It was a long ride, and not until after night had fallen and reigned supreme did the detective enter the capital of the western province.
The streets of Perth were dark enough, but he heard the sounds of revel which emanated from more than one den of sin and crime, but he kept on.
Suddenly he was startled to discover that he was followed, that a silent figure crept after him on the narrow sidewalk.
Old Broadbrim watched the shadower for some time and came to the conclusion that he was really watched.
In front of the main hotel he dismounted and turned to the door.
The spy had stopped and stood over against the building across the street statue-like in his pose and keen-eyed.
Belle Demona had a spy in Perth!
Old Broadbrim entered the hotel and had Black Duke cared for.
All at once as he turned a corner he came face to face with a man who started back.
There was something familiar in the shape, and the next moment the detective seized the arm before him.
