Bobby loved Graydon Bansemer in the way that one man loves a true friend. He was certain that the son knew nothing of those shady transactions--if they really existed as Harbert painted them--but an exposure of the father would be a blow from which he could not recover.
It came at last to Rigby that he was not the only one in Chicago who held the secret. Other members of the bar had been warned long before the news came to him, and it was morally certain that if the facts were as bad as intimated, the police also were in possession of them.
At the same time, Rigby felt a certain moral responsibility involving himself. Bansemer, at any time, might apply his methods to people who were near and dear to him. The new intimacy with the Cables came to Bobby's mind. And then, there were Clegg, Groll, the Semesons and others who might easily fall into the snare if James Bansemer set it for them.
Appreciating his responsibility in the matter, now that he was prepared to hear the worst of James Bansemer, Rigby's heart stood almost still. It meant that some day he might have to expose Graydon Bansemer's father; it meant that he might have to cruelly hurt his friend; it meant that he might lose a friendship that had been one of his best treasures since the good, old college days. The mere fact that he would be compelled to watch and mistrust James Bansemer seemed like darkest treachery to Graydon, even though the son should not become aware of the situation. Later, in the afternoon, Bobby went, guiltily, into a telegraph office and sent away a carefully worded dispatch. The answer came to him at the club, that evening, while he played billiards with young Bansemer, who, even then was eager to be off to keep the promised appointment with pretty Miss Cable.
The telegram which he opened while Graydon impatiently chalked his cue and waited for him to play was brief and convincing. It read: "Watch him, by all means. He is not safe, my word for it. There is no mistake."
