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.’
