Looking for a murder mystery puzzle book for adults that goes beyond a single night? The One Name Remains Complete Series gives you both books in Harbor & Ink Press's most gripping adult puzzle mystery — The Festival and The Island — in one gift set.

In The Festival, you're called to investigate a suspicious death at a summer music festival. In The Island, a new murder unfolds in an isolated resort with nowhere to run. Each book is a standalone interactive puzzle mystery where you interrogate suspects, weigh evidence, and solve the crime yourself. No passive reading — you're the detective.

This is the ideal mystery gift for adults who love true crime podcasts, escape rooms, or anything that makes them think. Perfect for a birthday, Christmas, or "I just need something brilliant to read" occasion.

Both books are written for adults. Best enjoyed solo or tackled with a partner for a fun puzzle night in.
