"Much obliged, sir," he said. "Yes—the fact is, Mr. Yada, I called to see you on a highly important matter that's arisen. Your name, sir, was given to me tonight by one of the junior house-surgeons at the hospital up the street—Dr. Pittery."
"Oh, yes, Dr. Pittery—I know," agreed Yada. "Yes?"
"Dr. Pittery tells me, sir," continued Ayscough, "that you know two
Chinese gentlemen who are fellow-students of yours at the hospital, Mr.
Yada?"
The Japanese bowed his dark head and blew out a mouthful of smoke from his cigar.
"Yes!" he answered readily, "Mr. Chang Li—Mr. Chen Li. Oh, yes!"
"I want to ask you a question, Mr. Yada," said Ayscough, bending forward and assuming an air of confidence. "When did you see those two gentlemen last—either of them?"
Yada leaned back in his comfortably padded chair and cast his quick eyes towards the ceiling. Suddenly he jumped to his feet.
"You take a little drop of whisky-and-soda?" he said hospitably, pushing a clean glass towards Ayscough. "Yes—I will get another glass for your friend, too. Help yourselves, please, then—I will look in my diary for an answer to your question. You excuse me, one moment."
He walked across the room to a writing cabinet which stood in one corner, and took up a small book that lay on the blotting-pad; while he turned over its pages, Ayscough, helping himself and Melky to a drink, winked at his companion with a meaning expression.
"I have not seen either Mr. Chang Li or Mr. Chen Li since the morning of the 18th November," suddenly said Yada. He threw the book back on the desk, and coming to the hearthrug, took up a position with his back to the fire and his hands in the pockets of his trousers. He nodded politely as his visitors raised their glasses to him. "Is anything the matter, Mr. Detective-Sergeant?" he asked.
