Paris, 1938. A shadow edges over Europe. Democratic forces are locked in struggle, while in Spain the war has already begun.

Cristian Ferrar, a handsome Spanish lawyer in Paris, is a well-connected man. Ferrar is approached to help a clandestine agency supply weapons to beleaguered Republican forces and agrees, putting his life on the line.

Joining Ferrar in his mission is an unlikely group of allies; idealists and gangsters, arms traders and aristocrats, including Max de Lyon, a man hunted by the Gestapo, and the Marquesa Maria Cristina, a refined beauty with a taste for danger.

From libertine nightclubs in the City of Light to volatile bars by the docks in Gdansk, Furst paints a spell-binding portrait of a continent marching into a nightmare - and the heroes and heroines who fought back.
