“What has happened now?” said Graham, puzzled, for he could not understand their thick speech.  Then he heard it in English and perceived that the thing that everyone was shouting, that men yelled to one another, that women took up screaming, that was passing like the first breeze of a thunderstorm, chill and sudden through the city, was this:  “Ostrog has ordered the Black Police to London.  The Black Police are coming from South Africa....  The Black Police.  The Black Police.”

Asano’s face was white and astonished; he hesitated, looked at Graham’s face, and told him the thing he already knew.  “But how can they know?” asked Asano.

Graham heard someone shouting.  “Stop all work.  Stop all work,” and a swarthy hunchback, ridiculously gay in green and gold, came leaping down the platforms toward him, bawling again and again in good English, “This is Ostrog’s doing, Ostrog the Knave!  The Master is betrayed.”  His voice was hoarse and a thin foam dropped from his ugly shouting mouth.  He yelled an unspeakable horror that the Black Police had done in Paris, and so passed shrieking, “Ostrog the Knave!”

For a moment Graham stood still, for it had come upon him again that these things were a dream.  He looked up at the great cliff of buildings on either side, vanishing into blue haze at last above the lights, and down to the roaring tiers of platforms, and the shouting, running people who were gesticulating past.  “The Master is betrayed!” they cried.  “The Master is betrayed!”

Suddenly the situation shaped itself in his mind real and urgent.  His heart began to beat fast and strong.

“It has come,” he said.  “I might have known.  The hour has come.”

He thought swiftly.  “What am I to do?”

“Go back to the Council House,” said Asano.

“Why should I not appeal—?  The people are here.”

“You will lose time.  They will doubt if it is you.  But they will mass about the Council House.  There you will find their leaders.  Your strength is there—­with them.”

“Suppose this is only a rumour?”

“It sounds true,” said Asano.

“Let us have the facts,” said Graham.

Asano shrugged his shoulders.  “We had better get towards the Council House,” he cried.  “That is where they will swarm.  Even now the ruins may be impassable.”

Graham regarded him doubtfully and followed him.

They went up the stepped platforms to the swiftest one, and there Asano accosted a labourer.  The answers to his questions were in the thick, vulgar speech.

“What did he say?” asked Graham.

“He knows little, but he told me that the Black Police would have arrived here before the people knew—­had not someone in the Wind-Vane Offices learnt.  He said a girl.”

“A girl?  Not—?”

“He said a girl—­he did not know who she was.  Who came out from the Council House crying aloud, and told the men at work among the ruins.”
