hello, i like reading mystery novels especially Sherlock Holmes
So do I! Sherlock holmes is a fictional detective created by Sir Arthur Conan Doyle.
i like the stories but I also like Conan Doyle writing style it is very efficient 
Sherlock Holmes refers to himself as a "consulting detective" in the stories. He uses forensic science and logical reasoning to solve cases.
he was sort of the prototype of the modern forensic investigator of today
He became popular after appearing in "The Strand Magazine" in 1891.
you know  I need to start reading the stories again I am up to the "Hound" i need to finish the rest
You could read "The Adventures of Sherlock Holmes". It's a collection of 12 stories about him.
