That was all. Where he had gone or when he would return Keith could not discover from Li King. Of all other matters except that he had gone away the manager of Shan Tung's affairs was ignorant. Keith felt like taking the yellow-skinned hypocrite by the throat and choking something out of him, but he realized that Li King was studying and watching him, and that he would report to Shan Tung every expression that had passed over his face. So he looked at his watch, bought a cigar at the glass case near the cash register, and departed with a cheerful nod, saying that he would call again.

Ten minutes later he determined on a bold stroke. There was no time for indecision or compromise. He must find Shan Tung and find him quickly. And he believed that Miriam Kirkstone could give him a pretty good tip as to his whereabouts. He steeled himself to the demand he was about to make as he strode up to the house on the hill. He was disappointed again. Miss Kirkstone was not at home. If she was, she did not answer to his knocking and bell ringing.

He went to the depot. No one he questioned had seen Shan Tung at the west-bound train, the only train that had gone out that morning, and the agent emphatically disclaimed selling him a ticket. Therefore he had not gone far. Suspicion leaped red in Keith's brain. His imagination pictured Shan Tung at that moment with Miriam Kirkstone, and at the thought his disgust went out against them both. In this humor he returned to McDowell's office. He stood before his chief, leaning toward him over the desk table. This time he was the inquisitor.

"Plainly speaking, this liaison is their business," he declared. "Because he is yellow and she is white doesn't make it ours. I've just had a hunch. And I believe in following hunches, especially when one hits you good and hard, and this one has given me a jolt that means something. Where is that big fat brother of hers?"

McDowell hesitated. "It isn't a liaison," he temporized. "It's one-sided—a crime against—"

"WHERE IS THAT BIG FAT BROTHER?" With each word Keith emphasized his demand with a thud of his fist on the table. "WHERE IS HE?"

McDowell was deeply perturbed. Keith could see it and waited.

After a moment of silence the iron man rose from the swivel chair, walked to the window, gazed out for another moment, and walked back again, twisting one of his big gray mustaches in a way that betrayed the stress of his emotion. "Confound it, Conniston, you've got a mind for seeking out the trivialities, and little things are sometimes the most embarrassing."

"And sometimes most important," added Keith. "For instance, it strikes me as mighty important that we should know where Peter Kirkstone is and why he is not here fighting for his sister's salvation. Where is he?"

"I don't know. He disappeared from town a month ago. Miriam says he is somewhere in British Columbia looking over some old mining properties. She doesn't know just where."
