She frowned.

"How do you mean?"

"How shall I put it? I can't work. I can't think. In my stuff one has to have a high degree of concentration. A lot of it is - well - creative. have a high degree of concentration. A lot of it is - well - creative. Since coming here I've just lost the urge. All I can do is good sound Since coming here I've just lost the urge. All I can do is good sound hack work.

But that's not what they brought me here for. They want original stuff and I can't do original stuff. And the more want original stuff and I can't do original stuff. And the more nervous and afraid I get, the less I'm fit to turn out anything worth nervous and afraid I get, the less I'm fit to turn out anything worth turning out. And it's driving me off my rocker, do you see?" turning out. And it's driving me off my rocker, do you see?"

Yes, she saw now. She recalled Dr. Rubec's remarks about prima donnas and scientists. donnas and scientists.

"If I can't deliver the goods, what is an outfit like this going to do about it? They'll liquidate me." about it? They'll liquidate me."

"Oh no."

"Oh yes they will. They're not sentimentalists here. What's saved me so far is this plastic surgery business. They do it a little at a me so far is this plastic surgery business. They do it a little at a time, you know. And naturally a fellow who's having constant minor time, you know. And naturally a fellow who's having constant minor operations can't be expected to concentrate. But they've finished operations can't be expected to concentrate. But they've finished the business now." the business now."

"But why was it done at all? What's the point?"

"Oh, that! For safety. My safety, I mean. It's done if - if you're a 'wanted' man."

"Are you a 'wanted' man, then?"

"Yes, didn't you know? Oh, I suppose they wouldn't advertise the fact in the papers. Perhaps even Olive didn't know. But I'm wanted fact in the papers. Perhaps even Olive didn't know. But I'm wanted right enough." right enough."

"You mean for - treason is the word, isn't it? You mean you've sold them atom secrets?" them atom secrets?"

He avoided her eyes.

"I didn't sell anything. I gave them what I knew of our processes - gave it freely. If you can believe me, I wanted to give it to them. It gave it freely. If you can believe me, I wanted to give it to them. It was part of the whole setup - the pooling of scientific knowledge. was part of the whole setup - the pooling of scientific knowledge. Oh, can't you understand?" Oh, can't you understand?"

She could understand. She could understand Andy Peters doing just that. She could see Ericsson with his fanatical dreamer's eyes just that. She could see Ericsson with his fanatical dreamer's eyes betraying his country with a high-souled enthusiasm. betraying his country with a high-souled enthusiasm.

Yet it was hard for her to visualise Tom Betterton doing it - and she realised with a shock that all that showed was the difference realised with a shock that all that showed was the difference between Betterton a few months ago, arriving in all the zeal of between Betterton a few months ago, arriving in all the zeal of enthusiasm, and Betterton now, nervous, defeated, down to earth - enthusiasm, and Betterton now, nervous, defeated, down to earth - an ordinary badly frightened man. an ordinary badly frightened man.

Even as she accepted the logic of that, Betterton looked round him nervously and said: nervously and said: "Everyone's gone down. We'd better -"

She rose.

"Yes. But it's all right, you know. They'll think it quite natural - under the circ.u.mstances." the circ.u.mstances."

He said awkwardly: "We'll have to go on with this now, you know. I mean - you'll have to go on being - my wife." go on being - my wife."

"Of course."

"And we'll have to share a room and all that. But it will be quite all right. I mean, you needn't be afraid that -" right. I mean, you needn't be afraid that -"

He swallowed in an embarra.s.sed manner.

"How handsome he is," thought Hilary, looking at his profile, "and how little it moves me..." how little it moves me..."

"I don't think we need worry about that," she said cheerfully. "The important thing is to get out of here alive." important thing is to get out of here alive."

Chapter 14.

In a room at the Hotel Mamounia, Marrakesh, the man called Jessop was talking to Miss Hetherington. A different Miss Hetherington was talking to Miss Hetherington. A different Miss Hetherington this, from the one that Hilary had known at Casablanca and at Fez. this, from the one that Hilary had known at Casablanca and at Fez. The same appearance, the same twin set, the same depressing The same appearance, the same twin set, the same depressing hair-do. But the manner had changed. It was a woman now both hair-do. But the manner had changed. It was a woman now both brisk, competent, and seeming years younger than her brisk, competent, and seeming years younger than her appearance.

The third person in the room was a dark stocky man with intelligent eyes. He was tapping gently on the table with his fingers and eyes. He was tapping gently on the table with his fingers and humming a little French song under his breath. humming a little French song under his breath.

"... and as far as you know," Jessop was saying, "those are the only people she talked to at Fez?" people she talked to at Fez?"

Janet Hetherington nodded.

"There was the Calvin Baker woman, whom we'd already met at Casablanca. I'll say frankly I still can't make up my mind about her. Casablanca. I'll say frankly I still can't make up my mind about her. She went out of her way to be friendly with Olive Betterton, and with She went out of her way to be friendly with Olive Betterton, and with me for that matter. But Americans are friendly, they do enter into me for that matter. But Americans are friendly, they do enter into conversation with people in hotels, and they like joining them on conversation with people in hotels, and they like joining them on trips." trips."

"Yes," said Jessop, "it's all a little too overt for what we're looking for." for."

"And besides," went on Janet Hetherington, "she was on this plane, too." too."

"You're a.s.suming," said Jessop, "that the crash was planned." He looked sideways towards the dark, stocky man. "What about it, looked sideways towards the dark, stocky man. "What about it, Leblanc?" Leblanc?"

Leblanc stopped humming his tune, and stopped his little tattoo on the table for a moment or two. the table for a moment or two.

" ala ce peut," he said. "There may have been sabotage to the machine and that is why it crashed. We shall never know. The plane machine and that is why it crashed. We shall never know. The plane crashed and went up in flames and everyone on board was killed." crashed and went up in flames and everyone on board was killed."

"What do you know of the pilot?"

"Alcadi? Young, reasonably competent. No more. Badly paid." He added the two last words with a slight pause in front of them. added the two last words with a slight pause in front of them.

Jessop said: "Open therefore to other employment, but presumably not a candidate for suicide?" candidate for suicide?"

"There were seven bodies," said Leblanc. "Badly charred, unrecognisable, but seven bodies. One cannot get away from that." unrecognisable, but seven bodies. One cannot get away from that."

Jessop turned back to Janet Hetherington.

"You were saying?" he said.

"There was a French family at Fez that Mrs. Betterton exchanged a few words with. There was a rich Swedish business man with a few words with. There was a rich Swedish business man with a glamour girl. And the rich oil magnate, Mr. Aristides." glamour girl. And the rich oil magnate, Mr. Aristides."

"Ah," said Leblanc, "that fabulous figure himself. What must it feel like, I have often asked myself, to have all the money in the world? like, I have often asked myself, to have all the money in the world?

For me," he added frankly, "I would keep race horses and women, and all the world has to offer. But old Aristides shuts himself up in and all the world has to offer. But old Aristides shuts himself up in his castle in Spain - literally his castle in Spain, mon cher - and his castle in Spain - literally his castle in Spain, mon cher - and collects, so they say, Chinese potteries of the Sung period. But one collects, so they say, Chinese potteries of the Sung period. But one must remember," he added, "that he is at least seventy. It is must remember," he added, "that he is at least seventy. It is possible at that age that Chinese potteries are all that interest one." possible at that age that Chinese potteries are all that interest one."

"According to the Chinese themselves," said Jessop, "the years between sixty and seventy are the most rich in living and one is then between sixty and seventy are the most rich in living and one is then most appreciative of the beauty and delight of life." most appreciative of the beauty and delight of life."

"Pas moi!" said Leblanc.

"There were some Germans at Fez, too," continued Janet Hetherington, "but as far as I know they didn't exchange any Hetherington, "but as far as I know they didn't exchange any remarks with Olive Betterton." remarks with Olive Betterton."

"A waiter or a servant, perhaps," said Jessop.

"That's always possible."

"And she went out into the old town alone, you say?"

"She went with one of the regular guides. Someone may have contacted her on that tour." contacted her on that tour."

"At any rate she decided quite suddenly to go to Marrakesh."

"Not suddenly," she corrected him. "She already had her reservations." reservations."

"Ah, I'm wrong," said Jessop. "What I mean is that Mrs. Calvin Baker decided rather suddenly to accompany her." He got up and Baker decided rather suddenly to accompany her." He got up and paced up and down. "She flew to Marrakesh," he said, "and the paced up and down. "She flew to Marrakesh," he said, "and the plane crashed and came down in flames. It seems ill-omened, does plane crashed and came down in flames. It seems ill-omened, does it not, for anyone called Olive Betterton to travel by air. First the it not, for anyone called Olive Betterton to travel by air. First the crash near Casablanca, and then this one. Was it an accident or crash near Casablanca, and then this one. Was it an accident or was it contrived? If there were people who wished to get rid of Olive was it contrived? If there were people who wished to get rid of Olive Betterton, there would be easier ways to do it than by wrecking a Betterton, there would be easier ways to do it than by wrecking a plane, I should say." plane, I should say."

"One never knows," said Leblanc. "Understand me, mon cher. Once you have got into that state of mind where the taking of Once you have got into that state of mind where the taking of human lives no longer counts, then if it is simpler to put a little human lives no longer counts, then if it is simpler to put a little explosive package under a seat in a plane, than to wait about at the explosive package under a seat in a plane, than to wait about at the corner on a dark night and stick a knife into someone, then the corner on a dark night and stick a knife into someone, then the package will be left and the fact that six other people will die also is package will be left and the fact that six other people will die also is not even considered." not even considered."

"Of course," said Jessop, "I know I'm in a minority of one, but I still think there's a third solution - that they faked the crash." think there's a third solution - that they faked the crash."

Leblanc looked at him with interest.

"That could be done, yes. The plane could be brought down and it could be set on fire. But you cannot get away from the fact, mon could be set on fire. But you cannot get away from the fact, mon cher Jessop, that there were people in the plane. The charred cher Jessop, that there were people in the plane. The charred bodies were actually there." bodies were actually there."

"I know," said Jessop. "That's the stumbling block. Oh, I've no doubt my ideas are fantastic, but it's such a neat ending to our hunt. doubt my ideas are fantastic, but it's such a neat ending to our hunt. Too neat. That's what I feel. It says finish to us. We write down R.I.P. Too neat. That's what I feel. It says finish to us. We write down R.I.P. in the margin of our report and it's ended. There's no further trail to in the margin of our report and it's ended. There's no further trail to take up." He turned again to Leblanc. "You are having that search take up." He turned again to Leblanc. "You are having that search inst.i.tuted?" inst.i.tuted?"

"For two days now," said Leblanc. "Good men, too. It's a particularly lonely spot, of course, where the plane crashed. It was particularly lonely spot, of course, where the plane crashed. It was off its course, by the way." off its course, by the way."

"Which is significant," Jessop put in.

"The nearest villages, the nearest habitations, the nearest traces of a car, all those are being investigated fully. In this country as well a car, all those are being investigated fully. In this country as well as in yours, we fully realise the importance of the investigation. In as in yours, we fully realise the importance of the investigation. In France, too, we have lost some of our best young scientists. In my France, too, we have lost some of our best young scientists. In my opinion, mon cher, it is easier to control temperamental opera opinion, mon cher, it is easier to control temperamental opera singers than it is to control a scientist.

Sweetness and light and desire for truth and the millennium?

Alas, poor children, what disillusionment awaits them."

"Let's go over the pa.s.senger list once more," said Jessop.

The Frenchman reached out a hand, picked it out of a wire basket and set it before his colleague. The two men pored over it together. and set it before his colleague. The two men pored over it together.

"Mrs. Calvin Baker, American. Mrs. Betterton, English. Torquil Ericsson, Norwegian - what do you know of him, by the way?" Ericsson, Norwegian - what do you know of him, by the way?"

"Nothing that I can recall," said Leblanc. "He was young, not more than twenty-seven or twenty-eight." than twenty-seven or twenty-eight."

"I know his name," said Jessop, frowning. "I think - I am almost sure -that he read a paper before the Royal Society."

"Then there is the religieuse," Leblanc said, turning back to the list.

"Sister Marie something or other. Andrew Peters, also American. Dr. Barron. That is a celebrated name, le doctor Barron. A man of Dr. Barron. That is a celebrated name, le doctor Barron. A man of great brilliance. An expert on virus diseases." great brilliance. An expert on virus diseases."

"Biological warfare," said Jessop. "It fits. It all fits."

"A man poorly paid and discontented," said Leblanc.

"How many going to St. Ives?" murmured Jessop.

The Frenchman shot him a quick look and he smiled apologetically.

"Just an old nursery rhyme," he said. "For St. Ives read question mark. Journey to nowhere." mark. Journey to nowhere."

The telephone on the table buzzed and Leblanc picked up the receiver. receiver.

"Allo?" he said. "Qu'est ce qu'il y a? Ah, yes, send them up." He turned his head towards Jessop. His face was suddenly alive, turned his head towards Jessop. His face was suddenly alive, vigorous. "One of my men reporting," he said. "They have found vigorous. "One of my men reporting," he said. "They have found something. Mon cher collegue, it is possible - I say no more - something. Mon cher collegue, it is possible - I say no more - possible that your optimism is justified." possible that your optimism is justified."

A few moments later two men entered the room. The first bore a rough resemblance to Leblanc, the same type, stocky, dark, rough resemblance to Leblanc, the same type, stocky, dark, intelligent. His manner was respectful but exhilarated. He wore intelligent. His manner was respectful but exhilarated. He wore European clothes badly stained and marked, covered with dust.

With him was a native wearing the white local dress. He had the dignified composure of wearing the white local dress. He had the dignified composure of the dweller in remote places. His manner was courteous but not the dweller in remote places. His manner was courteous but not subservient. He looked with a faint wonder round the room whilst subservient.

"The reward was offered and circulated," the man explained, "and this fellow and his family and a great many of his friends have been this fellow and his family and a great many of his friends have been searching diligently. I let him bring you the find himself as there searching diligently. I let him bring you the find himself as there may be questions you want to ask him." may be questions you want to ask him."

Leblanc turned to the Berber - "You have done good work," he said, speaking now in the man's own language. "You have the eyes of the hawk, my father. Show us own language. "You have the eyes of the hawk, my father. Show us then what you have discovered." then what you have discovered."

From a fold in his white robe the man took out a small object, and stepping forward laid it on the table before the Frenchman. It was stepping forward laid it on the table before the Frenchman. It was rather a large sized pinkish grey synthetic pearl. rather a large sized pinkish grey synthetic pearl.

"It is like the one shown to me and shown to others," he said. "It is of value and I have found it." of value and I have found it."

Jessop stretched out a hand and took the pearl. From his pocket he drew out another exactly like it and examined both. Then he walked drew out another exactly like it and examined both. Then he walked across the room to the window, and examined them both through a across the room to the window, and examined them both through a powerful lens. powerful lens.

"Yes," he said, "the mark is there." There was jubilation now in his voice and he came back to the table. "Good girl," he said, "good voice and he came back to the table. "Good girl," he said, "good girl, good girl! She managed it!" girl, good girl! She managed it!"

Leblanc was questioning the Berber in a rapid exchange of Arabic. Finally he turned to Jessop. Finally he turned to Jessop.

"I make my apologies, mon cher collegue," he said. "This pearl was found at a distance of nearly half a mile from the flaming plane." found at a distance of nearly half a mile from the flaming plane."

"Which shows," said Jessop, "that Olive Betterton was a survivor, and that though seven people left Fez in the plane and seven and that though seven people left Fez in the plane and seven charred bodies were found, one of those charred bodies was charred bodies were found, one of those charred bodies was definitely not hers." definitely not hers."

"We extend the search now," said Leblanc. He spoke again to the Berber and the man smiled back happily. He left the room with the Berber and the man smiled back happily. He left the room with the man who had brought him in. "He will be handsomely rewarded as man who had brought him in. "He will be handsomely rewarded as promised," said Leblanc, "and there will be a hunt now all over the promised," said Leblanc, "and there will be a hunt now all over the countryside for these pearls. They have hawk eyes, these people, countryside for these pearls. They have hawk eyes, these people, and the knowledge that these are worth good money in reward will and the knowledge that these are worth good money in reward will pa.s.s round like a grapevine.

If only they have not tumbled to what she was we shall get results! If only they have not tumbled to what she was doing." doing."

Jessop shook his head.

"It would be such a natural occurrence," he said. "The sudden breaking of a necklace of costume jewellery such as most women breaking of a necklace of costume jewellery such as most women wear, the picking up apparently of what loose pearls she can find wear, the picking up apparently of what loose pearls she can find and stuffing them into her pocket, then a little hole in the pocket. and stuffing them into her pocket, then a little hole in the pocket. Besides, why should they suspect her? She is Olive Betterton, Besides, why should they suspect her? She is Olive Betterton, anxious to join her husband." anxious to join her husband."

"We must review this matter in a new light," said Leblanc. He drew the pa.s.senger list towards him. "Olive Betterton. Dr. Barron," he the pa.s.senger list towards him. "Olive Betterton. Dr. Barron," he said, ticking off the two names. "Two at least who are going - said, ticking off the two names. "Two at least who are going - wherever they are going.

How in flames and inside it the requisite number of charred bodies. How did they manage that, I wonder? Enfin, c'est colossal!" did they manage that, I wonder? Enfin, c'est colossal!"

"Yes," said Jessop. "It was the final convincing touch. But we know now that six or seven people have started off on a fresh journey, now that six or seven people have started off on a fresh journey, and we know where their point of departure is. What do we do next - and we know where their point of departure is. What do we do next - visit the spot?" visit the spot?"

"But precisely," said Leblanc. "We take up advanced headquarters. If I mistake not, now that we are on the track, other evidence will If I mistake not, now that we are on the track, other evidence will come to light." come to light."

"If our calculations are exact," Leblanc said, "there should be results." results."

The calculations were many and devious. The rate of progress of a car, the likely distance where it would refuel, possible villages car, the likely distance where it would refuel, possible villages where travellers might have stayed the night. The tracks were where travellers might have stayed the night. The tracks were many and confusing, disappointments were continual, but every many and confusing, disappointments were continual, but every now and then there came a positive result. now and then there came a positive result.
