The Just Men of Cordova [EPUB ebook] 

The man who sat at the marble-topped table of the Café of the Great Captain—if I translate the sign aright—was a man of leisure. A tall man, with a trim beard and grave grey eyes that searched the street absently as though not quite certain of his quest. He sipped a coffee con leche and drummed a little tune on the table with his slender white hands.

He was dressed in black, which is the conventional garb in Spain, and his black cloak was lined with velvet. His cravat was of black satin, and his well-fitting trousers were strapped under his pointed boots, in the manner affected by certain caballero.
