Sherlock Holmes did a lot of work in eight years from 1880 to 1890. When I look at what I wrote about his work, I can see that he did many investigations.Some were very sad. Some were funny, and many were very strange. There were no ordinary investigations. Sherlock Holmes worked because he liked it, not for money. He most liked to do investigations which were very strange.

A very strange investigation was about a Surrey family, the Roylotts of Stoke Warren. This happened when Sherlock and I lived in the same house in Baker Street. When it happened, I promised not to tell anyone about it. But now the person I promised is dead, and there are a lot of stories about the death of Dr Grimsby Roylott. Some of the stories are as bad as the truth.
