Before he answered the Chief's question, he studied him for a moment under cover of lighting a cigarette. How very little, to be sure, escaped that swift and silent mind! At luncheon the Chief had scrupulously avoided making, the slightest allusion to the thoughts with which Desmond's mind was seething. Instead he had told, with the gusto of the born raconteur, a string of extremely droll yarns about "double crosses," that is, obliging gentlemen who will spy for both sides simultaneously, he had come into contact with during his long and varied career. Desmond had played up to him and repressed the questions which kept rising to his lips. Hence the Chief's unexpected tribute to him in the smoking room,"Well," said Desmond slowly, "there are one or two things Ishould like to know. What am I here for? Why did you have me followed last night? How did you know, before we ever went to Seven Kings, that Barney did not murder old Mackwayte? And lastly..."He paused, fearing to be rash; then he risked it:
"And lastly, Nur-el-Din?"
The Chief leant back in his chair and laughed.
"I'm sure you feel much better now," he said. Then his face grew grave and he added:
"Your last question answers all the others!""Meaning Nur-el-Din?" asked Desmond.
The Chief nodded.
"Nur-el-Din," he repeated. "That's why you're here, that's why Ihad you followed last night, that's why I..." he hesitated for the word, "let's say, presumed (one knows for certain so little in our work) that our friend Barney had nothing to do with the violent death of poor old Mackwayte. Nur-el-Din in the center, the kernel, the hub of everything!"The Chief leant across the table and Desmond pulled his chair closer.
"There's only one other man in the world can handle this job, except you," he began, "and that's your brother Francis. Do you know where he is, Okewood?""He wrote to me last from Athens," answered Desmond, "but that must be nearly two months ago."The Chief laughed.
"His present address is not Athens," he said, "if you want to know, he's serving on a German Staff somewhere at the back of Jerusalem the Golden. Frankly, I know you don't care about our work, and I did my best to get your brother. He has had his instructions and as soon as he can get away he will. That was not soon enough for me. It had to be him or you. So I sent for you."He stopped and cleared his throat. Desmond stared at him. He could hardly believe his eyes. This quiet, deliberate man was actually embarrassed.
"Okewood," the Chief went on, "you know I like plain speaking, and therefore you won't make the mistake of thinking I'm trying to flatter you."Desmond made a gesture.
"Wait a moment and hear me out," the Chief went on. "What is required for this job is a man of great courage and steady nerve.
Yes, we have plenty of fellows like that. But the man I am looking for must, in addition to possessing those qualities, know German and the Germans thoroughly, and when I say thoroughly Imean to the very core so that, if needs be, he may be a German, think German, act German. I have men in my service who know German perfectly and can get themselves up to look the part to the life. But they have never been put to the real, the searching test. Not one of them has done what you and your brother successfully accomplished. The first time I came across you, you had just come out of Germany after fetching your brother away. To have lived for weeks in Germany in wartime and to have got clear away is a feat which shows that both you and he can be trusted to make a success of one of the most difficult and critical missions I have ever had to propose. Francis is not here. That's why Iwant you."
The Chief paused as if weighing something in his mind.
"It's not the custom of either service, Okewood," he said, "to send a man to certain death. You're not in this creepy, crawly business of ours. You're a pukka soldier and keen on your job. So I want you to know that you are free to turn down this offer of mine here and now, and go back to France without my thinking a bit the worse of you.""Would you tell me something about it?" asked Desmond.
"I'm sorry I can't," replied the other. "There must be only two men in this secret, myself and the fellow who undertakes the mission. Of course, it's not certain death. If you take this thing on, you'll have a sporting chance for your life, but that's all. It's going to be a desperate game played against a desperate opponent. Now do you understand why I didn't want you to think Iwas flattering you? You've got your head screwed on right, Iknow, but I should hate to feel afterwards, if anything went wrong, that you thought I had buttered you up in order to entice you into taking the job on!"Desmond took two or three deep puffs of his cigarette and dropped it into the ash-tray.
"I'll see you!" he said.
The Chief grinned with delight.
"By Jove!" he exclaimed, "I knew you were my man!"
