A. A musician has been robbed. His expensive trumpet and clarinet were stolen. They had been kept in his study, which nobody was allowed to enter. Footprints were found on the floor, and traces of someone standing on his/her knees were left in the dust near the desk. His neighbours said they had been out all the week.
B. A summer cottage, belonging to a shop owner has been destroyed. The windows were broken, the furniture was broken too, the floor was covered with dirt and split paint. There was a witness – an old woman who said that she had seen two people in black jumping out of the window on Wednesday night (about 11 p. m.).
C. A 13 – year – old schoolboy has disappeared. Nobody knows where he is, but he has sent his family two messages telling them that he has been kidnapped, but everything is OK with him. He wrote that the kidnappers wanted a ransom (a large sum of money) to set him free.
