My name is Doctor Watson. I am writing this story about my friend, Mr Sherlock Holmes, the famous detective.
Sherlock Holmes lives at 221B Baker Street, in the middle of London. My story begins in Baker Street, one morning in 1889, when a man knocked on the door.
I heard the man say, ‘Mr Holmes? My name is Dr Mortimer. I need your help.’
‘Come in,’ said Holmes. ‘How can I help you?’ ‘I have a strange story to tell you, Mr Holmes,’ said Dr Mortimer. ‘My story is very strange. Perhaps you will not believe me.’
