As we talked I had been searching the interior of the chamber with my eyes. It was, perhaps, two hundred feet in length and half as broad, with what appeared to be a doorway in the centre of the wall directly opposite that through which we had entered.
The apartment was hewn from the material of the cliff, showing mostly dull gold in the dim light which a single minute radium illuminator in the centre of the roof diffused throughout its great dimensions. Here and there polished surfaces of ruby, emerald, and diamond patched the golden walls and ceiling. The floor was of another material, very hard, and worn by much use to the smoothness of glass.
Aside from the two doors I could discern no sign of other aperture, and as one we knew to be locked against us I approached the other.
As I extended my hand to search for the controlling button, that cruel and mocking laugh rang out once more, so close to me this time that I involuntarily shrank back, tightening my grip upon the hilt of my great sword.
