“Telephone Ringing in the Labyrinth” is one of Adrienne Rich’s most unpredictable and evocative collections. In the folk/blues tradition behind “Rhyme,” in the incantatory pattern of “Behind the Motel,” in the voices from past and present in “Letters Censored, Shredded, Returned to Sender or Judged Unfit to Send,” in the dystopic scenes and intimate encounters of “Draft # 2006,” in the mysterious negotiations of the title poem, the tempos and moods of this book constantly vary. Here, Rich draws on the artistic means of a lifetime.
