The chance discovery of an old letter buried in Yale University's archives for nearly a century threatens to expose a heinous crime allegedly committed by members of Skull and Bones, America's most powerful secret society.

At New York City's The Intrepid Sea, Air, & Space Museum these are 4 mysterious objects. At first glance, they look like mere mechanical debris, but these are actually the remains of one of the most dreaded weapons of World War Two.
