Feeding the demons - Gabrielle Lord

When Gemma Lincoln wakes up one morning to find her clothes arranged in the effigy of a woman with its throat and crotch slashed, she is sufficiently concerned to consult her friend Angie, a policewoman.

Gemma's father is about to be released from prison after serving a thirty year sentence for the murder of his wife, Gemma's mother. Gemma has always believed he is innocent, as he claimed. Her older sister Kit, however, is sure he is guilty. But if Archie Chisholm didn't kill their mother, who did?
