A body on the beach. A myth come to life. And a killer who won’t stop…

When a mutilated body washes up on Sennen Beach, DS Liam Kilshaw is plunged into a case as dark and unforgiving as the Cornish winter. With the victim’s face so severely disfigured that identification is impossible, whispers of a local superstition begin to surface—the killing bears a chilling resemblance to the legend of Bucca Dhu, a vengeful sea demon said to demand human sacrifice.

But myths don’t murder people. When a second body is discovered just above the high-tide line, Kilshaw knows he’s racing against time. A missing crew member, a lost shipping container and a trail of cryptic clues all point to something far more sinister.

In a place where folklore and reality blur, Kilshaw must uncover the truth—before the killer strikes again.
