Detective Inspector John Rebus is a hard drinking, unkempt, womanizing police officer whose job is his whole life. He is the most senior and most experienced DI at his station. He has a mysterious past that his partner DS Siobhan Clarke learns about from time to time through various comments Rebus makes. She is a young woman who wants to succeed, but does not have much of a personal life. She feels being paired with Rebus jeopardizes her career because of his unorthodox methods, but she is also fascinated by the man and is extremely loyal. DI Rebus&#39 boss is Chief Superintendent Templar, a woman who was one of Rebus&#39 lovers in a distant past. Their relationship is now one where they barely tolerate each other.
