Inspector Kelly placed the key in the lock of the door.
It was at this moment that Gaston Max, climbing up to the front balcony by means of the natural ladder afforded by the ancient ivy, grasped the iron railing and drew himself up to the level of the room. By this same stairway Chunda Lal had ascended to death and Miska had climbed down to life.
"Mind the ironwork doesn't give way, sir!" called Dunbar from below.
"It is strong," replied Max. "Join me here, my friend."
Max, taking a magazine pistol from his pocket, stepped warily over the ledge into the mysterious half-light behind the great screen. As he did so, one of the lacquer doors was unlocked from the outside, and across the extraordinary, smoke-laden room he saw Inspector Kelly enter. He saw something else.
Seated in a strangely-shaped canopied chair was a figure wearing a rich mandarin robe, but having its face covered with a green veil.
"Mon Deiu! at last!" he cried, and leapt into the room. "'The Scorpion'!"
Even as he leapt, and as the Scotland Yard men closed in upon the chair also, all of them armed and all half fearful, a thing happened which struck awe to every heart—for it seemed to be supernatural.
Raising a metal hammer which he held in his hand, Fo-Hi struck the bronze bell hung beside the chair. It emitted a deep, loud note….
There came a flash of blinding light, and intense crackling sound, the crash of broken glass, and a dense cloud of pungent fumes rose in the heated air.
