Army doctor, Holmes’s companion, and narrator of the overwhelming majority of the Canon. Watson is the reader’s point-of-entry into every case — observant but not omniscient, warm where Holmes is cold, and far more capable than Holmes’s occasional condescension suggests.
Biographical facts
- Full name: John H. Watson, M.D. (middle initial never expanded in canon)
- Military service: 5th Northumberland Fusiliers and Berkshire Regiment; wounded at the Battle of Maiwand (Afghanistan, 1880); invalided home
- Medical practice: maintains a London practice; its location shifts across the Canon
- Marriages: marries Mary Morstan (between Sign of the Four and The Memoirs); she dies (mentioned in passing); Watson apparently remarries (references are inconsistent)
- At Baker Street: lodges with Holmes at 221B Baker Street from A Study in Scarlet through marriage; returns after Mary’s death and at other intervals
Role in the Canon
- Narrator: ~54 of 60 stories narrated by Watson in first person. The two BLAN and LION (in Case-Book) narrated by Holmes himself; MAZA in third person.
- Reader surrogate: Watson sees what the reader sees and is surprised when Holmes is not. This creates dramatic irony without unfairness to the reader.
- Moral compass: Where Holmes can be coldly indifferent (CREE, RETI), Watson expresses the human response. He provides the emotional temperature of a story.
- Competent partner: Most visible in Hound of the Baskervilles where Watson investigates Dartmoor alone for many chapters. He is brave, perceptive, and occasionally decisive.
Watson’s wounds
The Canon is famously inconsistent about where Watson was wounded — his shoulder is mentioned in A Study in Scarlet, his leg in The Sign of the Four. This inconsistency has spawned much Sherlockian commentary.
