The evidence / Christopher Priest.

Todd Fremde, an author of police procedurals and criminal thrillers, is invited to talk at a conference on the remote island of Dearth, far across the Dream Archipelago. Once there, he finds himself caught up in a series of mysteries. How can Dearth claim to be completely crime-free, yet still have an armed police force? Why are they so keen for him to appear, but so dismissive when he arrives? Is his sense of time confused, or is something confusing happening to time itself? And how does this all connect with a murder committed on his home island, ten years before, and seemingly forgotten? Fremde's investigation and research will lead him to some dangerous conclusions...
