The Chinaman glided to his side.
“Master,” he said softly, “I have fears. There is something not good in the air.”
Mr. Sabin turned sharply around.
“What do you mean?” he asked.
Foo Cha was apologetic but serious.
“Master, I was followed from the house of the German by a man, who drove fast after me in a two-wheeled cab. He lost me on the way, but there are others. I have been into the street, and I am sure of it. The house is being watched on all sides.”
Mr. Sabin drew a quiet, little breath. For a moment his haggard face seemed almost ghastly. He recovered himself, however, with an effort.
“We are not in China, Foo Cha,” he said. “I have done nothing against the law of this country; no man can enter here if we resist. If we are really being watched, it must be by persons in the pay of the Russian. But they can do nothing; it is too late; Knigenstein will be here in half an hour. The thing will be settled then, once and for ever.”
Foo Cha was troubled still.
