Black Market Vendor Perhaps?

I started walking towards one of the many vendors, but was suddenly grabbed and pulled into a nearby alley. "What ..." "Keep quiet," a deep voice said. I turned and saw a short man wearing a hooded cloak. "You're new here, huh? And looking for something to buy?" "You have something to sell?" Part of me thought that this was a bad idea, that I should buy from one of the regular vendors, but the secrecy of this guy intrigued me. Perhaps he had something that the vendors didn't. I might even get a good deal. Beneath the hood, I could see the man grin. "Oh yes. I definitely do."
