A Merchant from the King's City (Part II)

"Do you primarily sell saltpeter in the king's city?" Roland came straight to the point.

"No, Your Highness." The smile on Margaret's face was no longer a fake one of formality but became more sincere and cordial. "I sell many products, from gemstones to fabrics, and I also run inns and taverns. In fact, I just started selling saltpeter a month ago. The previous business owner lost everything in my casino and had to put a lien on his plant."

[She not only sells various goods but also involves in the service industry. What kind of businesswoman is she?] Roland knew it required more than capitals to operate a casino in the king's city. He knocked on the desk, but Nightingale simply pinched his neck, which meant Margaret was wearing a God's Stone of Retaliation that blocked her scrutiny.

Hang on... If Nightingale can't detect lies, why did she pinch his right shoulder earlier?

Roland coughed and suppressed the desire to turn around and question her.
