It was, instead of taking Stanton to the police station—where I would have been obliged to enter a specific charge against him—to take him to a secret place of confinement, and there keep him until I had bagged the river-pirates, penetrated to the Black Hole, and bursted up the villainous den.

To reach the place I had in my mind's eye, it was necessary to retrace some of our steps, and we once again entered the rough precincts right along the East River.

As Stanton had been treacherous to the force of which he was a member, was willing to be treacherous toward his pals, so, now, in keeping with his character, he acted treacherously toward me.

While passing a low drinking place—"boozing ken" was its popular name in that locality—he suddenly pursed up his lips and whistled sharply in a peculiar way, repeated a given number of times.

I knew he intended it for a signal.

I was not mistaken.

Within half a minute a little squad of men dashed out of the "boozing ken" to rescue him who had given this signal.
