Key passages

  • “You did,” she said in a hard voice. “I was too durned softhearted to do it a second time. I can’t tell you how I wish I had, though. You’ve led a poor kind of life for the last few years, Ruth.”

    Ruth bitterly acknowledges that her father once prevented her from doing something she wanted, and he regrets not being firmer, as her marriage has been miserable.

    Reveals past conflict between father and daughter and Van Aldin's regret over allowing the marriage.

  • “That’s why I say to you that this thing has got to stop !” He brought his hand down with a bang on the table. “You may have a hankering after the fellow still. Cut it out. Face facts. Derek Kettering married you for your money. That’s all there is to it. Get rid of him, Ruth.”

    Van Aldin insists the marriage must end, asserting that Derek only married Ruth for her fortune and urging her to divorce him.

    Highlights Van Aldin's blunt, decisive nature and his view of the marriage as purely mercenary.

  • “Heart of Fire,” like all famous stones, had left behind it a trail of tragedy and violence. Held in Ruth Kettering’s assured hand, it seemed to lose its potency of evil.

    The ruby necklace has a notorious history of causing misfortune, but Ruth's confident grip appears to neutralize its dangerous reputation.
