At the cold, steely look in his eyes the mermaid shivered a little, but tried to appear unperturbed. She still had to try, to come up with something believable so that she could have a chance to escape.
"I think there is something...but I don't recall exactly where though." she stated slowly, trying her best to meet his gaze and not look like she was fibbing. "It's in an underwater cave though, so I don't know if you could get to it. Some say if you find the right signs it will point out the way quite clearly. I could tell you the signs if you promise to let me go after." Turquoise pleaded hopefully.
"In this cave, you'll find a treasure so beautiful and exquisite, enough to make a living from for the rest of one's life! And probably longer too." the mermaid continued her extravagant tale, hoping the captain would buy it. "As to what the treasure is, well, I'll let you discover that yourself when you find it. Much more valuable than me many times over!" Turquoise finished and looked expectantly up at the pirate captain, trying to gauge his reaction.
