The Benson Murder Case · Chapter
X: Eliminating a Suspect explained
Vance interrogates the housekeeper, Mrs.
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.
