"I've done it already, sir," he told him, with a grin. "You see, Major Douglas—who's an Indian 'political', and who happens to be my guardian—brought me to Mesopotamia some while ago, and we went right into the heart of the country. The Major knows all sorts of Arabs and other people, and it's part of his job—or was, at any rate, in peace times—to find out everything that was going on; what the Turks were doing, what the Arabs thought of them, and how the various nationalities lived."

"Half a minute!" smiled the Commander. "What about the Germans?"

"Germans! Of course," admitted Geoff, "they were to be met with in all sorts of odd corners, and conducting every sort of extraordinary business. My suspicion is that their businesses, on many occasions, were absolutely fictitious; in fact, they had no real business in many cases, and were simply agents of the German Government sent into the country to worm out the secrets of the Turks, and more particularly to find out precisely what opportunities there were for trade, and what portion of it the British had secured."

"Hear! Hear!" echoed the Commander. "You can quite understand that being ordered to the Persian Gulf, and having to steam up and down that extremely uninteresting, not to say unhealthy part, left a man plenty of time for ruminating, for discussing matters in general, and for learning in particular something of what was happening in this portion of Turkey and in Persia. A fellow couldn't steam up to Basra—as we did now and again in one of our pinnaces—without knocking up against Germans—fat Germans, thin Germans, ugly Germans (lots of ugly ones, my boy)—Germans who were conducting some sort of trade, and who appeared at first sight to be the most harmless and almost the most helpless people under the sun. But that's your wily German all over!

"I remember one particular individual—a big, fat, jovial fellow—Von something or other, I've forgotten his name, except that it was a regular 'jaw-cracker'. Von Schmidt let's call him for the moment. A nicer chap to meet you couldn't wish for, that is, just at the beginning. I remember that he was trying to get together a business in dates. His sole object in life seemed to be that of bribing Arabs to bring in camel-loads of dates, and to deposit them in an old hut which he had hired just on the outskirts of Basra; and now and again he sent off a barge full of these same dates, consigning them to some place in Europe. But it was not his real business, my boy! And I found that out quite by accident. For, happening to get stranded one evening when darkness had fallen, and in the midst of a violent rain-storm, I claimed shelter from him—for there was a light in the window of his house. It was blowing big guns just then, and I suppose he didn't hear the rap I gave on the door. As a matter of fact, he was in his bedroom, which was at the back of the building. It wasn't the sort of time when one waits for a summons, for the rain was pouring down in torrents, as I told you, so I just pushed the door open and went into the main room of the building, and, shutting the door, shouted for him. Even then he didn't hear, so that I had time to take a good look round, and couldn't help seeing that the table in the centre of the room was piled with papers, and that maps—maps of Mesopotamia, maps of the Persian Gulf—diagrams showing the 'pipe-line', which brings our oil from Persia, and lists of Arab tribes, against which was placed a note in German, which showed that they were to be considered friendly, were spread out over the remaining portion of the table. You see," he added, with a chuckle, "I know a little German. Not much, you know, but just sufficient to read it. I can't tell you now all about those papers, and of course it isn't quite the thing for a man to enter the house of an acquaintance and read his private correspondence. It isn't 'cricket', of course, you know, and no Britisher does it; but accidents will happen, and that night it so fell out that my eyes were unwittingly opened: the fat, pleasant, jovial Von what's-his-name was undoubtedly a German Government agent."

Geoff nodded briskly, for he and Major Douglas had had many an experience with German agents in Mesopotamia.

"I don't profess to know all about it, sir," he told the Commander, "but the Major was very chary of the Germans he met, and often told me that Germany undoubtedly had her eyes on Asiatic Turkey, and was preparing the ground for some future occasion. But you were saying that I could dress up as a Turk and move about amongst them. I've done it, sir! You must understand that the Germans in Mesopotamia were very jealous of the Major, they not only suspected him to be a British agent, but knew what his mission was in the country, and for that reason set a watch on him. They bribed men to follow us, and put the Turks on our tracks, so that had we not been very quick and very wide awake we should have learned nothing—that is to say, the Major would have learned nothing—for the British Government. We had to give the Germans and the Turks the slip, and we did it, time and again, by adopting a disguise and moving off amongst the people. But about this native, sir; you suggested that he should be cross-examined."

"That's it!" cried the Commander, filling his pipe again. "Call the old boy up! 'Pon my word, now that one looks at him, he's quite a handsome scoundrel!"

By then the men for'ard, and the native whom they had been entertaining, had finished their meal, and, like their officer, were enjoying a quiet smoke before pushing onward. Sailor-like, too, they were endeavouring to their utmost to make themselves pleasant to their passenger. It was quite amusing to watch a big, burly sailor discoursing eloquently to the native and listening intently; Geoff and Philip and their Commanding Officer overheard some of this conversation.

"Look 'ere, old soul," they heard the A.B. exclaim in the most friendly fashion, while he tapped the native on his bare chest, "what's the use of this 'ere place at all? This 'ere Mesopotamia? What's the good of a country that's all sand and grit, with no good and decent water about it? Now, I could tell you of a country that's worth seeing! Know England, my lad?"
