Bosch: Legacy will end after season 3, but Michael Connelly's crime universe will continue with the Renee Ballard spin-off series. Despite Amazon canceling Bosch: Legacy and axing the Jerry Edgar solo show, there are still many possibilities to potentially explore in the future with the Bosch-verse brand. One of which, could take the form of a prequel series exploring Harry Bosch's early career in the LAPD, and it could copy the model set out in the upcoming prequel series Dexter: Original Sin.
