# Lady Mary Wimsey — Clouds of Witness character guide > Lady Mary Wimsey in Clouds of Witness by Dorothy L. Sayers. **Role:** major **Also known as:** Mary, Polly, poor old Mary, poor Lady Mary **First appearance:** 0002-clouds-of-witness ## Snapshot The Duke's headstrong sister, engaged to the murdered man, whose secret elopement plans and brittle composure make her both witness and suspect. ## Who they are Lady Mary arrives at Lord Peter's flat in a state of desperate agitation, her complexion strained and her eyes hollowed by recent illness, begging to see her brother before he does something dreadful. She is a young woman caught between an engagement she accepted out of weariness and a love she thought she had lost, and her frankness with Parker is as disarming as it is calculated. Her testimony — and her silences — sit at the center of the case against her brother, and her fragility is the human cost the investigation keeps threatening to expose. ## Relationships ### [Lord Peter Wimsey](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/lord_peter_wimsey) _family_ Siblings with a close, protective bond, with Peter often looking out for Mary during the murder crisis. ### [Captain Denis Cathcart](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/captain_denis_cathcart) _romantic_ Former fiancés, with a strained relationship ending in Cathcart's death and Mary's subsequent suspicion. ### [Mr. Goyles](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/mr_goyles) _romantic_ Secret romantic involvement, with Goyles as Mary's lover and a key figure in the murder mystery. ### [Viscount St. George](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/viscount_st_george) _family_ Siblings, with Mary and her brother Gerald (Viscount St. George) having a tense relationship due to the murder scandal. ### [Dowager Duchess of Denver](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/dowager_duchess_of_denver) _family_ Mother and daughter, with a caring but concerned dynamic due to Mary's involvement in the scandal. ### [Lord Peter Wimsey](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/lord_peter_wimsey) _family_ Siblings with a close, protective bond, with Peter often looking out for Mary during the murder crisis. ### [Lord Peter Wimsey](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/lord_peter_wimsey) _family_ Siblings with a close, protective bond, with Peter often looking out for Mary during the murder crisis. ### [Captain Denis Cathcart](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/captain_denis_cathcart) _romantic_ Former fiancés, with a strained relationship ending in Cathcart's death and Mary's subsequent suspicion. ### [Mr. Goyles](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/mr_goyles) _romantic_ Secret romantic involvement, with Goyles as Mary's lover and a key figure in the murder mystery. ### [Dowager Duchess of Denver](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/dowager_duchess_of_denver) _family_ Mother and daughter, with a caring but concerned dynamic due to Mary's involvement in the scandal. ### [Viscount St. George](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/viscount_st_george) _family_ Siblings, with Mary and her brother Gerald (Viscount St. George) having a tense relationship due to the murder scandal. ### [Captain Denis Cathcart](https://www.betterreads.dev/discover/clouds_of_witness_se/characters/captain_denis_cathcart) _romantic_ Former fiancés, with a strained relationship ending in Cathcart's death and Mary's subsequent suspicion. ## In the story ### [Clouds of Witness](https://www.betterreads.dev/discover/clouds_of_witness_se/chapters/clouds-of-witness) Sister of Lord Peter and the Duke, involved in the family's turmoil. ### [I: Of His Malice Aforethought](https://www.betterreads.dev/discover/clouds_of_witness_se/chapters/i-of-his-malice-aforethought) Sister of the Duke;
