Gatekeeper 17

Dawn breaks at 3.23AM on the longest day of the year in Scotland’s capital. The first bodies are discovered before 9AM. By the time the third victim’s body is uncovered waves of uniformed and CID officers are arriving in Edinburgh from all over the country. Even DI Boyle, banished to serve out his remaining years on the Force at the Police Training Centre, is recalled to active service.

As hours pass, and the body count mounts, Boyle is confronted by the realization that the country he loves is being used as a killing ground, and that Scotland’s longest day, would be its darkest.
