In a city in France, a history teacher named Mitchell found a note in an old book. It said there was a large amount of tburied (埋) on an island near the city.
Dreaming of being the richest man in the city, Mitchell decided to do something. He invited his school's gym teacher Scott to go with him to the island. They brought w, food, and set out for the island. At first, they thought they would find what they want and be back in a day or two. And start the life of the richest in the city. However, they got l at sea and had no idea how to get back home.
They f all of their food by the seventh day. There was just half a bottle of water l. Scott kept it from Mitchell and wouldn't let him drink it. They fought. In the end, Scott beat Mitchell heavily and Mitchell d.
Two days later, Scott was rescued(获救). On the rescue ship, he took off his hat and his head was sweaty(汗津津的). Officer Derek waited for Scott to tell his story. Scott said that he k Mitchell by accident. He said he was trying to s Mitchell from drinking seawater. By that time, they hadn't had any water to drink for seven days.
"I see. That's quite interesting, Scott. I think you're l. You killed him on purpose so you wouldn't have to s any fresh water with him."
How did Derek know that Scott wasn't telling the truth?
