Last year Agent Cute had a very interesting case. An English boy Rob went to his pen friend Misha in Russia. His parents came to the detective agency for help. Agent Cute worked on the case. He went to Russia and found Misha and his family. They had a visitor from England — Robin. Agent Cute watched the boys in Russia and, when they went to England, he watched them in England. Robin was from 1599. He came from the past because he wanted to take the Stone of Destiny from Westminster Abbey back to Scotland. The two boys used a time tunnel and swapped places in time and Agent Cute helped them swap back! He found a note, it is the key to a family treasure.
