For a brilliant forensic linguist， crimes of the past hold clues to new series of murders in a twisting novel of suspense by the Wall Street Journal bestselling author of A Familiar Sight。

The double murder of a married couple in a small Washington town draws FBI forensic linguist Raisa Susanto into an investigation that mirrors a decades-old crime。 Twenty-five years ago—to the day—Alex Parker murdered his parents， then took his own life， leaving behind a note admitting everything。

Raisa， paired with forensic psychologist Callum Kilkenny， uses her skills to read between the lines。 Especially now that paranoid postings on a conspiracy thread suggest that Alex was a victim himself—theories that have piqued the interest of a perceptive content moderator and a true-crime podcaster eager for a big break。

As old and new crimes converge， messages from the living and the confessions of the dead take on new meaning for Raisa。 Something more sinister than a copycat crime is at play， and plundering the darkest corners of a killer’s mind leaves her vulnerable to a deadly twist even she never saw coming。
