The Piano Man
In 2005 some walkers discovered a man on a road by the sea in the east of England. He was
in his twenties. He had a black jacket, smart trousers and a tie. '_ He couldn't answer any
questions about who he was, or where he came from. It seemed that he didn't have any
memory.
2
They tried to find out if someone pushed him into the sea or if he fell from a boat. But the
man couldn't tell them. He seemed terrified. And nobody knew who he was.
3
At the hospital, one of the doctors had a brilliant idea. She gave him some paper. The
young man drew a picture of a piano on it. The doctors were very excited and took him to a
room with a piano. For many weeks after this, he didn't speak, but he only communicated
with his music. He played for three to four hours every day. Sometimes he didn't want to stop
playing and the doctors had to pull him away from the piano. The doctors called him the
'Piano Man'.
Eventually, the police took a photograph of him and started a social media campaign to
discover who he was. He started to speak to the doctors and he confirmed that he was
5
German and he flew back to his family. A friend of his family spoke on German television and
said that nobody could understand why he ended up in England. And it is still a mystery today!
A
He sang songs and danced around the room.
B Soon after, they took him to hospital.
C
A few months later, his father recognised him from a photo and they discovered that he was from Germany.
D
He started to play a beautiful piece of music and he was calm for the first time.
E The police came and asked him questions, but still he didn't speak.
F But strangely, all of his clothes were completely wet.
