Secret businesses exposed. Ships sunk. Slavers hunted as they once hunted their victims. All the work of a mysterious sea captain and her ship, the Wraith. Now, two investigators meet to uncover the truth behind the latest disaster: a massacre on an island off the shores of Ketterdam. Among the evidence collected is private correspondence between notorious crime boss Kaz Brekker and the five other members of The Crows. The book comes with a collection of in-world ephemera adding to its immersive experience: A vellum sheet of paper to lay over the book to decipher hidden messages encrypted within the letters … especially those between Kaz and Inejh, revealing details of their secret romantic relationship. A pirate flag and poker chip. Collectable playing cards. With embossing and foiling on the cover. The pages look aged for additional contextual feel, as well as 12 illustrations drawn by the investigator, interview minutes and recording transcriptions.
