends and people who were anxious to become his friends. He was in charge of a difficult mission which he was conscious of conducting with skill. Everywhere he was meeting English people of his own order, all delighted to see him, all pleased with his notice. His few days in Paris were merely a change in the kaleidoscope from London. The life—everything else—was the same. This time he was like a man cast upon a desert island. He sat at his little table, sipping a glass of vermouth, and conscious that no man in Paris had fewer friends. The clubs were closed to him, there were no official visits to pay, no calls to make, no familiar faces to look for. He was a man who had had his day, a man disgraced, a man in whom the people had lost faith, who was dead politically and socially. He thought his position over carefully from every point of view. It was ruin, utter and complete. He had disclosed a valuable political secret to a woman who had not hesitated to make use of it. Nothing could be more ignoble. He tried to fancy for himself some new life under altered conditions, but everywhere he seemed to run up against some possibility, some combination of circumstances which included a share in things which were absolutely finished. His brain refused to fashion for him the thought of any life which could leave outside everything which had been of account to him up till now. Even in London, among the working classes, it might have been easier. He remembered those few vivid speeches of Kendricks'. What a gift the man had! Always he seemed to see big things in life smouldering underneath the lives of these ordinary people—big things unsuspected, invisible. There was nothing of the sort to be found here. The only Paris Julien had ever known was closed to him. Paris the vicious repelled him instinctively. He was here, he had even looked forward to coming, but now that he had arrived there was nothing for him to do. After all, he had better have found some far distant corner in Switzerland or Italy. There was no club for him to go to, no interest in perusing the newspapers, no visits from ambassadors to think about. The puzzles of his daily life were ended. There was nothing for him to do where he was but to eat and to drink and to sleep!

He lunched at a restaurant of which he had never heard before, and there, to his anger, almost at the next table, he found Foster. With a trace of his former imperiousness of manner, he summoned him. The young man rose, after a moment's hesitation, and obeyed the mandate.

"What are you doing here?" Julien demanded.

"Lunching, sir," the young man replied. "The place has been recommended to me. I do not know Paris well."

"You lie," Julien declared. "Unless you knew Paris well, you wouldn't be here for Number 3 Branch. Tell me, are you still watching me?"

"That is a question, Sir Julien, which, as I said before, I am not at liberty to answer."

Julien drew a little breath between his teeth.

"Look here," he continued, "I want to warn you that I am a bad-tempered man. You can write home if you like and tell them that you met me coming out of the German Embassy and the Russian Embassy and the Italian Embassy, with a list of prices in my hands for different pieces of information. Is that what you're afraid of, eh?"

"Sir Julien," the young man answered, "I have to make reports only. It is not my business to question the necessity for them."

Julien laughed. After all, the little man was right.

"Well, perhaps I do need looking after. Is there any particular place where you would like me to dine? I don't want to bring you out into the byways if I can help it."

The young man excused himself politely. Julien finished his luncheon and then took a carriage back to his hotel. He found half-a-dozen visiting cards in his box and glanced at them eagerly. Every one of them was from the representative of a newspaper. He tore them into pieces, left a curt message for their bearers, and went up to his room. A telegram was lying upon his bureau. He tore it open and read:

Call on Madame Christophor this afternoon.

He frowned and threw the unsigned telegram into a wastepaper-basket.

"That decides it," he muttered to himself. "I will not call upon Madame
Christophor."

Nevertheless, he changed into calling attire and presently strolled out once more into the sunshine. From habit he turned into the Champs ÉlysÉes. The sight of a group of acquaintances drove him into a side street. He walked for a short distance and then paused to see his whereabouts. He was in the Avenue de St. Paul. He studied the numbers. Exactly opposite was Number 17. He stood there, gazing at the house, and at that moment a large automobile glided up to the front door. The footman sprang down and a lady descended, passing within a few feet of him. She was tall, very elegant, and her eyes, gaining, perhaps, a little color from the pallor of her cheeks, were the most beautiful shade of violet-blue which he had ever seen. She was a woman whom it was impossible not to notice. Julien stood quite still, watching her. The footman who had stepped down in advance had rung the bell, and the postern door already stood open. The lady did not at once enter. She was looking at Julien. This, then, was Madame Christophor! He was aware at that moment of two distinct impressions—one was that she knew perfectly well who he was; the other that at any cost, however gauche it might seem, it was better for him to ignore the faint gleam of recognition which already lent the dawn of a gracious smile to her lips.

The woman was certainly expecting him to speak. Every second her hesitation seemed more purposeful. Julien, however, with an effort which was almost savage, set his teeth and walked on. She looked after him for a moment and began to laugh softly to herself. Julien walked steadily on till he had reached the corner of the street. Then he turned away abruptly and without glancing around. He was angry with himself, angry at the sound of that faint, musical laugh. He had quite made up his mind not to call upon Madame Christophor. It would, in fact, now be impossible. He would never be able to explain his avoidance of her.

He was in a part of Paris of which he knew nothing, but he walked on aimlessly, anxious only to escape the vicinity of the clubs and of the fashionable thoroughfares. Suddenly he was conscious that an automobile had drawn up close to the curbstone by his side. The footman sprang lightly down and accosted him.

"Monsieur," he announced, "Madame Christophor has sent her automobile.
She would be happy to receive you at once."

Julien glanced inside the automobile. It was daintily upholstered in white. A pile of cushions lay on the seat, there was a glove upon the floor, the faint fragrance of roses seemed to steal out. Almost he fancied that the woman's face was there, leaning a little towards him, with the curious smile about the lips, the wonderful eyes glowing into his. Then he set his teeth.

"You had better inform your mistress," he said, "that there is some mistake. I have not the honor of the acquaintance of Madame Christophor. You have followed the wrong person."

The man hesitated. He seemed perplexed.

"But, monsieur," he persisted, "madame pointed you out herself. It was only because of a block in the roadway that we were not able to catch you up before. We have, indeed, never lost sight of you."

Julien shook his head. "Pray assure madame," he said, "of my most respectful regrets. I have not the honor of her acquaintance."

He walked on. The two men sat for a moment on the box of the car, watching him. Then they turned around and the car disappeared. Julien jumped into a little carriage and drove back to his hotel. As he passed through into the office, the clerk leaned forward.

"Monsieur is desired upon the telephone," he announced.

Julien frowned.

"Who is it?"

The man shrugged his shoulders and pointed to the booth. Julien hesitated. Then he stepped inside and held the receiver to his ear.

"Who is this?" he asked.

A very slow, musical voice answered him. He never for a moment had a doubt as to whose it might be.

"Is this Sir Julien Portel?"

"This is Julien Portel," he answered. "Who is it speaking?"

"I am Henriette Christophor," the voice replied. "I had word from
England, Sir Julien Portel, that you were coming to see me."

"I shall do myself that honor," Julien assured her, "before I leave
Paris."

"You were not polite," the voice continued, "that you did not come this afternoon."

"Madame," Julien said, "I am not here to make acquaintances. It is true that I promised to call upon you; I do not know why, I do not know whom I promised, I do not know for what reason I was asked to come. Since I have promised, however, and you are kind enough to desire it, I will come."

"And why not now?" the voice persisted. "You are alone in Paris, are you not? I have something to say to you, something which is best said quickly."

Julien hesitated.

"You will come?" the voice begged. "My automobile will be at your hotel in ten minutes. You shall come, and if you dislike, after all, to make that call, you shall drive with me, if you prefer it. Monsieur, if you please!"

"I will be ready," Julien answered.

He hung up the receiver and walked out into the hall. He was angry with himself because only an hour ago he had told himself that he would not make that call. He was angry, too, because the fact of his making it or not making it had assumed a ridiculous importance in his eyes.

He walked to the bar and filled his case with cigarettes. Then he took up a monthly magazine and read. His own official resignation was dealt with in a political article of some significance. It interested him curiously. One sentence in particular he read several times:

It is not our desire to play the alarmist, but we would point out to Great Britain that she may at any time within the next few weeks be called upon to face a situation of great gravity, and we cannot help expressing our regret that when that time comes the country should be deprived of the advice, sound judgment and experience of a man who, notwithstanding his youth, has already made his mark in European politics.

Julien flung the paper down. What that situation might be he knew, perhaps, better than any man!

The porter hurried up to him.

"There is a lady outside who inquires for monsieur," he announced.
