"What's that?"

Colin Camber merely shrugged his shoulders.

"I will repeat my question," said the Inspector, pompously. "Where did you first meet Colonel Juan Menendez?"

"I have answered you, Inspector."

"Oh, I see. You decline to answer that question. Very well, I will make a note of this." He did so. "And now," said he, "what were you doing at midnight last night?"

"I was writing."

"Where?"

"Here."

"What happened?"

Very succinctly Colin Camber repeated the statement which he had already made to Paul Harley, and, at its conclusion:

"Send for the man, Ah Tsong," directed Inspector Aylesbury.

Colin Camber inclined his head, clapped his bands, and silently Ah Tsong entered.

The Inspector stared at him for several moments as a visitor to the Zoo might stare at some rare animal; then:

"Your name is Ah Tsong?" he began.

"Ah Tsong," murmured the Chinaman.

"I am going to ask you to give an exact account of your movements last night."

"No sabby."

Inspector Aylesbury cleared his throat.

"I say I wish to know exactly what you did last night. Answer me."

Ah Tseng's face remained quite expressionless, and:

"No sabby," he repeated.

"Oh, I see," said the Inspector, "This witness refuses to answer at all."

"You are wrong," explained Colin Camber, quietly. "Ah Tsong is a Chinaman, and his knowledge of English is very limited. He does not understand you."

"He understood my first question. You can't draw wool over my eyes. He knows well enough. Are you going to answer me?" he demanded, angrily, of the Chinaman.

"No sabby, master," he said, glancing aside at Colin Camber. "Number- one p'licee-man gotchee no pidgin."

Paul Harley was leisurely filling his pipe, and:

"If you think the evidence of Ah Tsong important, Inspector," he said, "I will interpret if you wish."

"You will do what?"

"I will act as interpreter."

"Do you want me to believe that you speak Chinese?"

"Your beliefs do not concern me, Inspector; I am merely offering my services."

"Thanks," said the Inspector, dryly, "but I won't trouble you. I should like a few words with Mrs. Camber."

"Very good."

Colin Camber bent his head gravely, and gave an order to Ah Tsong, who turned and went out.

"And what firearms have you in the house?" asked Inspector Aylesbury.

"An early Dutch arquebus, which you see in the corner," was the reply.

"That doesn't interest me. I mean up-to-date weapons."

"And a Colt revolver which I have in a drawer here."

As he spoke, Colin Camber opened a drawer in his desk and took out a heavy revolver of the American Army Service pattern.

"I should like to examine it, if you please."

Camber pa.s.sed it to the Inspector, and the latter, having satisfied himself that none of the chambers were loaded, peered down the barrel, and smelled at the weapon suspiciously.

"If it has been recently used it has been well cleaned," he said, and placed it on a cabinet beside him. "Anything else?"

"Nothing."

"No sporting rifles?"

"None. I never shoot."

"Oh, I see."

The door opened and Mrs. Camber came in. She was very simply dressed, and looked even more child-like than she had seemed before. I think Ah Tsong had warned her of the nature of the ordeal which she was to expect, but her wide-eyed timidity was nevertheless pathetic to witness.

She glanced at me with a ghost of a smile, and:

"Ysola," said Colin Camber, inclining his head toward me in a grave gesture of courtesy, "Mr. Knox has generously forgiven me a breach of good manners for which I shall never forgive myself. I beg you to thank him, as I have done."

"It is so good of you," she said, sweetly, and held out her hand. "But I knew you would understand that it was just a great mistake."

"Mr. Paul Harley," Camber continued, "my wife welcomes you; and this, Ysola, is Inspector Aylesbury, who desires a few moments' conversation upon a rather painful matter."
