The Shadow Man by Helen Fields

He collects his victims. But he doesn’t keep them safe…

Elspeth, Meggy and Xavier are locked in a flat. They don’t know where they are, and they don’t know why they’re there. They only know that the shadow man has taken them, and he won’t let them go.
 
Desperate to escape, the three of them must find a way out of their living hell, even if it means uncovering a very dark truth.
 
Because the shadow man isn’t a nightmare. He’s all too real.
 
And he’s watching.

Excellent condition.
