All was pandemonium. Women shrieked and fainted; there was a general struggle to get to the doors. Hugh could not move; he was wedged in a mob of players who fought and roared and cursed, as they backed away from the bandits.

Then in the midst of the mad tumult, hushing and dominating it, a harsh metallic voice rang out. “There is no danger so long as no one resists. Go quickly, all of you, and leave the rooms empty.”

It was Doctor Bergius. He was standing on the table to the right, an automatic in either hand. Around his head was bound a white bandage. Suddenly Hugh heard a report near him. A croupier had put his hand on the metal box where the big notes were kept; he collapsed instantly, shot in the head by Castelli.

Hugh was forced with the crowd into the refreshment room. He could still see swarthy ruffians pouring from the small salon and hear shrieks, shots, howls of excitement.

The centre of the Casino had been cleared, hundreds of players had been driven into the atrium, hundreds of others penned in the refreshment room. Doctor Bergius still stood there, while Castelli and two others looted the tables. The band that had worked the private rooms came running back with their booty. They were joined almost immediately by the gang that had been pillaging the main rooms. With revolvers in hands, they formed a solid mass, their eyes flashing, their teeth gleaming ferociously. The voice of Doctor Bergius again rang out:

“Stay where you are, all of you. We have men posted to command the crowd. If one of you moves from his place before a full ten minutes has passed he will be shot. This is a solemn warning.”

The doctor leaped down, and his men followed him, firing as they went.

Hugh edged through the crowd; he wanted to see what was happening. The last of the rear guard had disappeared into the smaller salon. Through the open doorway he saw them descending by the window. No one had as yet dared to move. Yes, there was one, a woman. Hugh saw her run in from the atrium, and marvelled at her daring. Then he recognized her. It was the tall woman who always dressed in grey. As she crossed the threshold of the small salon, she fired at the two men who were balanced on the sill; they swung around and returned the fire. Hugh recognized Castelli and the doctor. Then they, too, disappeared and the woman in grey lay still on the floor.

Everything was quiet, impressively quiet. The ten minutes were up but still no one was inclined to move. Hugh was the first to break the spell. He ran across the empty hall to the nearest open window. Two launches were steaming away. All was over now. The grand coup had been successful. When he turned back, the lackeys were carrying the veiled woman into one of the private rooms. Suddenly Hugh remembered the supposed suicide. He ran into the grand salon. The body still lay under the table. He bent down and examined it. It was Vulning; the false blonde beard was crimsoned with blood, and his head was blown open. The revolver had been loaded with a real ball. The poor devil had put an end to his own life. Doctor Bergius had seen to it that he had saved them his share of the swag. What a joker the doctor was!
