Here, in Chinatown, Cleve was in the enemy’s territory. He knew well that Ling Soo would know of his presence. Being aware of it, Ling Soo would be sure to have his henchmen on the trail.

That was what Cleve wanted. For he had an uncanny ability when it came to spotting hidden watchers. He had proven this tonight, when he had seen that shadow. Only a shadow — but a shadow meant a man in the background.

Cleve was thoughtful as he again wended his way along a slanting thoroughfare of Chinatown. His regular formula called for a new step now. It was time to turn the tables on those who were watching him — to watch them instead.

Ordinarily, Cleve would have waited longer, in hopes of gaining a complete knowledge of unknown watchers. But here, in Chinatown, the streets seemed peopled with unseen eyes. Latticed windows were suspicious. Alleyways seemed made for lurkers. Even the smiling shopkeepers must be taken into consideration.

So Cleve decided to lose no time. He would investigate the Wu-Fan; and before he began, he would gain the additional information he required, from one qualified to know.

TURNING into a side street, as though at random, Cleve Branch strolled by a little restaurant. He gazed curiously at the sign above the doorway. There, surrounded by Chinese characters, he read the words:

HOANG-HO CAFE.

The place seemed picturesque. Cleve entered. He ascended a flight of stairs, and found himself in a little room that had entrances in each of its four walls. Patrons could enter it from all quarters.

Cleve glanced at the menu. He chose an item that suited his taste. When a waiter approached, Cleve indicated his choice, with the point of a lead pencil that he had taken from his pocket.

Beneath the printed item, Cleve carelessly traced a little wavy line. The waiter bowed and left to get the order.
