In the offices of the Homicide Bureau of the Detective Division of the New York Police Department, on the third floor of the Police Headquarters building in Center Street, there is a large steel filing cabinet; and within it, among thousands of others of its kind, there reposes a small green index–card on which is typed: "ODELL, MARGARET. 184 West 71st Street. Sept. 10. Murder: Strangled about 11 p.m. Apartment ransacked. Jewelry stolen. Body found by Amy Gibson, maid."
Here, in a few commonplace words, is the bleak, unadorned statement of one of the most astonishing crimes in the police annals of this country—a crime so contradictory, so baffling, so ingenious, so unique, that for many days the best minds of the Police Department and the District Attorney's office were completely at a loss as to even a method of approach. Each line of investigation only tended to prove that Margaret Odell could not possibly have been murdered. And yet, huddled on the great silken davenport in her living–room lay the girl's strangled body, giving the lie to so grotesque a conclusion.
