Everyone has secrets. Not everyone survives them.

When Emily receives a chilling anonymous note—I know what you're hiding—she dismisses it as a cruel prank. But when a second note arrives, with details no one else could possibly know, denial is no longer an option.

Someone has been watching her. Someone knows the truth she's buried for years.

As her carefully built life begins to unravel, Emily doesn't know where to turn. Her husband grows distant. Her friends seem suddenly suspicious. And when a figure from her past reappears, the threats take on a deadly new urgency.

To uncover who is tormenting her, Emily must confront the darkest corners of her past. But the closer she gets to the truth, the more she realises: the biggest secret of all isn't hers.

Chilling, compulsive, and razor-sharp, I Know What You're Hiding is a psychological thriller that will keep you questioning every page, every character, every truth.
