“There is still one of which you never speak.”
Marco Polo bowed his head.
“Venice,” the Khan said.
Marco smiled. “What else do you believe I have been talking to you about?”
The emperor did not turn a hair. “And yet I have never heard you mention that name.”
And Polo said: “Every time I describe a city I am saying something about Venice.”
