Labyrinth is the 4th and final book in the Cemetery of Forgotten Books series. Context (time and place) is an important feature of Ruiz’ books and this is especially true of Labyrinth: Barcelona is presented as an eerie Gothic wonderland and 1959 features nefarious political and criminal activities. (And at 800 pages, there is lots of space for context!). Labyrinth features the enigmatic Alicia Gris as an investigator tasked with a missing person case, leading to much intrigue as secrets are revealed. And there is some shocking violence. This is a haunting story – highly recommended.
