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.
