The Cracked Wall: Your Killer is Watching You

CSI Eddie Collins has spent his career looking at the dark side of humanity, but he has never encountered anything quite like this.

A predator is watching - not just anyone, but someone who has turned a hidden observation point into their own personal theatre of cruelty. When Eddie stumbles upon the site, he realises he isn't just looking at a crime scene; he has found the secret hiding place of a killer.

Now, Eddie must race against time to unmask a predator who thinks they are invisible. But in a world where even a crack in a wall holds a secret, the most dangerous place to be is exactly where you are.
