232. On the island of Buiane, there are three villages: Pravdino, Kryvdino, and Seredina-na-Polovine. The residents of Pravdino are truth-lovers, the residents of Kryvdino are liars, and the residents of Seredina-na-Polovine are tricksters, but with a quirk: one of any two consecutive statements they make is true, and the other is false. Residents of each village can be found in the other two villages. One day, at the fire station on the island, where the duty officer was reading an engaging novel, the phone rang.

- Hurry up and come to us! There's a fire in our village! - he heard.
- In which village?
- In Seredina-na-Polovine, - was the answer.

What should the duty officer do - send the fire team and to which village?
$\triangle$ Let's consider three possibilities.

1) Suppose the caller was a truth-teller. But this contradicts the fact that the caller referred to his village as Middle-on-Half.
2) Suppose the caller was a liar. Then his statement "There is a fire in our village" is false.
3) Suppose the caller was a trickster. In this case, his last statement, which claims that he is from Middle-on-Half, is true. But then his previous statement "There is a fire in our village" is false.

It turns out that the duty officer should not send the fire brigade to any of the three villages.

Answer: continue reading the novel.
