Psychological Detection vs. Conventional Policing
Vance argues that psychology and temperament are the only reliable means of detection, contrasting with Markham's reliance on motive, opportunity, and legal logic.

Key passages
“fully as much in their manner, their aspects, and their general nature, as do works of art. Indeed, a carefully planned crime is just as direct an expression of the individual as is a painting, for instance. And therein lies the one great possibility of detection.”
Vance compares a planned crime to a work of art, arguing that both reveal the creator's personality, making psychological analysis the key to detection.
Vance introduces his core theory that crime is an expression of individual psychology.
“Your system ignores motive altogether, he objected. Naturally, Vance replied, since it's an irrelevant factor in most crimes.”
Markham criticizes Vance for dismissing motive, but Vance insists motive is irrelevant because everyone has motives.
Vance dismisses motive as a universal and therefore useless factor in solving crimes.
“I'm going to accept your challenge. It's a bit alien to my tastes; but the problem, y' know, rather appeals to me: it presents the same difficulties as the Concert Champêtre affair—a question of disputed authorship, as it were.”
Vance agrees to Markham's challenge, likening the murder case to an art attribution problem.
Vance formally accepts the challenge, framing the investigation as an intellectual puzzle.
“First, he announced, I shall determine the exact height of the guilty person. Such a fact will, no doubt, come under the head of indicat'ry evidence—eh, what?”
Vance declares he will deduce the murderer's height, mocking conventional evidence.
Vance's first step is to determine the height of the killer, using his psychological methods.
