moved uneasily in his seat. Somehow or other he was determined to get back to Berlin. He could, of course, let Freddie Charlton fly him home, lie up for four days and arrange to be flown out again to the secret landing-ground on the following Sunday night but in the meantime anything might happen and the one thought that agitated his now active mind was the awful danger in which his beloved Erika stood. Tonight Berlin was in utter confusion; almost certainly the street-fighting would still be in progress tomorrow. While the Germans were killing one another they would be much too occupied to do any spy-hunting. If only he could return at once he would be able to move about the city freely, for some hours at least, without being called on to produce any papers. While von Pleisenâs officers were still holding their own he would be able to get in touch with some of those he had met and, since many of them knew Erika, ascertain through them the most likely places in which to look for her. On the other hand, if he could get back to Berlin before Monday morning a decision would almost certainly have been reached by then. If the Generals had come out on top there would be nothing for him to worry about; but he was now extremely dubious about their chances, and if the revolt had been suppressed the old Nazi tyranny would be clamped down more firmly than ever before. Storm-Troopers and police would be challenging all who dared to put their noses out of doors, and without papers his arrest would be certain before he had been back in the Capital an hour. There was no question about it; his only hope of rejoining Erika lay in returning to Berlin while the fighting was still going on. That meant that he must land in Germany again that night, and every mile further that he allowed Charlton to fly him from the Capital would make his task of getting back there moredifficult. He began to plead againâurgentlyâdesperatelyâbut Charlton continued adamant in his refusal. At last Gregory fell silent, but that did not mean that he had abandoned his project. Instead he had begun to contemplate desperate measuresâno less than an attempt to render Charlton powerless and take charge of the plane himself. He felt confident that if he could get control of the plane he knew enough of aircraft to get the machine down without allowing it to plunge headlong to destruction. Landing was another matter. He did not flatter himself for a second that he could perform such an operation successfully when an ace pilot like Charlton declared that in the black-out a crash was inevitable; but modern planes are stoutly built so Gregory was prepared for a crash and to take a chance that if he could bring the plane down slowly with its engine shut off, once it had hit the ground, he would be able to get Charlton and himself clear of it without serious injury. The idea was semi-suicidal and Gregory realised that it was extremely hard on Charlton that his life and freedom should be jeopardised by such an act; but if the airman would not help him by attempting to land of his own free will he must take the consequences. Gregory had risked his neck too often to worry about himself and now the only thing he cared to live for was Erika von Epp. Leaning forward he peered down towards the hidden landscape in an attempt to assess the density of the darkness. For a few moments he could see nothing because they were flying high above a heavy cloud-bank, but after a little the clouds broke and far below he caught sight of a few tiny pin-points of light. The German black-out was still far from perfect. In spite of heavy penalties for slackness there had been a natural tendency to be careless about A.R.P. as the only enemy planes which had flown over the country since the outbreak of war had dropped leaflets instead of bombs. The lights suddenly disappeared again but Gregory reckoned that once below the cloud-bank he would be able to pick up plenty more. The
