A chilling and deeply human mystery where buried memories resurface — and the past refuses to stay forgotten.
 
In April 1988, a young man named Michael Sutton walks into private investigator Kinsey Millhone’s office with a disturbing story. As a child, he believes he witnessed a kidnapping — but he can’t remember where, when, or who was involved. With few clues and decades gone by, Kinsey takes the case, unraveling a web of lies that stretches back to the 1960s. Each new lead brings her closer to a truth that someone will do anything to keep buried.
 
U Is for Undertow is one of Sue Grafton’s most layered and emotionally resonant novels, blending a cold-case investigation with a powerful exploration of memory, family, and identity. Switching between Kinsey’s investigation and flashbacks to the 1960s, Grafton creates a slow-burning suspense that examines how perception and trauma can distort truth.
 
As Kinsey pieces together a mystery rooted in long-forgotten secrets, she also confronts the limits of her own empathy and endurance. With sharp insight and deep compassion, Grafton transforms a simple case into a meditation on guilt, innocence, and the shadows of the past.
