Portal to Evil — Elizabeth Revill

Adam Barrie has a gift - some would say a curse - and can see and communicate with the dead. When suspicious activity is discovered at the local girls' boarding school, Barrie investigates. What he discovers shocks him to the core. Leonard Shaitan, a charismatic teacher at the school runs a cult and plans to unleash Hell. To do so he must sacrifice a special child. With the help of a vicar who has crossed paths with Shaitan before and a detective out of his depth, Barrie must stop Shaitan before it is too late. He is facing a cataclysmic battle. The fate of the world hangs in the balance. This is the second in the supernatural thriller series with a psychic detective at its heart.
