Eight Detectives by Alex Pavesi

A meta-mystery in which an editor visits a reclusive mathematician-turned-crime writer on a Mediterranean island to prepare a new edition of his seven detective tales, each crafted to illustrate the rules of murder fiction. As they move through the stories, she uncovers deliberate inconsistencies that seem to encode the truth about a long-ago crime, drawing her into a cerebral cat-and-mouse with her host. The layered narratives blur fiction and reality and build toward revelations about identity, guilt, and the stories we use to conceal the past.
