Alexandre Quartermaine and Professor Maximillion Avery investigate a hidden lair of the Brotherhood of Darkness beneath the Statue of Liberty. While they search the tomb-chest full of gold and a strange dagger, the Brotherhood’s leader Sonatine arrives. He forces Quartermaine to hand over the dagger, then instead takes a lost manuscript by Miguel de Cervantes and tells her he will read it—and then kill her. Meanwhile, Cervantes and his sidekick Sancho Panza are hiding in a barn occupied by the gypsy Michaelangelo Estacado, who is laying low after an affair with a maid.
