An absorbing show but painful, both because of the grisly subject matter (the 1977 rape-murders of ten young women in Southern California) and because of the controversial role played by Dr. Watkins in the investigation and trial, and the merciless interrogation of him here by Mr. O'Brien on the question whether one of the Stranglers had a multiple personality. Mr. O'Brien: "Later on, [Kenneth] Bianchi was able to confess in great detail, which could be corroborated by outside evidence, to all the murders in his personality as Ken without ever bringing in this 'Steve' business. Nor had 'Steve' ever been seen before you [Dr. Watkins] talked to him, nor has he ever come out afterwards."
