New York dilettante Philo Vance decides to assist the police in investigating the death of another man-about-town because he finds the psychological aspects of the crime of interest, and feels that they would be beyond the capacities of the police, even those of his friend District Attorney Markham. Together, Vance and Markham investigate Benson's business associates and romantic interests, and Vance investigates the circumstances under which the body was found, trying to reconstruct the crime.
