Van Dine. **Role:** major **Also known as:** Vance, Mr. Vance, Van, Van Dine, Mr. Van Dine **First appearance:** 0003-the-greene-murder-case ## Snapshot A debonair amateur criminologist whose cynical wit and uncanny readings of character make him the District Attorney's secret weapon on the Greene case. ## Who they are Vance drifts into the Greene investigation by pure coincidence, tagging along with his old friend Markham and treating murder as an aesthetic puzzle rather than a civic duty. His Juvenalian irony and aristocratic detachment clash with Markham's grim legal conscience, yet the two men are bound by a friendship each secretly envies in the other. His habit of dissecting motives the way he dissects art turns the family's genteel surface into a map of hidden pressures, making him the reader's best guide through the mansion's mounting unease. ## Relationships ### [Ernest Heath](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/ernest_heath) _professional_ Heath, as a police officer, works alongside Vance on the case, often with grudging respect but professional tension. ### [Chester Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/chester_greene) _rivalry_ Chester is hostile and antagonistic toward Vance, viewing him as an intrusive outsider in the Greene family affairs. ### [Sibella Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/sibella_greene) _psychological_ Vance is fascinated by Sibella's manipulative and enigmatic nature, analyzing her as a key figure in the case. ### [Doctor Von Blon](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/doctor_von_blon) _professional_ Von Blon cooperates with Vance as the family physician, providing medical insights while maintaining a cautious distance. ### [Ada Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/ada_greene) _friendship_ Ada trusts and confides in Vance, seeing him as a protector and ally amid the family turmoil. ### [Chester Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/chester_greene) _rivalry_ Chester is hostile and antagonistic toward Vance, viewing him as an intrusive outsider in the Greene family affairs. ### [Ada Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/ada_greene) _friendship_ Ada trusts and confides in Vance, seeing him as a protector and ally amid the family turmoil. ### [Ernest Heath](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/ernest_heath) _professional_ Heath, as a police officer, works alongside Vance on the case, often with grudging respect but professional tension. ### [Doctor Von Blon](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/doctor_von_blon) _professional_ Von Blon cooperates with Vance as the family physician, providing medical insights while maintaining a cautious distance. ### [Sibella Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/sibella_greene) _psychological_ Vance is fascinated by Sibella's manipulative and enigmatic nature, analyzing her as a key figure in the case. ### [Ernest Heath](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/ernest_heath) _professional_ Heath, as a police officer, works alongside Vance on the case, often with grudging respect but professional tension. ### [Sibella Greene](https://www.betterreads.dev/discover/the_greene_murder_case_se/characters/sibella_greene) _psychological_ Vance is fascinated by Sibella's manipulative and enigmatic nature, analyzing her as a key figure in the case. ## In the story ### [Characters of the Book](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/characters-of-the-book) The central detective figure. ### [The Greene Murder Case](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/the-greene-murder-case) Joins the investigation as a key figure. ### [I: A Double Tragedy](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/i-a-double-tragedy) Present at Markham's office; expresses skepticism about the burglary theory and decides to stay for Chester Greene's visit. ### [The Investigation Opens](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/ii-the-investigation-opens) Accompanies Markham and interrogates Chester Greene, noting key details such as the lights being on in both rooms and the differing angles of the shots, which hint at a non-burglar motive. ### [At the Greene Mansion](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/iii-at-the-greene-mansion) Observes details, times Chester's reenactment, and asks about Julia's locked door. ### [IV: The Missing Revolver](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/iv-the-missing-revolver) Takes command of the interviews, using indirect questioning to assess the household's dynamics and the servants' characters. ### [V: Homicidal Possibilities](https://www.betterreads.dev/discover/the_greene_murder_case_se/chapters/v-homicidal-possibilities) Vance leads the questioning of Sibella, probing her skepticism about the burglar theory and her knowledge of the missing revolver.
