Coffin Moon: A Novel by David Putnam is a tense, atmospheric supernatural thriller with strong crime and horror elements. It came out in February 2026. The story mixes small-town secrets, a brutal murder, a grieving detective, and a chilling supernatural presence that blurs the line between guilt and something far darker. It is a standalone with slow-burn dread and a twist that hits hard.
Plot Overview
Detective Ben Coffin returns to his hometown of Moon Hollow, a remote coastal village in Maine, after years away. He left under a cloud—his wife died in a car accident he blames himself for. Now he is back to bury his estranged father and tie up loose ends. The town has not changed: foggy cliffs, weathered houses, suspicious locals who still whisper about the Coffin family curse.
On his first night, a brutal murder rocks the village. A young woman is found dead on the beach below the cliffs—her body arranged in a ritualistic pose, throat slashed, eyes wide open. The scene echoes an unsolved killing from twenty years earlier—the same night Ben’s wife died. The locals call it the work of the “Moon Killer,” a legend tied to the full moon and the Coffin family name.
Ben is pulled into the investigation despite his outsider status. The local sheriff is overwhelmed. Evidence points to a serial pattern: women killed every few years under a full moon, always near the cliffs, always with the same precise cuts. Ben digs into old case files. He talks to people who remember his wife’s death. He finds links he never knew existed.
As the moon waxes, strange things happen. Ben hears whispers in the wind. Shadows move where they should not. He dreams of his wife standing on the cliff, beckoning him. Locals warn him the Coffin curse is real—something in the bloodline draws death. Ben starts to doubt his own sanity. Is he seeing ghosts? Is the killer someone he knows? Or is something ancient and hungry stalking Moon Hollow?
The story builds through Ben’s fractured perspective. Every full-moon night brings a new threat. The town closes ranks. Secrets from the past surface. The final act takes place under a bright coffin moon. The truth is revealed in a shocking, bloody confrontation that changes everything Ben thought he knew about his family, his wife’s death, and the darkness that has followed him home.
Character Dynamics and Development
Ben Coffin is haunted and stubborn. He is a good detective but a broken man. Guilt over his wife’s death drives him. The case forces him to face what he buried. He moves from denial to grim determination. His arc is painful and earned.
The supporting cast is vivid:
- Sheriff Ellen Mayhew – tough, pragmatic, and suspicious of Ben’s return.
- Old Mrs. Coffin (Ben’s grandmother) – cryptic and knowing, keeper of family secrets.
- Local fisherman and bar owner – gossipy, wary, and hiding their own guilt.
- The ghost (or vision) of Ben’s wife – silent, accusatory, and ever-present.
The dynamic is tense and isolated. Ben trusts no one. The town trusts him even less. The supernatural element feels real and oppressive—never fully explained, always lingering.
