The order the books were released — the default way to read the series.
Bill Robinson is a former Boston police detective who traded the badge for a quiet second act running a seaside inn in Gloucester, Massachusetts -- a retirement that keeps getting interrupted by murder. James Patterson pairs again with Australian crime novelist Candice Fox (also his collaborator on Detective Harriet Blue) to give this series the same regional groundedness, swapping Sydney and the outback for New England's rocky coastline.
The Inn (2019) sets up Bill's new life and the first case that drags him back into investigation; The Murder Inn (2024) continues his reluctant return to detective work years later.
Read The Inn (2019) first to see Bill Robinson's transition from Boston detective to innkeeper and his first post-retirement case. The Murder Inn (2024) is a direct continuation years later and is best read after the first book.
Two: The Inn (2019) and The Murder Inn (2024).
The Inn first, then The Murder Inn, which continues his story years later.
James Patterson co-writes with Australian crime novelist Candice Fox, his collaborator on the Detective Harriet Blue series.
