The other looked with a quick glance of apprehension at me. “We had better continue our talk in private, Herr Colonel,” he said. “If Herr Brandt will forgive us, we will leave him for a little to entertain himself.” He pushed the cigar-box towards me and the two got up and left the room.

I pulled my chair up to the stove, and would have liked to drop off to sleep. The tension of the talk at supper had made me very tired. I was accepted by these men for exactly what I professed to be. Stumm might suspect me of being a rascal, but it was a Dutch rascal. But all the same I was skating on thin ice. I could not sink myself utterly in the part, for if I did I would get no good out of being there. I had to keep my wits going all the time, and join the appearance and manners of a backveld Boer with the mentality of a British intelligence-officer. Any moment the two parts might clash and I would be faced with the most alert and deadly suspicion.

There would be no mercy from Stumm. That large man was beginning to fascinate me, even though I hated him. Gaudian was clearly a good fellow, a white man and a gentleman. I could have worked with him for he belonged to my own totem. But the other was an incarnation of all that makes Germany detested, and yet he wasn’t altogether the ordinary German, and I couldn’t help admiring him. I noticed he neither smoked nor drank. His grossness was apparently not in the way of fleshly appetites. Cruelty, from all I had heard of him in German South West, was his hobby; but there were other things in him, some of them good, and he had that kind of crazy patriotism which becomes a religion. I wondered why he had not some high command in the field, for he had had the name of a good soldier. But probably he was a big man in his own line, whatever it was, for the Under-Secretary fellow had talked small in his presence, and so great a man as Gaudian clearly respected him. There must be no lack of brains inside that funny pyramidal head.

As I sat beside the stove I was casting back to think if I had got the slightest clue to my real job. There seemed to be nothing so far. Stumm had talked of a von Einem woman who was interested in his department, perhaps the same woman as the Hilda he had mentioned the day before to the Under-Secretary. There was not much in that. She was probably some minister’s or ambassador’s wife who had a finger in high politics. If I could have caught the word Stumm had whispered to Gaudian which made him start and look askance at me! But I had only heard a gurgle of something like “Ühnmantl”, which wasn’t any German word that I knew.

The heat put me into a half-doze and I began dreamily to wonder what other people were doing. Where had Blenkiron been posting to in that train, and what was he up to at this moment? He had been hobnobbing with ambassadors and swells—I wondered if he had found out anything. What was Peter doing? I fervently hoped he was behaving himself, for I doubted if Peter had really tumbled to the delicacy of our job. Where was Sandy, too? As like as not bucketing in the hold of some Greek coaster in the Aegean. Then I thought of my battalion somewhere on the line between Hulluch and La Bassee, hammering at the Boche, while I was five hundred miles or so inside the Boche frontier.

It was a comic reflection, so comic that it woke me up. After trying in vain to find a way of stoking that stove, for it was a cold night, I got up and walked about the room. There were portraits of two decent old fellows, probably Gaudian’s parents. There were enlarged photographs, too, of engineering works, and a good picture of Bismarck. And close to the stove there was a case of maps mounted on rollers.

I pulled out one at random. It was a geological map of Germany, and with some trouble I found out where I was. I was an enormous distance from my goal and moreover I was clean off the road to the East. To go there I must first go to Bavaria and then into Austria. I noticed the Danube flowing eastwards and remembered that that was one way to Constantinople.

Then I tried another map. This one covered a big area, all Europe from the Rhine and as far east as Persia. I guessed that it was meant to show the Baghdad railway and the through routes from Germany to Mesopotamia. There were markings on it; and, as I looked closer, I saw that there were dates scribbled in blue pencil, as if to denote the stages of a journey. The dates began in Europe, and continued right on into Asia Minor and then south to Syria.

For a moment my heart jumped, for I thought I had fallen by accident on the clue I wanted. But I never got that map examined. I heard footsteps in the corridor, and very gently I let the map roll up and turned away. When the door opened I was bending over the stove trying to get a light for my pipe.

It was Gaudian, to bid me join him and Stumm in his study.
