Flooded by the pure light of the moon, the valley appeared a perfect haven of rest. No one would have believed that such a beautiful spot had, in former times, been the scene of such terrible brutality. The tall tower shone like brass, and at its feet the broad waters of the Sang River flowed swiftly to the west.

Ling, still dragging Frank forward, descended the hill, and then turned to the right, towards a clump of trees. It was then, for the first time since they had left Canton, that, of his own accord, he spoke to his prisoner.

"Here is the place," he cried. "The Glade of Children's Tears. Here it is that Cheong-Chau's ransom money will be hidden."

Frank did not think it advisable to answer. Ling no longer held him by a wrist: such a precaution was now unnecessary. Frank could not possibly escape.

For a distance of about a hundred yards they walked in the heavy shadows under the branches of the trees, which were thick with leaves. And then, quite suddenly, they came once again into the bright moonlight, to find themselves confronted by a scene which was both grotesque and picturesque.

In ancient times the place had evidently been the site of a temple, of which only the ruined walls, a few stone steps and several flagstones remained. Here and there, lying upon the ground, overgrown by weeds and underwoods, were great broken, hideous idols, many of which were at least twelve feet in length. In the ghostly moonlight, it was like looking upon a scene which had been the battle-field of giants.

It was manifest that Ling knew the place well, for he walked straight up to a great circular stone, considerably darker in colour than the surrounding brickwork and rocks. Though this stone must have been of enormous weight, he rolled it away without difficulty. Beneath was a large hole. Going down upon his knees, the man struck a match, the light of which dimly illumined a vault as large as an ordinary room.

"Empty!" he exclaimed. "However, I did not expect to find the money here. It should arrive to-morrow, if my calculations are correct. I do not think that your friends will venture to waste time. Too much is at stake."

"My friends?" said Frank.

"Exactly," said the other. "I was so fortunate as to discover who you are. I confess that for days you deceived me. I never dreamt for a moment that the boy whose services I enlisted in Sanshui was a European. I congratulate you upon your accent and your knowledge of the Cantonese language. You speak it as well as I, who am a Northerner."
