The seventh novel featuring Inspector John Rebus, available for the first time as an e-book and featuring an exclusive introduction by author Ian Rankin.

Detective Inspector John Rebus understands that murder is usually very simple. Passion and greed are the most common motives, but when the bodies begin to pile up—two suicides, one murder, and the mysterious death of an inmate in one of Scotland's largest prisons—Rebus realizes that there's nothing simple about his latest case.

What Rebus knows is that it all began with a petty embezzlement scheme. What he discovers is that beneath the killings a conspiracy is hidden, one that runs all the way to the top of the political ladder. And the cost of unraveling this complex web could be horrifyingly high. Everything he holds dear—his job, his life, even his young daughter—is at stake.

Powerful men are telling Rebus to "let it take its course," but none of them will reveal just what it is. Rebus stubbornly decides to go forward with his investigation no matter what the cost may be. Men have died for whatever lies at the heart of this plot, and Rebus is determined that those who have set these events in motion will not escape the punishment they deserve.
