A cryptic note to a long-retired policeman. A clergyman stabbed by a masked figure in public. Can Macleod and McGrath find the story behind the panic as it becomes open season on the church?
When a note is delivered to a care home on the isle of Harris, it seems to be a joke in bad taste until the prediction comes true. As more notes are sent and clergy die, Macleod and his team have to open up a wall of silence regarding the reason for such hatred. In a trail that leads across all of Scotland, the DCI finds something more unpalatable than the murders before him.
A wall of silence can only be broken by blood!
