Lewis was busy turning over the problem in his mind. The presence of the man Holm seemed the one link of proof he needed. He had his word that there were signs of trouble in the place, and that the Bada-Mawidi were ill at ease. Whatever game Marker was playing, on this matter he seemed to have spoken in good faith. Here was a clear piece of work for him. And even if it was fruitless it would bring him nearer to the frontier; his expedition to the north would be begun. "Let me go," he said. "I came out here to explore the hills and I take all risks on my own head. I can give them Marker's message as well as anybody else." Thwaite looked at Holm. "I don't see why he shouldn't. You're a wreck, and I can't leave my own place." "Tell Andy you saw me," cried Holm. "He'll be anxious. And tell him to mind the north gate. If the fools knew how to use dynamite they might have it down at once. If they attack it can't last long, but then they can't last long either, for they are hard up for arms, and unless they have changed since last week they have no ammunition to speak of." "Marker said it looked as if they were being put up to the job from over the frontier." "Gad, then it's my turn to look out," said Thwaite. "If it's the gentlemen from over the frontier they won't stop at Forza. Lord, I hate this border business, it's so hideously in the dark. But I think that's all rot. Any tribal row here is sure to be set down to Russian influence. We don't understand the joint possession of an artificial frontier," he added, with an air of quoting from some book. "Did you get that from Marker?" Holm asked crossly. "He once said the same thing to me." His temper had suffered badly among the hills. "We'd better get you to bed, my dear fellow," said Thwaite, looking down at him. "You look remarkably cheap. Would you mind going in and trying to find Mrs. Logan, Haystoun? I'll carry this chap in. Stop a minute, though. Perhaps he's got something to say to you." "Mind the north gate ... tell Andy I'm all right and make him look after himself ... he's overworking ... if you want to send a message to the other people you'd better send by Nazri ... if the Badas mean business they'll shut up the road you go by. That's all. Good luck and thanks very much." Lewis found Mrs. Logan making a final inspection of the supper-room. She ran to the garden, to find the invalid Holm in Thwaite's arms at the steps of the verandah. The sick warrior pulled off an imaginary cap and smiled feebly. "Oh, Mr. Holm, I'm so sorry. Of course we can have you. I'll put you in the other end of the house where you won't be so much troubled with the noise. You must have had a dreadful journey." And so forth, with the easy condolences of a kind woman. When Thwaite had laid down his burden, he turned to Lewis.
