"Do I know Dr. Ichi?" echoed the boatswain. "Do I know——"

He glowered at Martin. The query seemed to inflame his temper.

"Do you know Ichi? Hey? Say, do you know Ichi? That's what I want to know!" His manner became threatening. "Why, swiggle me stiff, you must be one o' them, yourself!"

Assault seemed imminent. Martin backed hurriedly away.

"No, no, you are quite mistaken," he assured the boatswain. "You may be sure I am not one of them, whoever they are. I am your friend."

The boatswain subsided growlingly. He was plainly suspicious—of what, Martin could not guess. But it was evident that any mention of the name of Ichi peppered his temper.

If Martin had been a cautious young man he would have let well enough alone. The boatswain seemed a hasty and a heavy-fisted man. But Martin's interest was more than piqued. Here seemed a chance to learn something about that mysterious Japanese. This sailor appeared to know him. Some light might even be thrown upon his errand to the Black Cruiser. The papers in his inside pocket oppressed him with their secret.

"Perhaps Little Billy is down on the waterfront," he remarked casually. "He mentioned to me that he was going to look up a friend on the Embarcadero—a fellow named Carew. Do you know Captain Carew? At a place called the Black Cruiser?"

The boatswain received the remark in a most disconcerting manner. He stiffened and stared at Martin, mouth agape, for an appreciable instant. He seemed breathless. The semi-paralysis of drunkenness seemed to flee his face.

"Carew! Did you say Carew?" he at last exclaimed. "Strike me, 'e says Carew!"
