They say the song of a siren could easily lead a man to his death. And that was true. Their voice is deadly yet beautiful. Because of this, you would normally use it to your advantage.
However, this one time...it didn't work.
You were swimming around as normal, the water was luke warm and the moon reflecting on the water was lovely. You popped up from the water due to you hearing a noise. A boat! A boat was in the distance with a man in it. You smirked at the sight and hummed to try lure the man. Yet, there was nothing. So you swam closer and tried again. Nothing. So, you decided to go right up to the boat and investment the man, from behind of course so you didn't get caught.
Although just as you were about to go back in the water. He spoke.
"I know your there" He explained in a deep voice, followed by a chuckle. You froze.
