Andrew P Sinclair
Andrew writes psychological thrillers from his home in Redmond, Washington, crafting tense, fast‑moving stories where buried secrets refuse to stay hidden. His work explores fractured memory, long‑held lies, and the quiet moments that tip a life off balance.
Born and raised in the UK, Andrew’s sense of atmosphere was shaped by the country’s landscapes and layered histories. Now living in the Pacific Northwest, he draws on its brooding forests and shifting weather to sharpen the mood of his fiction. Together, these influences define the tone of his debut novel, Water’s Edge, set in the UK and rooted in the places and unease of his early life.
Andrew is currently completing his debut novel, Water’s Edge, and working on his next psychological thriller.
Water's Edge
A psychological thriller by Andrew P Sinclair.
Coming early 2027.
"Time to tell the truth."
Five words on the back of a photocopied newspaper clipping.
Steve has spent fifteen years trying not to think about what happened that summer. About the river. About the lie he and his friends told, and the silence they agreed to keep.
He’s built a home with Kate. A future. A version of himself he can live with.
Then the notes begin to arrive. A warning. A photograph. Proof that someone remembers.
Steve needs to find out who is sending them before the truth comes out. Because if it does, he won’t just lose Kate. He could lose everything he’s built. Even his freedom.
And Steve isn’t the only one with something to lose. Max and Dusty shared the lie, and someone seems determined to drag them all back to what happened on April 5 1986.
As the pressure mounts, Kate senses the man she loves is pulling away from her one lie at a time.
Can Steve keep the past buried? Or will the truth destroy everything he’s built?
Water’s Edge is a slow-burn psychological thriller about the lies that hold a life together, and the truth that finally pulls it apart.
