A Question of Blood

Given his contempt for authority, his tendency to pursue investigative avenues of his own choosing, and his habitually ornery manner, it’s a wonder that John Rebus hasn’t been booted unceremoniously from his job as an Edinburgh cop.

He certainly tempts that fate again in A Question of Blood, which finds him and his younger partner, Detective Sergeant Siobhan Clarke, trying to close the case of a withdrawn ex-soldier named Lee Herdman, who apparently shot three teenage boys at a Scottish private school, leaving two of them dead, before turning the pistol on himself.
