A Study in Scarlet is the first Sherlock Holmes novel and the story that introduces one of the most famous detective partnerships in literature: Sherlock Holmes and Dr. John Watson. After returning from military service, Watson meets the brilliant and eccentric Holmes, and the two begin sharing rooms at 221B Baker Street. Their first case together begins with a mysterious murder in an abandoned London house, where a dead body, strange clues, and a single word written in blood point toward a deeper and more complex crime. As Holmes applies his extraordinary powers of observation and deduction, the investigation expands from Victorian London into a hidden history of revenge, betrayal, and justice.
