A Study in Scarlet - Softcover

The story begins in 1881, where Dr Watson runs into an old friend, Stamford. Due to a shoulder injury sustained in the Anglo-Afghan War, Watson was forced to retire and is now looking for a place to live. Stamford mentions that an acquaintance of his, one Sherlock Holmes, is looking for someone to split the rent at a flat at 221B Baker Street, but cautions about Holmes' eccentricities. Stamford takes Watson to the local hospital's lab where they find Holmes experimenting with a reagent for haemoglobin detection. Holmes explains its significance in convicting criminals based on bloodstains. Then, upon shaking Watson's hand, deduces that the doctor has seen military action but waves off the question of how he knows. Watson broaches the subject of their mutual flat-mate search. At Holmes' prompting, the two review their various shortcomings to make sure that they can accept living together. After seeing the rooms at 221B, they move in and grow accustomed to their new situation. Watson is amazed by Holmes, who has profound knowledge of chemistry and sensational literature, very precise but narrow knowledge of geology and botany; yet knows little about literature, astronomy, philosophy, and politics. Holmes also has multiple guests visiting him at different intervals during the day. - wikipedia
