He stood swaying half-way between the chair he had left and the alcove, and his trembling finger was pointing at them.

"Stop!" he said in a commanding voice. "Stop! I've got something to say to you. I know ... he's making you pay for the Green Rust...."

So far he got when he reeled and collapsed in a heap on the floor. The doctor sprang forward, lifted him and carried him to the chair by the pillar. He picked up the overcoat that the man had been wearing and spread it over him.

"It's a fainting-fit, nothing to be alarmed about," he said to the little knot of people from the tables who had gathered about the limp figure. "Jaques"—he called the head-waiter—"get some brandy, he must be kept warm."

"Shall I ring for an ambulance, m'sieur?"

"It is not necessary," said van Heerden. "He will recover in a few moments. Just leave him," and he walked back to the alcove.

"Who is he?" asked the girl, and her voice was shaking in spite of herself.

"He is a man I knew in his better days," said van Heerden, "and now I think you must go."

"I would rather wait to see if he recovers," she said with some obstinacy.
