Pinkerton's Great Detective: The Rough-and-Tumble Career of James McParland, America's Sherlock Holmes

"The operatives of the Pinkerton's National Detective Agency were renowned for their skills of subterfuge, infiltration, and investigation, none more so than James McParland. So thrilling were McParland's cases that Sir Arthur Conan Doyle included the cunning detective in a story along with Sherlock Holmes. Riffenburgh digs deep into the recently released Pinkerton archives to present the first biography of McParland and the agency's cloak-and-dagger methods." --
