Without turning his head the wireless man continued to watch sharply the casual movements of this Chinese, quite as he had been observing him since they had left Tandjong Priok in the company's launch and come out to the Persian Gulf together.

He had suspected the fellow from the very first, and he was prepared, on the defensive; yet he was willing and eager to take the offensive should this son of the yellow empire so much as show the haft of his kris, or whisper a word of counsel in his ear. The latter he feared quite as much as the former, for it would mean many things.

As the fellow sidled a little closer, Peter was aware that the man was making queer signals with his slanting eyes for the purpose of attracting his attention, without arousing the curiosity or interest of any persons who might be observing the two.

Whereupon Peter turned on his left heel, walked to the other's side and gave him a stare of deliberate hostility.

The coolie moved backward a few inches by flexing his body; his feet remained as they were. And as Peter ran his eye from the black crown hat to the faded blue jacket, the black-sateen pants, which were clipped about the ankles, giving them a mild pantaloon effect, and to the black slippers with their thick buck-soles, the coolie smiled.

It was a smile of arrogance, of self-satisfaction. Indeed, it was the smile of a hunter who has winged his prey, and smiles an instant to watch it squirm before administering the death-shot.

"You wanchee my?" inquired Peter succinctly.

"You allatime go Hong Kong way?" replied the coolie, his smile becoming a little more civil, while he measured Peter's length, breadth, and seemed to estimate his brawn.

It was a foolish question, for the Persian Gulf, as everybody in Batavia knew quite well, made a no-stop run from the Javanese port to Hong Kong. Peter indicated this fact impatiently.

"No go Hong Kong way?" persisted the coolie, not relaxing that devilish grin. "Maskee Hong Kong. Nidzen yang gïang?"
