The Tenth Door

The Tenth Door: Every Secret Has a Key

For Detective Mark Hill, the case seemed simple—until it wasn’t. Ten victims. Ten locked rooms. And no sign of how the killer escaped.

Each crime scene is identical: a sealed door, a cryptic symbol carved into the wood, and a victim whose past hides more than anyone knew. As Mark digs deeper, he uncovers a chilling pattern—one that leads to a secret society, a decades-old conspiracy, and a killer who’s always ten steps ahead.

The clock is ticking. With his own life now in the crosshairs, Mark must unlock the truth behind The Tenth Door before it’s too late.

This edge-of-your-seat thriller is perfect for fans of dark mysteries, twisted puzzles, and detectives who refuse to quit—no matter how high the stakes.
