Holmes swirled the red wine around his glass. "The way this gentleman holds the knife shows that he has had medical training, yet, he has the bearing of a soldier. So, it is clear that he was a military doctor. His face is dark, yet the rest of him fair—so he must have spent a good amount of time in the tropics. His complexion is poor, his face haggard, and he has obviously been wounded on his left arm because it looks a little stiff. So, the question is, where in the tropics can a military doctor get wounded? Clearly, only in Afghanistan."

"Don't be so quick to give up," encouraged Holmes. "If you win, I will show you my collection of newspaper clippings. You can always come to me if there's anything you don't understand."

"Really?" Zhang Heng's eyebrows rose in intrigue.
