# Bertram Cody — The Door with Seven Locks character guide > Bertram Cody in The Door with Seven Locks by Edgar Wallace. **Role:** supporting **Also known as:** Mr. Bertram Cody, Mr. Cody, Bertie, Cody, Elbert, Bertram, Dr. Cody **First appearance:** 0002-i ## Snapshot An oily, evasive man who denies any contact with the strange Lord Selford while quietly carrying a leather purse holding a key that mirrors Sybil Lansdown's own. ## Who they are Dick Martin visits Cody on business and leaves with more than he bargained for, having palmed the flat leather book from under the man's papers out of sheer devilment. Inside is a key almost identical to the one Sybil showed him on the train — the same key that unknown men have already gone to violent expense to recover. Cody's flat denial of any link to Lord Selford, set against the evidence in Dick's pocket, makes him the hinge on which the mystery of the seven locks first swings open. ## Relationships ### [Sybil Lansdown](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/sybil_lansdown) _family_ Bertram Cody is Sybil Lansdown's father, with a protective but possibly strained relationship. ### [Dick Martin](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/dick_martin) _professional_ Bertram Cody interacts with Dick Martin as a concerned parent and potential ally in the investigation. ### [Thomas Cawler](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/thomas_cawler) _professional_ Bertram Cody and Thomas Cawler have a business or servant relationship, possibly involving secrets. ### [Dick Martin](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/dick_martin) _professional_ Bertram Cody interacts with Dick Martin as a concerned parent and potential ally in the investigation. ### [Sybil Lansdown](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/sybil_lansdown) _family_ Bertram Cody is Sybil Lansdown's father, with a protective but possibly strained relationship. ### [Thomas Cawler](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/thomas_cawler) _professional_ Bertram Cody and Thomas Cawler have a business or servant relationship, possibly involving secrets. ### [Sybil Lansdown](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/sybil_lansdown) _family_ Bertram Cody is Sybil Lansdown's father, with a protective but possibly strained relationship. ### [Thomas Cawler](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/thomas_cawler) _professional_ Bertram Cody and Thomas Cawler have a business or servant relationship, possibly involving secrets. ### [Dick Martin](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/characters/dick_martin) _professional_ Bertram Cody interacts with Dick Martin as a concerned parent and potential ally in the investigation. ## In the story ### [VII](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/chapters/vii) Linked to Pierce via blotting-paper impression found in Buenos Aires. ### [VIII](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/chapters/viii) Receives the visitor under the alias John Rendle, reveals his knowledge of the gold discovery, and later panics upon discovering the theft of his notebook and key. ### [IX](https://www.betterreads.dev/discover/the_door_with_seven_locks_se/chapters/ix) Visited by Dick;
