Roseman is Oedipa and Mucho’s lawyer, whom Oedipa briefly consults in the novel’s introductory chapter for advice about Pierce Inverarity’s will. Roseman is miserable because he obsessively compares himself to the television lawyer Perry Mason, and he flirts shamelessly with Oedipa until she points out that he is manipulating her in order to enjoy his own fantasy but does not actually mean any of the things he tells her.
