In preparation for the Sherlock Holmes movie coming out, I decided to first introduce myself to the mystery-solving duo in print. Not very far into “A Scandal in Bohemia,” I ran across some wisdom from Holmes that I thought you might enjoy.

Holmes has just finished reading a letter of unknown author to Watson.

“This is indeed a mystery,” [Watson] remarked. “What do you imagine that it means?”

Holmes responds: “I have no data yet. It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.”
