The Black Isle: An entirely riveting action-packed mystery thriller (Police Scotland Crime Series Book 12)

A missing brother. Old friends. New Enemies.
When a bungled raid leads DC Craig Hunter back to his old unit in Edinburgh, he has a chance to rebuild his career on a new high-profile case.
When he receives a mysterious message from his brother, Murray, indicating he might have been killed, Hunter must head up to the Scottish Highlands, desperate to pick up his brother’s trail in the Black Isle, the mysterious stretch just north of Inverness.
But the more Hunter digs, the less hope he has of learning Murray’s fate. What was Murray doing up there? Was it connected to his lucrative YouTube channel? Or worse, was it connected to the man housesitting for Murray — Hunter’s estranged father, Jock?
