The Murder Inn by James Patterson and Candice Fox is a sequel to the 2019 collaboration, The Inn. I really enjoyed that book and loved the characters in particular. It was slated as a standalone but I said I hoped there were more and…. ask and you shall receive. Though not always obvs.
And I loved this sequel just as much. I literally lapped it up, having returned home from a several-day work trip, I ran a bath and dove right in. To the book, not the bath (into which I stepped carefully).
