Sherlock Holmes

221B BAKER STREET “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.”

The Consulting Detective

Master of deduction, chemist, violinist, and the world’s only consulting detective. Residing at 221B Baker Street with Dr. John Watson, Holmes takes on cases that baffle Scotland Yard.

  • Expert in chemistry & anatomy
  • Skilled in boxing, singlestick & bartitsu
  • Author of monographs on tobacco ash, tattoos & ciphers
  • Employs the Baker Street Irregulars

The Science of Deduction

1. Observe, don't just see

"You see, but you do not observe." Holmes notices the minutiae: a worn cuff, a splash of mud, the type of cigar ash. Everything tells a story.

2. Deduce backwards

Start from the effect and reason to the cause. If a man has a calloused thumb and ink-stained fingers, he is a writer. Combine with location and attire for a complete portrait.

3. Curate knowledge ruthlessly

Holmes's "brain attic" holds only useful facts: chemistry, sensational literature, law, and the geography of London. He famously did not know the Earth revolved around the sun — irrelevant to his work.

Test Your Observation

the game is afoot

A man enters 221B. His right cuff is shiny but the left is frayed. He has a faint smell of ink and turpentine, and a smudge of ultramarine on his collar. What is his profession?
