Baroness Emmuska Orczy 
Eldorado [EPUB ebook] 

Armand St Just, his beautiful sister Marguerite and her husband Sir Percy Blakeney are once again caught up in the turmoil of revolutionary France. And adventurer Baron de Batz enters the story. It is 1794 and Paris, “despite the horrors that had stained her walls – had remained a city of pleasure, and the knife of the guillotine did scarce descend more often than did the drop-scenes on the stage.”
