Jenny Nilson hasn't seen her former psychiatrist Phillip since she left the Hillside Psychiatric Unit eight years ago. She wanted to forget everything about her time there, so she kept her secrets buried deep. Especially from her new husband.

But now the police are knocking at her door with evidence of her involvement in Phillip's death. It seems as though everything she's kept hidden is about to spill out.

Jenny desperately needs to speak to old friends, and old enemies, from those dark years. Because they are the only ones who know what really happened at Hillside, and about the dark secret that Phillip kept for them all - that this is not the first death.
