The man glanced at her and said:

“I know what I am about, Sally.”

Carter knew from this that the woman was Rich’s sister. The other woman he surmised was Isabella Porter.

A broad grin spread over the cabby’s face.

“Yes, be careful, Mr. Rich,” he sneered. He was becoming more insolent the longer he waited.

Rich wheeled around. His large, black eyes were flashing, his face was aflame with passion.

You be careful,” he hissed between his clenched, white teeth, and he drew his arm back.

Sally threw herself between her brother and the cabman.

“Sim,” she ejaculated, “calm yourself.”
