Poison Ink

Poison Ink tells the story of two neighbouring families who, over the course of five years, were terrorised by a series of sinister and threatening poison-pen letters. As fear and suspicion took hold, they began to question who they could trust. Who was behind the disturbing campaign, and what could they do to bring it to an end?
