Dead man's grave / Neil Lancaster.

"The head of Scotland's most powerful crime family is brutally murdered, his body dumped inside an ancient grave in a remote cemetery. This murder can never be forgotten. Detectives Max Craigie and Janie Calder arrive at the scene, a small town where everyone has secrets to hide. They soon realise this murder is part of a blood feud between two Scottish families that stretches back to the 1800s. One thing's for certain: it might be the latest killing, but it won't be the last. As the body count rises, the investigation uncovers large-scale corruption at the heart of the Scottish Police Service. Now Max and Janie must turn against their closest colleagues - to solve a case that could cost them far more than just their lives..."--Amazon.ca.
