Creston Books, (2017). SIGNED hardcover first edition - According to the author, this children's book was written both "to introduce an important character in 19th-century history, the first woman detective in the country and to redeem Allan Pinkerton's reputation. Pinkerton and his agency are now chiefly known for violent union-busting tactics, but that wasn't during Allan Pinkerton's lifetime. Rather it was a sharp turn his sons took. Pinkerton himself was a young radical in Scotland, agitating for workers' rights. In fact, he was so successful, the British government considered him a criminal and he had to leave the country or risk arrest. In his new adopted home in Chicago, Pinkerton's house became a busy stop on the Underground Railroad and he was friends with John Brown. He went on to hire people who were generally considered 'undesirable,' including heavily-accented immigrants and women. He was so impressed with Kate Warne, his first female agent, he put her in charge of a whole women's division." An interesting story beautifully illustrated by April Chu. SIGNED by BOTH the author and the illustrator on the illustrated title page, and dated in the year of publication. Author's historical note, bibliography. Large format, unpaginated. ISBN: 978-1939547330.
