Bonjour,
1. The detective was in Baker Street when he saw the thief.
2. He followed him.
3. The thied got into a taxi and went to a bookshop.
4. He bought a book by Sir Conan Doyle.
5. But he was very unlucky because Sherlock Holmes arrested him when he left the bookshop.
En espérant t'avoir aidé :)
