Freedom comes at a cost... Hetty and Benjy have another death on their hands: Raimond Duval, a victim of one of the many fires consuming Philadelphia. His death is officially declared an accident, but Hetty and Benjy smell something more than just ash in the air. Their investigations point to a powerful Fire Company, known to let homes in the Black community burn to the ground, but before they can investigate further, Raimond's son, Valentine, is also found dead. It quickly becomes clear that there is something more here, something that connects Raimond and Valentine to the recent fires plaguing the city, and Hetty and Benjy have never been the kind to step aside. But this feels larger than the cases that have come before and now their lives hang in the balance. After all, even the most powerful magic can't hold back the ghosts of the past.
