In a city in France, a history teacher named Mitchell found a note in an old book. It said there was a large amount or treasure buried on an island near the city.
Mitchell invited his school's gym teacher Scott to go with to the island. They brought water, food, and Set out for the island. At first, they thought they would find the treasure and be back in a day or two. However, they got lost at sea and had no idea how to get back home.
They finished all of their food by the seventh day. I here was just half a bottle of water left. Scott kept it from Mitchell and wouldn't let him drink it.
"Please, give me some water," Mitchell begged. Hegrabbed atthe bottle and started fighting with Scott. In the end, Scott beat Mitchell to death.
Two days later, Scott was rescued (获救).He went onboard the rescue ship and took off his hat. His head was all wet with sweat.
Officer Derek watched Scott board the boat. He waited for Scott to tell his story. Scott later said that he killed Mitchell accidentally. He said he was trying to stop Mitchell from drinking seawater. By that time, they hadn't had any fresh water to drink for seven days.
"Are you sure that you hadn't had any water for seven days?" Derek said.
"Yes, it was all my fault. I was just trying to stop him from drinking the seawater," Scott answered.
"I see. That's quite interesting, Scott. I think you're lying. You killed him on purpose so you wouldn't have to share any fresh water with him."
How did Derek know that Scott was lying?
