In the Season 3 premiere, Belle's book is a success but she worries about having enough material for a follow-up tome. Belle's sister Jackie shows up on her doorstep needing a place to stay after leaving her unfaithful husband.

In the Season 3 finale, the secret tryst between Duncan and Bambi is revealed at the latter's wedding, leaving Belle heartbroken but providing fodder for her new book's final chapter. Ben reveals his true feelings at the eleventh hour.

Belle tries to broaden Jackie's sexual horizons by taking her to a fetish club, with surprising results. Blocked in trying to write another book, Belle seeks support from her editor, Duncan.

Belle investigates the other side of the bed by hiring a male escort and experiencing the client point of view, but feels guilty about "cheating" on Duncan - whom she does not realize employed Bambi's services earlier in the evening.

The sexual attraction between Belle and Duncan heats up over a late-night chat session, while Jackie wants her sister to accept that she and Ben are now a couple, and Bambi ignores Belle's warnings and falls for a handsome client.

Belle provides sage counsel to Ben regarding his failing relationship with Jackie, and to Bambi over her romance with her client, Byron - but she promptly ignores her own rules with Duncan.

Belle resists the notion of a serious relationship with Duncan until Bambi announces that she and former client Byron have become engaged.

The first meeting of Duncan and Ben does not go well, leaving Belle facing a dilemma: which man should she choose to keep in her life?
