# X: Eliminating a Suspect explained — The Benson Murder Case

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

## What happens

Vance interrogates the housekeeper, Mrs. Platz, about a young lady who visited Alvin Benson on the afternoon of his murder. Despite her initial denials, Vance uses psychological pressure and material clues to extract the truth: Muriel St. Clair called that afternoon, had tea, and left before Benson went to dress. Vance then explains to Markham how he deduced these facts from cigarette butts, the condition of the samovar, and the position of the chair, while also revealing that the murderer was tall and that no woman committed the crime.

_Vance uses a mix of reassurance and threat to pressure the housekeeper into confessing._

> I didn't; but I surmised it. There were cigarette butts of hers in the grate; and, as I knew she hadn't been here on the night Benson was shot, I thought it rather likely she had been here earlier in the day.

Vance explains that he deduced Muriel St. Clair's afternoon visit from cigarette butts and the timing of the murder.

_Vance reveals his deductive reasoning based on material evidence._

> The psychological aspects of the crime left me in no doubt. As I told you, no woman committed it—my metaphysical hypotheses again; but never mind.

_Vance relies on his psychological theories to eliminate Muriel St. Clair as a suspect._
