'It's Mr Jensen,' said the landlord. 'He often stays in
room 14. The poor man must be ill.'
A loud knock sounded on the door of Anderson's room.
Suddenly a man opened the door and came in.
'Please stop that terrible noise,' the man said.
'Mr Jensen!' the landlord said. 'We thought you were
making the noise!'
The three men looked at each other for a moment. Then
they went out quickly into the corridor. The noise was
coming from the door of room number 13!
The landlord banged on the door and turned the handle.
The door was locked.
'I'll bring men to break the door down,' the landlord
shouted and ran down the stairs.
Jensen and Anderson stood outside number 13. The
noise inside the room became louder and wilder.
'I want to tell you something strange,' Jensen said to
Anderson. 'My room has three windows in the day and only
two at night. Perhaps you think I am mad?'
