These artifacts marked the room as headquarters of the Whitechapel Club, named for the London slum in which two years earlier Jack the Ripper had done his killing. The club’s president held the official title of the Ripper; its members were mainly journalists, who brought to the club’s meetings stories of murder harvested from the city’s streets. The weapons on the wall had been used in actual homicides and were provided by Chicago policemen; the skulls by an alienist at a nearby lunatic asylum; the blanket by a member who had acquired it while covering a battle between the army and the Sioux.
