The Conductors by Nicole Glover

As a conductor on the Underground Railroad, Hetty Rhodes helped usher dozens of people north with her wits and magic. Now that the Civil War is over, Hetty and her husband Benjy have settled in Philadelphia, solving murders and mysteries that the white authorities won’t touch. When they find one of their friends slain in an alley, Hetty and Benjy bury the body and set off to find answers. But the secrets and intricate lies of the elites of Black Philadelphia only serve to dredge up more questions. To solve this mystery, they will have to face ugly truths all around them, including the ones about each other.
