He missed, but nothing daunted, the sailor started in pursuit, calling out in a husky voice at every step. In his eagerness to catch up with Willis Round, Nattie had continued his flight. The hubbub and outcry behind him soon brought him to a halt, and he faced about just as several policemen and a dozen foreigners and native citizens joined in the chase.

What the outcome would have been is hard to say had not help arrived at that opportune moment in the shape of a friend—a clerk at the legation—who suddenly appeared in the doorway of a private residence within a dozen feet of the lad.

"What is the matter, Manning?" hastily asked the newcomer.

As quick as a flash Nattie bounded past him, and closed the door just as the infuriated sailor reached the spot.

"For goodness' sake, old fellow, get me out by the back way!" breathed the lad. "I haven't time to explain now. I'll tell you all about it this afternoon. I am following a man, and I mustn't lose him. Let me out by the rear, please."

Considerably mystified, the clerk obeyed. A moment later Nattie was again speeding down a street toward the Bund. As luck would have it, he caught sight of his man at the next corner. The jinrikisha had stopped in front of Black & Company's office.

Hurrying ahead, the lad contrived to enter the door at the heels of the fugitive. He stepped lightly across the counting-room, and was within a foot of him when he threw open the door leading into the merchant's private office.

At sight of them both Ralph and his father sprang to their feet. Totally unsuspicious of the proximity of his pursuer, the tall, thin man tossed his portmanteau upon a chair, and was on the point of greeting the occupants of the office when he saw them looking behind him in evident surprise.

He turned, gave Nattie one startled glance, then made an involuntary movement as if contemplating flight. The lad barred the way, however. Grinning triumphantly, he lifted his hat with a polite bow, and said:

"Why, this is an unexpected pleasure, Mr. Round. I did not know you had returned to Yokohama. How is everything in London?"
