Who is Beverly Axlerod from Soul on Ice and what is their importance?

Axlerod is a San Francisco attorney who first met Cleaver for advice on legal matters while he was housed in Folsom Prison. In September 1965, the two began communicating on a personal level and expressed their desire for a long-term relationship together. Cleaver first mentions that he's attracted to an attorney without mentioning her name. He expresses that he's incredibly taken with her, but the reader doesn't get details until the letters between the two.
