DCI Sebastian Turner is a very brash, say what you see style cop, who seems to have his mind set further on clean-up rates and budgets than actually caring whether he catches the killer or not. He quietly oversees the covert competition between his two lead inspectors, Alembic and Dumfries, although regularly shows his despise for Stone, often labeling him as Alembic's "monkey". In the second series, Turner interacts increasingly with his team and is quite often seen out in the field assisting with various investigations.
