THE FORGOTTEN STEP (1938)

An American art collector, living in France in the 1870s, who loses his fortune in a stock market crash devises a scheme to get back his wealth through insurance fraud with the added consequence of potentially killing hundreds of people. His scheme is to place his art collection aboard a ship, insure the collection far beyond its value, and place a barrel of dynamite with a clock-piece timed to go off when the ship is at sea.
