30. Who Killed Benjamin Nathan?

Benjamin Nathan, a wealthy stockbroker and philanthropist, was found brutally beaten to death in his home the morning of July 29, 1870. Some jewelry and a small amount of cash were stolen and the police were quick to rule the incident a burglary gone bad. But if so, how and when did the burglars enter? And how could four others staying in the house sleep through the violent attack? In fact, the Nathan murder looked more like a classic “locked-room” mystery—a mystery that remains unsolved.
