John Watson

Sherlock Holmes’s flatmate and blogger seems harmless enough when you first meet him, but don’t let the frumpy exterior and questionable taste in sweaters fool you. Underneath the plaid and knits is a sharp-eyed ex-soldier and adrenaline junkie who loves the chase almost as much as his partner-in-crime-solving does.

Joan Watson

Elementary’s Watson may be a Joan instead of a John and traded in a soldier’s firearm for a sober companion’s exasperated patience, but don’t underestimate her. She not only keeps up with the deductive skill of Sherlock Holmes, she does it all while running around New York in two-inch heels.
