Dr. Roberts was a practicing psychiatrist who assisted William Murdoch with a number of cases.
Roberts helped Murdoch diagnose multiple personality disorder in the case of Charlotte, who was suspected of having murdered her father.
Roberts was called up by Murdoch again to put him in a state of hypnosis as he played a recording of a mysterious person from a talking doll, which was part of a mystery involving a kidnapped-later-rescued girl, and a decapitated corpse. Murdoch soon recognized the voice to be belonging to James Gillies
