Lady Helen is Inspector Lynley's primary love interest. Helen once refused to marry Lynley and this put a strain on their relationship. Helen feels as though marrying Lynley would mean giving up her inner self and she is not willing to do this. What Helen fears most is becoming like her sister, Pen where she is saddled with children without a fulfilling career, catering to her husband's every whim. Eventually, however, Helen and Lynley resume their romantic relationship after the Elena Weaver case is put to rest.
