He is Sherlock Holmes's closest friend and the chronicler of his adventures. A former army doctor, he served in Afghanistan. Although he left Baker Street for a time due to his marriage, he possesses the loyalty to return to his detective days at a moment's notice or whenever Holmes is in need. With his medical knowledge, he provides academic support to Holmes from time to time. His logic is sound, but he cannot make the extraordinary leaps of deduction that Holmes does. He is a sensible, moral, and reliable English gentleman. The reader learns of all these incredible events through his slightly bewildered yet entirely objective and admiring perspective. His presence balances Holmes's anti-social traits, which often border on sociopathy.
He served as a doctor in the army, lived camp life in Afghanistan, was wounded, and subsequently returned to England to begin civilian practice. For a time, he shared a flat with Holmes, during which period he bore witness to the solving of many astonishing crimes.
He has the appearance of a sturdy, medium-sized, thick-mustached, well-dressed, mature English gentleman who carries the typical gravity of an army doctor.
