Rumor has it that there is a spy on the ship. The captain suspects three sailors;
Tom, 45 years old:
"I'm definetely not a spy. I've been working here for 15 years."
Henry, 24 years old:
"I can't be a spy. I'm too weak and I don't even know how to swim."
Kit, 18 years old:
"I started working here just two moths ago. I'm not a spy I swear!"After hearing this, the captain detected the spy.
Who is the SPY???
