It's about as believable as the rest of the characters. Clean up after yourself. Time and again the incredibly powerful conspiracy of bad rich dudes fools Toni into participating in illegal activity, brings the police force down on her, and then drops a big crack vial or videotape of a professor in flagrante delicto in front of her so that she doesn't lose interest. The reader is forced to conclude that an entire mob of Harvard-educated businessmen and trustees really has no concept of the importance of evidence in conducting an investigation. Perhaps they failed to consult their law firm.
People ought to earn their place.
Yet these specimens of mental inferiority still keep showing up at party after party, leaving our heroine with no choice but to leave in disgust and immediately find a soft-core scene to wander into.

The sad truth is that the events of the novel are purely fictional, based on a scandal that broke at Brown University in 1986.
