# Motive vs. Psychology in Crime in The Benson Murder Case

> Theme guide for The Benson Murder Case by S. S. Van Dine.

Vance insists that motive is an irrelevant factor in solving crimes, as many people have similar motives; instead, he focuses on the unique psychological temperament of the murderer as the only reliable guide to guilt.

## Where it surfaces

- [Vance Accepts a Challenge](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/viii-vance-accepts-a-challenge): Vance contends that motive is irrelevant because everyone has motives; instead, individual psychology determines who acts on them.
- [A Motive and a Threat](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xi-a-motive-and-a-threat): The chapter explores Leacock's threat as a motive, but Vance's skepticism about Pfyfe's testimony suggests a deeper psychological complexity beyond surface motives.
- [The Grey Cadillac](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xiii-the-grey-cadillac): Vance probes the psychological profiles of suspects like Leacock and Pfyfe, exploring their temperaments and potential motives, rather than relying solely on physical evidence.
- [Links in the Chain](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xiv-links-in-the-chain): Vance argues that despite the logical evidence against Leacock, the psychological profile does not fit, highlighting the tension between motive and character.
- [Admissions and Suppressions](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xvi-admissions-and-suppressions): Vance contrasts conventional legal thinking with psychological insight, emphasizing the importance of understanding motives and personal relationships over mere evidence.
- [XVII: The Forged Check](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xvii-the-forged-check): Vance's psychological approach to extracting the truth from Mrs. Banning contrasts with conventional interrogation methods, emphasizing motive and psychology.
- [XVIII: A Confession](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xviii-a-confession): Vance challenges the surface motive of Leacock's confession, probing deeper psychological reasons such as chivalric self-sacrifice.
- [XIX: Vance Cross-Examines](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xix-vance-cross-examines): Vance argues that Leacock's psychological profile makes him capable of the crime but incapable of committing it in the manner it occurred, highlighting the distinction between motive and method.
- [XXI: Sartorial Revelations](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xxi-sartorial-revelations): Vance uses psychological deduction about Benson's behavior and the murderer's knowledge of the household to infer motive and identity.
- [XXIII: Checking an Alibi](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xxiii-checking-an-alibi): Vance argues the jewels were a mere addendum and that a deeper, vital motive drove the Major to murder, emphasizing psychological insight over surface evidence.
- [The Arrest](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xxiv-the-arrest): Vance emphasizes the Major's cold, calculating gambler psychology as key to understanding the crime, rather than mere motive.
- [XXV: Vance Explains His Methods](https://www.betterreads.dev/discover/the_benson_murder_case_se/chapters/xxv-vance-explains-his-methods): Vance emphasizes that the method of the crime (bold, direct, premeditated) was a direct expression of the Major's psychology, not merely his motive.
