Join the search for Typhoid Mary in this early twentieth-century CSI. Now in paperback!

Prudence Galewski doesnÕt belong in Mrs. BrowningÕs esteemed School for Girls. She doesnÕt want an ÒappropriateÓ job that makes use of refinement and charm. Instead, she is fascinated by how the human body worksÑand why it fails.

Prudence is lucky to land a position in a laboratory, where she is swept into an investigation of a mysterious fever. From ritzy mansions to shady bars and rundown tenements, Prudence explores every potential cause of the disease to no availÑuntil the volatile Mary Mallon emerges. Dubbed ÒTyphoid MaryÓ by the press, Mary is an Irish immigrant who has worked as a cook in every home the fever has ravaged. But sheÕs never been sick a day in her life. Is the accusation against her an act of discrimination? Or is she the first clue in solving one of the greatest medical mysteries of the twentieth century?
