# XXIII: Checking an Alibi explained — The Benson Murder Case

> Chapter companion for The Benson Murder Case by S. S. Van Dine.

## What happens

Vance and Markham visit Major Benson's apartment to investigate his alibi for the night of the murder. Through questioning the elevator boy, Vance establishes that the Major returned home around 11 p.m., gave the boy a large tip, and later requested cracked ice, asking the time to set his watch. The boy confirms the Major did not leave again. Despite the alibi, Vance remains convinced of the Major's guilt, arguing the motive was not the jewels but something deeper. He searches the apartment and finds a locked humidor containing a blue-velvet jewel-case, which he forces open, revealing the stolen jewels. Markham is devastated by the discovery.

## Key lines

> Why should you gag at the Major, who actu’lly is guilty?

Vance chides Markham for hesitating to accept the Major's guilt after readily suspecting innocent people.

_Vance's contemptuous tone contrasts with an inscrutable look, revealing his underlying sympathy for Markham's struggle._

> The jewels were a mere addendum. There was a vital motive—rest assured.

Vance insists the motive for murder was not the jewels themselves but something more significant.

_This reflects Vance's psychological approach, looking beyond surface evidence to deeper motivations._

> He’s forthright in all his mental operations. Like Poe’s Minister D—, he would recognize the futility of painstakingly secreting the jewels in some obscure corner.

Vance compares the Major to a character from Poe, suggesting he would hide the jewels in a simple, locked container rather than an elaborate hiding place.

_Vance uses literary analogy to deduce the location of the stolen jewels._
