As they came lower the bumping became much worse, so Wash took the aircraft up again to just below cloud level. Even there it was far from comfortable, and every few moments the 'plane dropped like a stone from fifty to a hundred feet. Several times now Wash changed course, and in one case circled right round a giant peak. Then he evidently got his bearings and in a series of shallow dives brought the 'plane right down until it was flying between two ranges of mountains. Turning where they opened out he came back, now perilously skirting great jutting crags. But he was a superb pilot and still seemed perfectly relaxed as he lay back with his long legs stretched out, his great hands firmly on the controls.

It was lighter now. Mary could see the dark woods on the lower slopes, and the green of fields in the bottom of the valley. They passed over a cluster of dwellings, came lower, gently now, and in another minute were running low over a long stretch of meadow. But Wash did not land. In a steep climb he took the 'plane out of the far end of the valley, circled and eame in again, still more slowly. The 'plane bumped once, twice, then ran on smoothly for several hundred yards, until he braked it to a halt in front of an open hangar.

A short, swarthy man with a shock of dark wiry hair ran out from it, followed by two Chinese one of whom was carrying a ladder. Wash stretched a long arm back and undid the clamps of the aircraft's door. The ladder was put against it and, pushing past Mary, the Great Ram stepped out. Seizing his hand, the swarthy man kissed his ring, greeted him in some foreign language and helped him down the last few rungs.

When he had left the aircraft Mary found her voice. She was staring in surprise at the Chinese, and said to Wash, 'Where are we? Surely there are no great mountains like these in Russia. Have you brought us down in . . . no, it couldn't possibly be Tibet; we haven't been in the air long enough.'

He laughed. 'This is Switzerland. We're stopping off here for a day or so on our way to Moscow; that's all.' As he spoke he ducked his head and thrust his great body through the doorway. Springing down, he turned at the foot of the ladder, held out his arms, and told her to jump.
