How does Cool Breeze say things started to go downhill for Ida?

Things go downhill after Ida starts working for Harpo Delahoussey. On one occasion, Cool Breeze catches Ida snorting cocaine and later he learns that Ida is prostituting herself for money to a predominantly white clientele. At one point, Ida writes Cool Breeze a letter, informing him that she is having an affair with Alex Guidry.
