“I might have guessed it!” he told himself with considerable pleasure, as he switched to high power. So last night's show had impressed Morgan, as well it should have done. The engineer was seeing for himself, in the short time available, how Kalidasa's architects had met the challenge imposed upon them.

Then Rajasinghe noticed something quite alarming. Morgan was walking briskly around at the very edge of the plateau, only centimetres away from the sheer drop that few tourists ever dared to approach. Not many had the courage even to sit in the Elephant Throne, with their feet dangling over the abyss; but now the engineer was actually kneeling beside it, holding on to the carved stonework with one casual arm – and leaning right out into nothingness as he surveyed the rock-face below. Rajasinghe, who had never been very happy even with such familiar heights as Yakkagala's, could scarcely bear to watch.

After a few minutes of incredulous observation, he decided that Morgan must be one of those rare people who are completely unaffected by heights. Rajasinghe's memory, which was still excellent but delighted in playing tricks on him, was trying to bring something to his notice. Hadn't there once been a Frenchman who had tightroped across Niagara Falls, and even stopped in the middle to cook a meal? If the documentary evidence had not been overwhelming, Rajasinghe would never have believed such a story.
