ARTHUR CONAN DOYLE

Sir Arthur Ignatius Conan Doyle was a Scottish physician and writer who is most noted for his fictional stories about the detective Sherlock Holmes, which are generally considered milestones in the field of crime fiction. He is also known for writing the fictional adventures of a second character he invented, Professor Challenger, and for popularising the mystery of the Mary Celeste.

"Of all ghosts the ghosts of our old loves are the worst.

It has long been an axiom of mine that the little things are infinitely the most important.

Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.

Women are naturally secretive, and they like to do their own secreting."
