7. Now, I suggest you try yourself in this intriguing riddle. One beautiful summer day a detective and his partner were chasing a criminal. When they went thru the forest they came to a shore of a very deep and rough river. The detective came to the only group of people that was on the shore and said that he is looking for a man of their age that went this way.


Young people said that they saw a suspicious man passing by a few minutes ago. They said he jumped into the river, crossed it and in fact getting out of it from the other side this instant.

One of the guys even offered the detective a boat so that he could catch the culprit, but the detective wouldn’t agree, instead he decided to get to know the group of young people a little better. Why do you think detective decided to stay and didn’t follow the criminal?

Answer: As I already mentioned the river was deep and rough so if someone would decide to cross it, they would immediately get drowned so there’s no way the criminal could end up on the other end. All of which indicates that the culprit is among those who tried to mislead the detective.
