A Study in Scarlet by Sir Arthur Conan Doyle introduces one of literature’s most famous detectives: Sherlock Holmes.

When Dr. John Watson arrives in London and begins sharing rooms with the mysterious and highly observant Sherlock Holmes, he soon discovers that his new companion possesses an extraordinary talent for solving crimes. Their first case together begins with a shocking murder, a cryptic message, and a trail of clues that seems impossible to piece together. As Holmes carefully examines the evidence, Watson watches his remarkable methods unfold for the first time. What follows is a gripping mystery filled with deduction, deception, revenge, and unexpected connections reaching far beyond the crime itself. First published in 1887, A Study in Scarlet is the novel that introduced Sherlock Holmes and Dr. Watson to the world—and the beginning of one of the most enduring partnerships in detective fiction.
